my company uses cat and cummins isx. the intermodal uses 579s and volvos with 600 hp isx and the flatbed and heavy haul uses cat c15s and c18s. we have a c500 with a quad turbo 3412 (1300+ hp) for 150 ton heavy hauls. the cummins dont break down much and get 8+ mpg and seem to be money makers. the cats (especially the c18s) have more power but burn more fuel. break downs are not common theyre both pretty solid. if i was an owner operator it would be a volvo with a cummins over a 379 with a c15 or c18.
9-11-2023 Praise our first responders. When I started driving professionally, I was informed to never allow the pyro to hit 1200. I could do very serious damage to the engine. So I held to that reasoning. even though this is 7 years ago It really hits home. These drivers today have no idea what this is about since the computer will not allow it to happen.
I did a rerate to my 3126. It was gutless, 175hp. Dealer said I could go to 190 with no changes. 210 if I changed the turbo, or 230 if I did the turbo and injectors. I’m sure injectors would’ve been pricey, so I installed a reman turbo. It seemed the only difference was the new turbo has a wastegate. Then I had them do the rerate. It’s still slow, but definitely noticed it has more power.
I am confirmed. I read the Pittsburgh Power past articles in a Truck magazine. "Cannot understand why rebuild and not also increase rhe horsepower?" and "The rebuild price is about the same for a. 350HP as it is a 550HP engine" and "Improve fuel mileage" "You only live once'". I am benefiting from longevity with a low rated 370-435HP Cummins N14 Celect Plus (It is to increase the horsepower and torque in the last two gears only when going up a grade). I do actually feel it kuck in at times. It has 43.5k hours and over one million miles. Day cab undef 4.7k idle hours. Intermodal also helps: I am not hauling steel or heavy liquids. Most loads I pull are are under 30k lbs net. I am empty 50% of the time. I do care about gradeability: I just run my low horsepower N14 at 1450-1600 when loaded and chop my way the upper midwest hills. Eaton 13-Speed allows me to stay in the aforementioned range 95% of the time from 20MPH to 65MPH. I drove and MBE 4000 for a while with a 10-speed. Good low end for the bottom eight gears dow to 1,000. Poor Volvo Detroit lije gradabimity losing 10MPH up 3% grades. Cats may be the most poweful engine but in my experience they are also rhe most thirsty. I average 6.25-6.5 with my N14.
Cummins in Amarillo Tx did just that to my 97 freightliner with a N-14. I went from 435hp ( 1600 trany torque ) to 525hp ( 1850 Trany torque ) and daammmmm that’s a beast now. Cost ???? $$$ 350
The highest torque rating you can get is 2050 for the transmissions but trucks at sled pulls put out 3,000 plus foot lbs through these or lower rating transmissions with no problems. It's all about proper use of the transmission.
If your Cat dealer has dyno I would also recommend a PAR dyno. Just because you engine flash file is for 500hp it doesn't guarantee your engine is producing 500hp. The engine is run on a dyno at the factory when it was build and the fuel rates were adjusted to with in normally 1 or 2 hp of what ever your rating happens to be. In some rare cases after an engine has been fully broken it or is several years old it can be up to 15 to 20hp low at the rated RPM and sometimes even more in the usable RPM range of 1100-1600RPM. If the dealer has a PAR certified dyno they can adjust the fuel rates back up to meet or slightly exceed factory specs for your engine rating. I have always recommended doing a PAR dyno before doing a top end and not after. The reason for this is if you valve lash is on the loose side you are loosing valve lift and reducing hp, when the injector rockers and rollers seat in and start to wear this normally retards timing reducing hp and throttle responce. Doing the PAR dyno before to top end set will compensate for this and bring your hp back up to spec. Then when you have your top end set it will advance the injection timing and the tighter valve lash will increase the valve lift for on average of about a 10hp gain. Not a huge number but in some cases every little bit helps. It might be helpful for some guys if you have a video to better explain what a PAR dyno is. In some cases it may not be available since most dealers don't invest in the required building separate from the shop, the very expensive dyno equipment and the trained technicians to operate it due to the low demand and profit. Hope this helps
A re-rate here At Blanchard in Summerville SC according to them is 750 for the Cat password to get into the ECM then 2 hrs labor. About a grand. I'll run my c15 475 and like it for a bit longer.
This was useful in trying to understand why an engine with 775,000 (Mack) might fail if the HP was increased from 415 to 485. FYI, over-runs on the engines were eight with each instance being more than a half hour! Must have been some enormous hills to descend. Again, I am neither a mechanic nor driver so I don't know. But I do know that the only change to the engine in the shop was software - no hardware at all.
I built a 3406E for a customer 5Ek was the stock engine family He wanted a serious up grade and buying all cat parts we put 6nz parts on his engine loaded liners head , cam, injectors and turbo being 19k in parts we had a rerate for the Ecm print out was 550 hp @ 1400+- rpm 1300 +- torque at 1400rpm i think it was a genset file not sure but oh man that truck will pull 100k up hills in sc like nothing else in the area kinda like it doesnt care how much weight it pulls never more that a dark grey cloud of exhaust smoke and clearing right up. The man is super pleased with his engine after 10years. Question educated guess on power at 2300rpms the print out states hp and torque at a very low rpm setting it would be interesting to know what it has at high idle
Yeah this what I do to electric Cummins motors, I take em to the Diesel Doctor I'm Effingham, IL and have him turn the motors up via file thru the ECM port. He normally turns em up to max 600hp 2050 ft/lbs torque if it's a non dpf motor or max 550hp 1850 ft/lbs torque for a dpf motor! I just didn't know it was called a rerate!
