Guess what my 409,000 Mile M5 made. Oh and what's Gregs car worth?
342 rwhp, 47k$
338whp, 60k
305 hp and his car is worth whatever Carmax will give.lol
About 350 Whp, And Ask Hoovie, he will overpay :P
320rwhp and his car is worth $39k
I fkn love OJ man the man knows his stuff looking forward to the 400k Dyno run
Want to hear what Greg has to say after he drove his NEW M5.
Man I wish you could've added Greg's reaction to driving his car with the extra horsepower.
Was waiting for just this. Such a letdown
Greg hasn’t been seen in days. By tracing his credit card charges at gas stations we can se he has been making his way toward Germany for a blast on the autobahn.
Seriously, I’m totally stoked. It’s like the car I always dreamed it should be after seeing the BMW Guy Ritchie movie-ads when the car was new.
I wrote a song for OJ as well.
Having not noticed that he only had 200 horses for the last 3 years, I doubt he actually drove it any differently AFTER the tune either: how could you not notice your M5 was pumping out less power than a Golf GTi?
Orfan Productions when you look at the torque pre tune it was around 260-280 in the 2000-3000 range which was not terribly far from the tube torque in that range. If he was using it as a cruiser/weekend car it probably didn’t feel off in that lower rpm range which probably masked the problem.
I was really hoping we would get his initial impressions too.
@@johnbcardin Are you seriously trying to make excuses for this? That in 3 years of ownership - cruiser/weekend car or not - he never once accelerated past 2/3000 rpm? Yeah, ok man, you're right: it actually is totally understandable that he had no idea his car was 40% down on power the whole time.
Great video mate. I love the old school BMWs.
I own a few BMWs (e38 740i&e39 530i) myself and currently doing some major work on my E38 740i.
I would love to own an E39 M5, this has been my dream car since I was a child.
Very educational video. Keep up the good work.
These guys are akin to physicians diagnosing and treating a human ailment. Their knowledge and skills seem amazing!
Reaction video on the gain?!?! :D
Rasmus Werner Eliasson this please
OJ is what an excellent mechanic should be. Damn he's the man, props to him great job
Alex Always a pleasure to watch you go to your special place with these cars. This will educate lots of owners.
As a Pro Detailer, I know Jason at Chicago Auto Pro's where he works at. Also do I see a dual head rear laser jammers over the rear plate?
We soooo needed to see that guy drive it.
OJ is the MVP!
OJ, OJ, OJ. One sharp dude.
OJ is scary genius! That guy looks and sounds crazy smart way too smart for me to understand? LOL
OJ is a total bad ass!!
Oj is a BMW GOD.
Excellent vids mate keep it up !
Well it means that this m5 has a 420 or 430whp if on a jet dyno wich mean on crank it has around 500hp well done but i wonder if i could get help i own a bmw x5 4.8is tune by dim sport can i modifie the tune by deleting the air mass flow ? And how will the ecu reads the air fuel ratio?
Looking forward to some more M5 action
Had a bad MAF on my 2.5 323ci....replaced it and had starting issues ever since. Got rid of the car as I was tired of spending 500+ every 4-5 months. I simply don't have the money to keep repairing one of these pieces of crap, even though I can do most of it myself.
Every time my friends get in my car 13:24
If you’re in a garage and you can’t see Brake Clean bottles wherever you’re looking - you’re not in a real garage.
Is that a gtr in the back? I saw it around naperville a few times 🤯 anyways, dope video!
Your in Naperville im in Aurora 💪🏾
Gotta try this on my VW.
I miss my 99 540i M Sport, mine also had the automatic transmission which I was told was rare
The oil rings weren't too happy with all that.
Time for a new plate OMJ5
Why does smoke come out near end of each pull?
What was his reaction to the car after being fixed ?
Show us his driving now!
Yeah....
those wheels man.. MM - MMM!
Buys M5, has no idea what a 200hp car feels like vs 350hp....
nice to see professionals actually fixing/improving cars, not just talking about it.
These two are the best :)
thats why we love LSC channel :D
E39 Guy here. Now this channel really is legit.
Same here! I have a carbon black 2003
We have a stable of e39s. Best chassis in my opinion.
That guy is the BMW Whisperer. He predicted what was going to happen before it actually happened every time. I wish I lived near to him.
Mad respect to OJ and techs with this kind of brain.