Just bought another MBN C15, @ 435HP. Had CAT turn it up to 525HP, as it states on the passenger side of the motor. You have to find the right CAT tech for the job, because I've found out that most guys won't do it.
Adept Ape thanks for video . I have c15 6ng single turbo . My fuel mileage is around 4 mpg . I put new turbo and manifold by cat but fuel mileage is still 4 mpg . Need some help
A ecm comes a dime a dozen. Just need to know the right people. I goto computer king in Dickinson tx. They warranty everything. And if you have a faulty one, they’ll hook it up to they’re truck. But I had a faulty one and came out at $850 with core.
Forgive me, I know you get a million questions! If you don't have time, maybe some of the other guys can help. I'm try to find information on the best operating rpm range for a 2001 C-15 6NZ single turbo pre-emission. I'm averaging 6.0 mpg and normally keep it around 1400 rpm's in whatever gear for the speed limit and try not to let it get over 1800 rpms under jake down hill. I'm looking at a chart for horsepower put out by "Road Choice" Truck parts online and it references a 500 hp testing at 2100 rpm's putting out 1850 ft lbs. 2100 is not a working range is it??!! Again we truly appreciate all that you do for us!!
Peak torque is at 1200 rpm. If I remember right 2120 rpm will be your top engine speed limit. You get your torque down low and your horsepower up high. A lot of people dont want to lug the engine but a C-15 can take it, and really its where the torque is. If its running right you shouldn't have no problem pulling right out of it. Generally keeping the rpm low most of the time is gonna make the engine last longer. I overhauled one for a guy one time who kept his rpm low and changed oil religiously. It had over a million miles on it and the rod and main bearings looked brand new. 6NZ is a legend so make sure you hang on to it and keep rebuilding it.
my friend has a 3406b 7fb with 40 psi+ lbs. of manifold pressure it will go higher but he said the turbo he has the guy who sold it to him said 40 psi was the max and the pry never goes over 900 he owned this truck for many years like this and get 7mpg on the highway and when im behind him I never see any smoke come out the stacks
I am considering deleting the regen system on a C15 to add horse power and decreasing maintenance cost which have been very expensive. I saw your video on rerate if successful I would be adding horse power but would still be stuck with the regen maintenance cost. I have spoken with others that deleted the regen and increased horse power and received better milage. Your thoughts please
I've wondered about the C7s in the more recent BAE military 2.5 tons from the teens, would they be in the emergency family? Really I'd wondered because it was the military ordering them with the wide range of fuel requirement, were they saddled with the same emissions kits as the civilian trucks from the same years?
Wowzers, you get alot of comments! I don't know how you keep up with them all. I must say that I love your channel. Your devotion to educating others about CAT diesels is really cool! I enjoyed studying the C7 engine family re-rate chart you showed in this video. Do you have a chart of these families for the 3126B/3126E? It would be very interesting to look at (I like numbers!). I'm thinking about buying a bus and considering the T444E and 3126 as possible choices, but it will be a while before I can afford one. I know little about the CAT motors, but I've been learning quite a bit watching your channel. As a side note...do you ever plan to do a video on how to set the injectors (synchronization) for a 3116? I have no need for this, but just find the topic really interesting. I imagine there aren't that many out there these days, but probably still a few. I know a guy who used to work at a CAT dealership and said they were an awful pain to do. He was the only one in the shop who could (or would) do them. Thanks for any information you have. Keep up the great videos!
+Jonathan Bopp I used to reply to every comment before, but I don't have enough time for that now. I'm not sure when I'll do a 3116 rack sync video. We only get them about every 6 months, but I'm the lucky guy that gets to do them. They are very tedious to do. It isn't that they are crazy hard it is just a ton of little steps and the Cat instructions are hard to follow. As far as the 3126 rerate chart, probably won't be putting that up online because it is much more difficult to follow. It is much more component dependent and is several pages long.
I can see where keeping up with so many comments would be time-consuming. I figured you didn't see too many 3116s these days, but I know they are still out there. I rode on a 1995 Bluebird GMC bus for years and it had the 3116. It never failed us, but was a real dog starting out...particularly on a hill. The turbo lag on them (or at least the later models) was something awful. The mechanic I knew said that they used to get that complaint at the dealer constantly. He said they would put the bus in gear and push down the pedal to see how many seconds it took the engine to reach a specific rpm. If the time was too long, there was an adjustment screw you could adjust to turn up the pre-boost fuel. I realize doing a video on that would be tedious and time-consuming. I know the timing of when you get one also might not be at a convenient time to do a vid. From the little I know, the process is vaguely similar to Detroit's "rack" system. Ah, so it would seem that a re-rate on a 3126 would involve more than than flashing the ECM in most cases. I had just assumed that it was similar to the C7s. If you ever get motivated, I'd still find the chart interesting, even if nobody else did. I love specifications and numbers. Thanks for all you do for all those who watch. I'm going to send you a donation this evening. :)
My 550hp 6nz now runs around 700hp. Different turbo and program. I can not make my exhaust temp go over 1000 degrees without severely lugging the engine. Stock form it easily climbed higher. There is a good way and bad way to add power. Anyone I've known that has done a factory cat rerate has noticed little to no difference. Love your videos though. Thanks for what you do
+Mitch Less I'm sure there are ways to tune your engine better than factory, but it is easier to mess up than make it run better. Sounds like you know what your doing. Glad you like the channel.
THAT was the most enlightening information that I've had in a very long time!THANK YOU!!!Just a thought,I wonder does that apply to all BRANDS?Like I said,just a thought!
Tell all you need to know in a clear manner Im looking to rerate a C15 435 for pulling a low loader with an allowable gross weight of 59 tonnes/130000lbs
Can you rerate to the fire/Rv ratings now that the 3126 are beyond any factory warranties? I have a 190hp 3126 in a 2001 C5500 and would like at least to be at the 300/860 mark but more is better. I have seen the PDI tune/turbo/manifold aftermarket options but not sure if worth putting on a such a low HP engine. I assume it would be cheaper just to find a running used engine in the HP range I’m looking for. What do you think is the most cost effective way to change 190hp into 300hp?
+mehmet g Well the C15 is the standard truck engine, it is heavier and 15 liters of displacement. The C15 makes more power and torque and is an overhead cam engine. The C13 is usually found in buses and some trucks. It is 13 liters of displacement and is a pushrod engine. Both use Mechanical Electronic Unit Injectors with a gear drive oil pump and water pump. The C13 is more sensitive to overheats causing damage and the C15 has more problems with its overhead and liner flanges.
installed the edge chip on my 3126 was very happy till check light came on after 1000 miles. reset and was fine. then heading down freeway and engine went to a idle. lemp to rest stop and unhook chip and ran fine. out $800 bucks. called edge said they discontinued that chip.
Go into et configure with retarter Free hp nothing else needed. Already wrote into software Give you about 15% more power Looks like your blowing alot of white smoke
I have a problem with a truck I am working on and $3600 and counting haven't been able to get it running . Is there a contact or place I can get in touch with you regarding this truck . 2006 F650 C7 Acert engine - replaced cam, cam followers , rod bearings , crank bearings, oil pump , 3 ecm's , engine wiring harness
Zeigler CAT of Rochester, Minnesota says that they don't/won't do a re-rate. States that CAT "won't allow us to." Is this common? They sent me next door to Rochester Diesel. They say 100HP for @ $2000 parts/labor. That seems odd. It's a 2000 3126 f650 that started out as a 26' box truck , shortened & now has an f350 box. It's just a big toy I use to tow my 42' travel trailer a couple times a year. Not sure now exactly what to do. I'm just looking for an improvement in fuel economy. Any suggestions?
I have a 2005 lexion combine with C9 engine. It's at 360 hp. Can we safely add more hp? Not driving the snot out of it. Just need a boost once in a while
awesome video, I'm quite interested in hearing more about the tuning end of things with not only Cats but on diesels in general. keep up the good work my friend.
Thank you for the kind words. The tuning on these engines can get pretty intense, but I just wanted to show that there is also a Cat certified alternative to the aftermarket.
i still find it hilarious that you can plug in a computer and load a tune for a 550 or 600 horse C15 onto a motor that originally had 425-435 from the factory. perks of having a Cat versus a Cummins or Detroit lol.
Very nice info. Hey boss, where are you from?. I got 1.3 mill on my pete 379 with cat, c15mxs. Start leaking right next to head. May be you can help me. Can you? Thanks
Hi I have a few questions , First I have a 2001 Pete 379 with a C-15 6NZ . I am a John Deere Agricultural field tech with 20 years of Deere experience I work with a laptop daily we use a Data link the same as Cat to upload payloads and files . The questions I have are , I am looking at purchasing a laptop and data link with Cat ET installed I want to be able to hook up to my truck and tune the HP , also pull codes when needed and perform diagnostics . I have heard a lot of talk about flashing the ecm and also talk of Mapping the ecm what is the difference , also were can I get these flash files and how will I know which one is the correct one . Are they On cat SIS ? any info would be great Thanks.
+farmerjoe338 The flash file is what sets the horsepower, there really isn't any mapping you can do. You can mess with the FLS and FTS setting, but that requires a factory password. The flash file is also going to require a factory password. The flash file is downloaded from Cat.
Makes total sense Deere does the same thing where you have to be a dealer tech with a password to do things such as this . I am trying to figure out how this guy on UA-cam Steven Bradford ( aka catlepuller ) is getting the horsepower and getting these kitty cats to do what they are doing . I asked him and he said he maps the ECM could you please watch some of his vids and give me your opinion it would be greatly appreciated. Thank you my friend .
good morning adept,I want to thanks you for the videos that you have make us,I really learn alot of things from them,pls can you make video for me,a video of how to drup and engine from the a track☺☺
It can invalidate your wanty ... Engine infirmation tag rough cover front timing cover. Previous owner had it.. 9 to 13 pages. Go to a cat dealer wanty downloader .. rerate danger. Corrupted flash file.. does not require any monetary value... Chance that it might damage current ucm....
I just bought freightliner with a C7 and I pull my RV with it and we be honest with you I love my set up but when I’m go uphill The truck struggles a lot will you recommend me to do a rerate basically I need help. I hope you can do that for me and also, if you can recommend me where can I take my truck appreciate it peace.
I have Cat ET at my work. I mostly use it for diagnosing fault codes on C7 Cats in school buses. My dad just bought a 2000 Kenworth with a C-15 6NZ 475 HP engine in it. He is complaining about the lack of pulling power in it compared to his old 3406C. Am I able to rerate his engine for him with my basic Cat ET program? If so, do you think you could make a video of it? Or at least explain where to find it in ET? I don’t work on Cat much, usually Cummins. On a Cummins I would just download a file from QuickServe.
I have a c-15 serial SDP how can I find the chart that you used in this video to see how high I can go with my HP This is in a 2008 Pete and it had been deleted by 2nd previous owner. Shows 475hp on the computer but KW tech said it could be different HP because it has been deleted is this correct and how can I find out what the HP is? thank you for your time.
fantastic vid my freind!! ty!! for this! my 2005 KW! C-15 acert! z model the cat boys around my parts! tell me is junk! well at 800k she's still goin strong! Rto 13SPD and 3.36 rears! She will pass anything on the big road! all day! but at 80 thousand plus I lose a full gear and a split! do you think a rerate would help her? TY From Idaho USA!
+CAT POWER OR BUST! (ALLDAY) A rerate if you are pulling heavy a lot is a good idea. Now it just depends what your current rating is and then seeing if your transmission can handle a bump in torque as well.
ok...why can't my local cat shop update the personality file so it can be turned up to a 550...5ek updated internals 455 stock.... had to recode injectors just to get this paper weight out its own way...lol..even my local repair shop can't get it to take the 550 keeps failing with personality file...
I have a c13 in a 07 freighter with the smart shift trans I was told we need to have the transmission put in performance mode but none of our cat shops around here have never heard of that would you have any suggestions
So I'm not very seasoned in this stuff. My question is how this really effects the output of the engine. We've had a couple peterbilts that are twin turbo acert motors. Not sure of the mxs, bxs etc, but one was a factory 475 and the other was 550 from the factory. The 475 was rerated to a 550 but I can say it does not pull like the 550 from the factory. there's a definite difference. Gearing and transmissions are the same. Can you explain why this is? What's the difference mechanically and electronically from the 475 and the 550? It seems whatever they came as from the factory is what they operate best at.
+Justin Hood The twin turbo Cats use the exact same components from 475 to 550. There are differences if you go above that for a heavy haul or RV engine, but you are dealing with the same injectors, valve lash, camshaft, everything. My guess would be the rerated engine has a problem like a boost leak or low fuel pressure.
Torque Rating on the Motor could also be different as well. If there is Nothing Wrong with that Motor, then it is the Torque Rating on the Motor. My guess is that The 550 HP Motor is a 1850 Torque and The 475 HP Motor is a 1550/1650 Torque Motor.
I have a couple of questions on rerate 1. when you rerate is there a program that changes to horse power and I don't know what you call it but is like changing from pulling a dry van to a heavy haul? 2. I have the computer and the cat et and also the flash files and password generator programs just not really sure how to use is there a computer program that will break it down step by step on how to use or what can I do to learn this with out having to go to cat school not looking to do this on any other truck but mine
+David lemons I don't really know what you mean about changing to a heavy haul horsepower. The horsepower is just set by the flash file. I don't know of any detailed online Cat training program. Most guys just learn from factory training or from each other. I have a video on how to program an ECM, but it doesn't cover how to rerate. Be careful if you try to rerate as Cat tries to charge a $250 fee for the rerate or else it might lock your engine at idle.
Adept the heavy haul is not an increase in horse power it is settings that is put in ecm to help with the extra weight in heavy haul . If you order a new truck you are ask what you are going to do pull van freight or flat bed or RGN ( heavy haul ) and when they tune the engine at the factory they have different tunes for different applications. I know you can go to a Cat shop and do a rerate and if you ask they will put what they call a heavy haul package in the ecm. I guess what I'm asking is do you have or can you do a list of steps to do a rerate and how to generate and cat password I do have both programs I'm just not real familiar with how to use them yet
I gotcha, I thought you were asking how to change the setting on the horsepower for the engine to heavy haul or light freight. So the heavy haul designation is actually the flash file and typically it's a high horsepower designation. I'm not going to do a video on how to do a rerate yourself, as almost nobody has the tools to do it themselves and it is easy to mess up. My fear is that if you rerate it and then need the factory passwords for a rerate, your engine is going to get stuck in idle only.
im looking for a pre emission truck and found a pete 379 with a 3406 5ek engine with 550 hp with new platinum overhaul from cat would that increase in hp damage engine from overheating. its probably a different pistons pack but all that extra heat what u think ?
What can I do to get more hill pulling power out of my 3208T? It's in a motorhome, pulling hills can be a pain, struggling at 35 mph on some hills.. bigger turbo? Fuel adjustment?
![Will It Haul? CAT 3126 swapped F-350 Tuned Up to 330 HP #FTreeKitty [EP28]](/img/n.gif)
I think Its Great what you do AdeptApe! Thank you from Proud C15 Acert owner!
That was a really good way of telling the pros and cons of both sides of the story, at least for someone that has worked on them. Thank You.
my company uses cat and cummins isx. the intermodal uses 579s and volvos with 600 hp isx and the flatbed and heavy haul uses cat c15s and c18s. we have a c500 with a quad turbo 3412 (1300+ hp) for 150 ton heavy hauls. the cummins dont break down much and get 8+ mpg and seem to be money makers. the cats (especially the c18s) have more power but burn more fuel. break downs are not common theyre both pretty solid. if i was an owner operator it would be a volvo with a cummins over a 379 with a c15 or c18.

I did a rerate to my 3126. It was gutless, 175hp. Dealer said I could go to 190 with no changes. 210 if I changed the turbo, or 230 if I did the turbo and injectors. I’m sure injectors would’ve been pricey, so I installed a reman turbo. It seemed the only difference was the new turbo has a wastegate. Then I had them do the rerate. It’s still slow, but definitely noticed it has more power.
Garbage engines those 3126s are. How you gonna get 200hp out of 7.2l?
@@benjaminturpin2749 7.2 isn't the problem, it's the design of the engine , it's a natural turd

I do care about gradeability: I just run my low horsepower N14 at 1450-1600 when loaded and chop my way the upper midwest hills. Eaton 13-Speed allows me to stay in the aforementioned range 95% of the time from 20MPH to 65MPH.

Cats may be the most poweful engine but in my experience they are also rhe most thirsty. I average 6.25-6.5 with my N14.

I built a 3406E for a customer 5Ek was the stock engine family
He wanted a serious up grade and buying all cat parts we put 6nz parts on his engine loaded liners head , cam, injectors and turbo being 19k in parts we had a rerate for the Ecm print out was 550 hp @ 1400+- rpm 1300 +- torque at 1400rpm i think it was a genset file not sure but oh man that truck will pull 100k up hills in sc like nothing else in the area kinda like it doesnt care how much weight it pulls never more that a dark grey cloud of exhaust smoke and clearing right up. The man is super pleased with his engine after 10years. Question educated guess on power at 2300rpms the print out states hp and torque at a very low rpm setting it would be interesting to know what it has at high idle
Yeah this what I do to electric Cummins motors, I take em to the Diesel Doctor I'm Effingham, IL and have him turn the motors up via file thru the ECM port. He normally turns em up to max 600hp 2050 ft/lbs torque if it's a non dpf motor or max 550hp 1850 ft/lbs torque for a dpf motor! I just didn't know it was called a rerate!
Just bought another MBN C15, @ 435HP. Had CAT turn it up to 525HP, as it states on the passenger side of the motor. You have to find the right CAT tech for the job, because I've found out that most guys won't do it.
+sTEVAL570 I think many people are intimidated about it, unless you've done it before it can seem hard to find the information to do a rerate.
Adept Ape thanks for video . I have c15 6ng single turbo . My fuel mileage is around 4 mpg . I put new turbo and manifold by cat but fuel mileage is still 4 mpg . Need some help
Clean the soot🤔
Thank you as always for sharing your knowledge brother😎
Awesome.. I like your channel got 2 c-15s and you been very helpful.
I just bought a ecm from goecm for 1375 . Had it in 3 days from when I ordered it .
trucks and 966 loaders.great engines.
Does rerating require a change in the governor?
Hi I have C 13 industrial engine and it runs for 5 years without service
C13 AND 3306B HAVE SIMILAR PARTS ON VALVES SETS AND VALVE STAM.
Ok...am i the only saw that lady walked across the room @7:59m
Hey what do you recommend for a fuel additive to clean the injectors? If there's such a product out there?
A ecm comes a dime a dozen. Just need to know the right people. I goto computer king in Dickinson tx. They warranty everything. And if you have a faulty one, they’ll hook it up to they’re truck. But I had a faulty one and came out at $850 with core.
Good Channel and Good video. Keep up the good work, drivers need a Mechanic doing videos from your perspective.
Forgive me, I know you get a million questions! If you don't have time, maybe some of the other guys can help. I'm try to find information on the best operating rpm range for a 2001 C-15 6NZ single turbo pre-emission. I'm averaging 6.0 mpg and normally keep it around 1400 rpm's in whatever gear for the speed limit and try not to let it get over 1800 rpms under jake down hill. I'm looking at a chart for horsepower put out by "Road Choice" Truck parts online and it references a 500 hp testing at 2100 rpm's putting out 1850 ft lbs. 2100 is not a working range is it??!! Again we truly appreciate all that you do for us!!
Peak torque is at 1200 rpm. If I remember right 2120 rpm will be your top engine speed limit. You get your torque down low and your horsepower up high. A lot of people dont want to lug the engine but a C-15 can take it, and really its where the torque is. If its running right you shouldn't have no problem pulling right out of it. Generally keeping the rpm low most of the time is gonna make the engine last longer. I overhauled one for a guy one time who kept his rpm low and changed oil religiously. It had over a million miles on it and the rod and main bearings looked brand new. 6NZ is a legend so make sure you hang on to it and keep rebuilding it.
my friend has a 3406b 7fb with 40 psi+ lbs. of manifold pressure it will go higher but he said the turbo he has the guy who sold it to him said 40 psi was the max and the pry never goes over 900 he owned this truck for many years like this and get 7mpg on the highway and when im behind him I never see any smoke come out the stacks
+John Thomas These engines can handle power, this truck must be hot rodded because that is a lot of boost.
I am considering deleting the regen system on a C15 to add horse power and decreasing maintenance cost which have been very expensive. I saw your video on rerate if successful I would be adding horse power but would still be stuck with the regen maintenance cost. I have spoken with others that deleted the regen and increased horse power and received better milage. Your thoughts please
Very interesting 🤔
Good information, thanks 👍🏽
I've wondered about the C7s in the more recent BAE military 2.5 tons from the teens, would they be in the emergency family? Really I'd wondered because it was the military ordering them with the wide range of fuel requirement, were they saddled with the same emissions kits as the civilian trucks from the same years?
The smaller BAE LMTVs
КЕТ РУЛИТ!!! ХОРОШИЙ ДВИГАТЕЛЬ!!! БОЛЬШОЙ РЕСУРС!!!
Wowzers, you get alot of comments! I don't know how you keep up with them all. I must say that I love your channel. Your devotion to educating others about CAT diesels is really cool! I enjoyed studying the C7 engine family re-rate chart you showed in this video. Do you have a chart of these families for the 3126B/3126E? It would be very interesting to look at (I like numbers!). I'm thinking about buying a bus and considering the T444E and 3126 as possible choices, but it will be a while before I can afford one. I know little about the CAT motors, but I've been learning quite a bit watching your channel.
As a side note...do you ever plan to do a video on how to set the injectors (synchronization) for a 3116? I have no need for this, but just find the topic really interesting. I imagine there aren't that many out there these days, but probably still a few. I know a guy who used to work at a CAT dealership and said they were an awful pain to do. He was the only one in the shop who could (or would) do them.
Thanks for any information you have. Keep up the great videos!
+Jonathan Bopp I used to reply to every comment before, but I don't have enough time for that now. I'm not sure when I'll do a 3116 rack sync video. We only get them about every 6 months, but I'm the lucky guy that gets to do them. They are very tedious to do. It isn't that they are crazy hard it is just a ton of little steps and the Cat instructions are hard to follow.
As far as the 3126 rerate chart, probably won't be putting that up online because it is much more difficult to follow. It is much more component dependent and is several pages long.
I can see where keeping up with so many comments would be time-consuming. I figured you didn't see too many 3116s these days, but I know they are still out there. I rode on a 1995 Bluebird GMC bus for years and it had the 3116. It never failed us, but was a real dog starting out...particularly on a hill. The turbo lag on them (or at least the later models) was something awful. The mechanic I knew said that they used to get that complaint at the dealer constantly. He said they would put the bus in gear and push down the pedal to see how many seconds it took the engine to reach a specific rpm. If the time was too long, there was an adjustment screw you could adjust to turn up the pre-boost fuel. I realize doing a video on that would be tedious and time-consuming. I know the timing of when you get one also might not be at a convenient time to do a vid. From the little I know, the process is vaguely similar to Detroit's "rack" system.
Ah, so it would seem that a re-rate on a 3126 would involve more than than flashing the ECM in most cases. I had just assumed that it was similar to the C7s. If you ever get motivated, I'd still find the chart interesting, even if nobody else did. I love specifications and numbers.
Thanks for all you do for all those who watch. I'm going to send you a donation this evening. :)
Just curious how hard is it turn up 3116 have one in 96 topkick says 170 hp but a tick more would be nice nothing crazy just dab @AdeptApe
Can you trun a 3126 up
Can you please tell me where can I find those re-rate charts at 4:45 in this video? I am looking for the family delineations for my 3406E 5EK. Thanks!
My 550hp 6nz now runs around 700hp. Different turbo and program. I can not make my exhaust temp go over 1000 degrees without severely lugging the engine. Stock form it easily climbed higher. There is a good way and bad way to add power. Anyone I've known that has done a factory cat rerate has noticed little to no difference. Love your videos though. Thanks for what you do
+Mitch Less I'm sure there are ways to tune your engine better than factory, but it is easier to mess up than make it run better. Sounds like you know what your doing. Glad you like the channel.
THAT was the most enlightening information that I've had in a very long time!THANK YOU!!!Just a thought,I wonder does that apply to all BRANDS?Like I said,just a thought!
Im considering buying a 310 catapiller 3406 1992 FREIGHTLINER FLA104, can this be done with this semi truck? Thank you
Tell all you need to know in a clear manner
Im looking to rerate a C15 435 for pulling a low loader with an allowable gross weight of 59 tonnes/130000lbs
That answered ALL of my questions. Thank you.
Can you rerate to the fire/Rv ratings now that the 3126 are beyond any factory warranties? I have a 190hp 3126 in a 2001 C5500 and would like at least to be at the 300/860 mark but more is better. I have seen the PDI tune/turbo/manifold aftermarket options but not sure if worth putting on a such a low HP engine. I assume it would be cheaper just to find a running used engine in the HP range I’m looking for. What do you think is the most cost effective way to change 190hp into 300hp?
"Your engine family that is" LOL
can you tell me the difference between C13 verses C15 ? which is better ?
+mehmet g Well the C15 is the standard truck engine, it is heavier and 15 liters of displacement. The C15 makes more power and torque and is an overhead cam engine. The C13 is usually found in buses and some trucks. It is 13 liters of displacement and is a pushrod engine. Both use Mechanical Electronic Unit Injectors with a gear drive oil pump and water pump. The C13 is more sensitive to overheats causing damage and the C15 has more problems with its overhead and liner flanges.
installed the edge chip on my 3126 was very happy till check light came on after 1000 miles. reset and was fine. then heading down freeway and engine went to a idle. lemp to rest stop and unhook chip and ran fine. out $800 bucks. called edge said they discontinued that chip.
What are your thoughts on diesel freaks power harness could you maybe do a video on the pros and cons?
I learned a lot. Thanks
Am really enjoying your video,thanks a lot
Dude, you're the man
Go into et configure with retarter
Free hp nothing else needed.
Already wrote into software
Give you about 15% more power
Looks like your blowing alot of white smoke
Really good information, thanks
Thank you for the kind words.
Where can I find the charts that you show in this video?
I have a problem with a truck I am working on and $3600 and counting haven't been able to get it running . Is there a contact or place I can get in touch with you regarding this truck . 2006 F650 C7 Acert engine - replaced cam, cam followers , rod bearings , crank bearings, oil pump , 3 ecm's , engine wiring harness
Adept Ape any recommendations on Detroit Diesel 8.2T turbo??
Zeigler CAT of Rochester, Minnesota says that they don't/won't do a re-rate. States that CAT "won't allow us to." Is this common? They sent me next door to Rochester Diesel. They say 100HP for @ $2000 parts/labor. That seems odd. It's a 2000 3126 f650 that started out as a 26' box truck , shortened & now has an f350 box. It's just a big toy I use to tow my 42' travel trailer a couple times a year. Not sure now exactly what to do. I'm just looking for an improvement in fuel economy. Any suggestions?
Hi can you explain the science behind re rating the ECM? I mean what components does the ECM command to work differently?
I have a 2005 lexion combine with C9 engine. It's at 360 hp. Can we safely add more hp? Not driving the snot out of it. Just need a boost once in a while
awesome video, I'm quite interested in hearing more about the tuning end of things with not only Cats but on diesels in general. keep up the good work my friend.
Thank you for the kind words. The tuning on these engines can get pretty intense, but I just wanted to show that there is also a Cat certified alternative to the aftermarket.
i still find it hilarious that you can plug in a computer and load a tune for a 550 or 600 horse C15 onto a motor that originally had 425-435 from the factory. perks of having a Cat versus a Cummins or Detroit lol.
+shortfuse1993 You can do the same with a Cummins or Detroit... js
@@AdeptApe u
Nice moustache
Very nice info. Hey boss, where are you from?. I got 1.3 mill on my pete 379 with cat, c15mxs. Start leaking right next to head. May be you can help me. Can you? Thanks
Great vid
Where is your shop located?
Am scared to time cat engine,pls can you a video of timing of any cat engine
+raymond idirigbe Don't be scared! What engine exactly because they all are different?
THANKS
I have a question;
Can I still add the exhaust, turbo, & Banks power-pack on top of this re-write if I have Cat rebuild my engine?
next valves on cat15 I am waiting
Where did you get the charts for Hp specs
How about if we forget about thePower and focus on the torque that's what makes the engine
Hi I have a few questions , First I have a 2001 Pete 379 with a C-15 6NZ . I am a John Deere Agricultural field tech with 20 years of Deere experience I work with a laptop daily we use a Data link the same as Cat to upload payloads and files . The questions I have are , I am looking at purchasing a laptop and data link with Cat ET installed I want to be able to hook up to my truck and tune the HP , also pull codes when needed and perform diagnostics . I have heard a lot of talk about flashing the ecm and also talk of Mapping the ecm what is the difference , also were can I get these flash files and how will I know which one is the correct one . Are they On cat SIS ? any info would be great Thanks.
+farmerjoe338 The flash file is what sets the horsepower, there really isn't any mapping you can do. You can mess with the FLS and FTS setting, but that requires a factory password. The flash file is also going to require a factory password. The flash file is downloaded from Cat.
Makes total sense Deere does the same thing where you have to be a dealer tech with a password to do things such as this . I am trying to figure out how this guy on UA-cam Steven Bradford ( aka catlepuller ) is getting the horsepower and getting these kitty cats to do what they are doing . I asked him and he said he maps the ECM could you please watch some of his vids and give me your opinion it would be greatly appreciated. Thank you my friend .
where is located the tempeature sensor 2009 cat c15
good morning adept,I want to thanks you for the videos that you have make us,I really learn alot of things from them,pls can you make video for me,a video of how to drup and engine from the a track☺☺
+raymond idirigbe I happily try to take requests, but I'm not exactly sure what video you are asking for?
Adept Ape I think he was trying to say "drop an engine from a truck"
very informative.Thank you.
It can invalidate your wanty ... Engine infirmation tag rough cover front timing cover.
Previous owner had it..
9 to 13 pages.
Go to a cat dealer wanty downloader .. rerate danger.
Corrupted flash file.. does not require any monetary value... Chance that it might damage current ucm....
Which are the the negative to do a rebate on a C7
I just bought freightliner with a C7 and I pull my RV with it and we be honest with you I love my set up but when I’m go uphill The truck struggles a lot will you recommend me to do a rerate basically I need help. I hope you can do that for me and also, if you can recommend me where can I take my truck appreciate it peace.
I have Cat ET at my work. I mostly use it for diagnosing fault codes on C7 Cats in school buses. My dad just bought a 2000 Kenworth with a C-15 6NZ 475 HP engine in it. He is complaining about the lack of pulling power in it compared to his old 3406C. Am I able to rerate his engine for him with my basic Cat ET program? If so, do you think you could make a video of it? Or at least explain where to find it in ET? I don’t work on Cat much, usually Cummins. On a Cummins I would just download a file from QuickServe.
thanks alot
I have a c-15 serial SDP how can I find the chart that you used in this video to see how high I can go with my HP
This is in a 2008 Pete and it had been deleted by 2nd previous owner. Shows 475hp on the computer but KW tech said it could be different HP because it has been deleted is this correct and how can I find out what the HP is?
thank you for your time.
great video
We’re can I get a caterpillar repair systems which contains every system, like SIS which contains every system,ET,factory password,
fantastic vid my freind!! ty!! for this! my 2005 KW! C-15 acert! z model the cat boys around my parts! tell me is junk! well at 800k she's still goin strong! Rto 13SPD and 3.36 rears! She will pass anything on the big road! all day! but at 80 thousand plus I lose a full gear and a split! do you think a rerate would help her? TY From Idaho USA!
+CAT POWER OR BUST! (ALLDAY) A rerate if you are pulling heavy a lot is a good idea. Now it just depends what your current rating is and then seeing if your transmission can handle a bump in torque as well.
3406 and the c15 do we look at the same family ?
Hey I just got a cat 3176 with 350 hp where can I check if can be rétate to a least 400hp if possible thanks
What does this usually cost?
What is the difference between a 3406 and a 3406b cat
ok...why can't my local cat shop update the personality file so it can be turned up to a 550...5ek updated internals 455 stock....
had to recode injectors just to get this paper weight out its own way...lol..even my local repair shop can't get it to take the 550 keeps failing with personality file...
What do u think we'll happen if I but a cat 3406e turbo on a cat3406 b
thank you for the info
Very interesting. Is there a camshaft upgrade from a 2277508 that will allow for more horsepower? Thank you in advance
I have a c13 in a 07 freighter with the smart shift trans I was told we need to have the transmission put in performance mode but none of our cat shops around here have never heard of that would you have any suggestions
Andrew Maas did you ever figure this out???
I said just turn the screw a full turn on the pump
I need to know if fuel additive is needed in a 3406b engine, because of low sulfur fuel, and what do you recommend? Thanks!
How about a motorhome Cummins 8.3L engine, is it the same process?
what about a 2000 cat 3126 with a allison 2000 series
That's a pretty high chance
Could you please do a video about dpf delete
Do you think a cat mechanic is going to tell you how to ruin a cat motor?
How’s it going to ruin it.....🤔
So I'm not very seasoned in this stuff. My question is how this really effects the output of the engine. We've had a couple peterbilts that are twin turbo acert motors. Not sure of the mxs, bxs etc, but one was a factory 475 and the other was 550 from the factory. The 475 was rerated to a 550 but I can say it does not pull like the 550 from the factory. there's a definite difference. Gearing and transmissions are the same. Can you explain why this is? What's the difference mechanically and electronically from the 475 and the 550? It seems whatever they came as from the factory is what they operate best at.
+Justin Hood The twin turbo Cats use the exact same components from 475 to 550. There are differences if you go above that for a heavy haul or RV engine, but you are dealing with the same injectors, valve lash, camshaft, everything. My guess would be the rerated engine has a problem like a boost leak or low fuel pressure.
thanks appreciate the answer
Torque Rating on the Motor could also be different as well. If there is Nothing Wrong with that Motor, then it is the Torque Rating on the Motor. My guess is that The 550 HP Motor is a 1850 Torque and The 475 HP Motor is a 1550/1650 Torque Motor.
I have a couple of questions on rerate 1. when you rerate is there a program that changes to horse power and I don't know what you call it but is like changing from pulling a dry van to a heavy haul? 2. I have the computer and the cat et and also the flash files and password generator programs just not really sure how to use is there a computer program that will break it down step by step on how to use or what can I do to learn this with out having to go to cat school not looking to do this on any other truck but mine
+David lemons I don't really know what you mean about changing to a heavy haul horsepower. The horsepower is just set by the flash file. I don't know of any detailed online Cat training program. Most guys just learn from factory training or from each other. I have a video on how to program an ECM, but it doesn't cover how to rerate. Be careful if you try to rerate as Cat tries to charge a $250 fee for the rerate or else it might lock your engine at idle.
Adept the heavy haul is not an increase in horse power it is settings that is put in ecm to help with the extra weight in heavy haul . If you order a new truck you are ask what you are going to do pull van freight or flat bed or RGN ( heavy haul ) and when they tune the engine at the factory they have different tunes for different applications. I know you can go to a Cat shop and do a rerate and if you ask they will put what they call a heavy haul package in the ecm. I guess what I'm asking is do you have or can you do a list of steps to do a rerate and how to generate and cat password I do have both programs I'm just not real familiar with how to use them yet
I gotcha, I thought you were asking how to change the setting on the horsepower for the engine to heavy haul or light freight. So the heavy haul designation is actually the flash file and typically it's a high horsepower designation. I'm not going to do a video on how to do a rerate yourself, as almost nobody has the tools to do it themselves and it is easy to mess up. My fear is that if you rerate it and then need the factory passwords for a rerate, your engine is going to get stuck in idle only.
adept ok,what is the video are you going to show us
im looking for a pre emission truck and found a pete 379 with a 3406 5ek engine with 550 hp with new platinum overhaul from cat
would that increase in hp damage engine from overheating. its probably a different pistons pack but all that extra heat
what u think ?
What can I do to get more hill pulling power out of my 3208T? It's in a motorhome, pulling hills can be a pain, struggling at 35 mph on some hills.. bigger turbo? Fuel adjustment?
I love that am look forword to see it