Thank you!
Brian, Alex, I just watched this vid again cuz' I couldn't remember what was in it the first time I saw it. I literally got up out of my chair and genuflected to OJ as he made the last run. One of the best vids you have made! Bravo, bravo!
Hoovies garage and his anemic e63 AMG needs to see this!
Make an addendum with him driving it, so we can see his reaction to 139 hp increase.
I kept telling mechanics that my car was sluggish. Their response? "Oh hehehe you're just used to the power so it doesn't feel as fast."🙄😒
Great to see someone who knows what they are doing.
When they said, “It’s like you’ve been driving a 540i!” Hahaha only hurt a little bit, I’m okay. 😂😭
I felt attacked
I've had an e39 540i 6spd for 15 yrs. That comment hurt my soul.
Good news is, I pick up my e39 M5 tomorrow
The first thing i would have done by such weak performance: air filter check, cleaning the needle in the air mass sensor with break cleaner, check the sparks, run the car with injection cleaner addtitive reset the ECU and teach them new.
You must have done this so many times. But next time, if you use brake cleaner, first make sure you look at the big words on the front of the can. Then you`ll know you`ve picked up the right can. Don`t ever use break cleaner. That`s terrible stuff.
@@pauljoe780 The small needle in the air flow sensor can only be cleaned with hard chemicals and break cleaner is perfect for this, you dont need much, just a short spay and after soaking a second. It´s just about get rid of the dirt film.
Alex, thank you for bringing us some M5 content. I'm a AMG person myself but I've always loved the E39 M5 😍
No word of a lie, my M5 had an Alpha N tune already but it generally was sluggish and very lacklustre to drive, even after fitting a 3.62 rear end. However once I'd done the IAT relocate mod and disconnected the MAFs, it genuinely started to come alive. It was improved for sure, but at the back of my mind, I thought maybe the cam sensors needed changing or something. But then today I wanted to replace my steering wheel, so I inadvertently reset the adaptations by disconnecting the battery. When I went for a drive in the evening, holy moly it really was a spectacular night and day difference. First gear is a blur and second gear gives me such a shove back in the seat that it brings a huge grin to my face. I wouldn't be surprised if my M5 showed similar gains on the dyno like this car here too.
A tune? The car is tuned from the factory, this is a modification. Why not replace the bad MAF's and do things properly rather than running the car with bad MAF's and an ECU modification?
Is that your car? No? Then shut the fuck up.
My 01' 530i sport is sitting outside waiting for me to tinker with its MAF... I'll be back
0:51 Wingless GT3 RS...It’s Beautiful without the wing😍
Thumbnail says "Try this one trick, it only takes 10 seconds" then I open the video and it's a 16+ minute video 🤭🤣 Great video though 👍
It's nice to take your car to someone who actually knows what there talking about
Great video just wish they would tighten those rear straps, waaaaay too much movement and slack in the rear. It’s coming off of the rear roller
I normally don't hit the like button on UA-cam. But I gotta say, this was cool. Well deserved the like. That's what experience looks like. Good Job, OJ.
....? And why not hit the like button on UA-cam?
Lenwood Cruze he’s a bitter and doesn’t like to support anyone
We need his reaction of driving the car ..would've been awesome to see what he thinks after gettin that much power back !
Coming from a lexus guy,
your bmw engine sounds beautiful
OH BABY................... It's like having a cute but slightly chubby girlfriend losing that weight and then getting really fit and toned.
Dude that so fucking shallow, what a douche. For real, you really rethink your life.
Tracey Allen nobody’s going to fuck you for saying that🤣 it’s an analogy/comparison grow a pair
No, it's nothing like that, you dipshit.
But you must remember she's never truly going to be yours it's just your turn
Then she dumps your shallow ass
My E39 M5 made the same 343WHP on the same dyno (DynoDynamics) with Alpha-N. Besides tune and rear mufflers my car is bone stock too. Great video proving the point of this channel once again: enthusiasts over stealers!
good to hear the feedback since people seem to dislike our dyno numbers!
oahgfojsdljknsdlfw Around 88k miles.
Amazing! Love the consistency.
The E39 M5 is definitely one of the best BMWs ever made
it is the best
Some say it's the last good one.
2003 m5 was the best bmw other than 2004 330xi 2001 740il. 2000 m3
I've got an E39 540 msport and an M5.. Best two cars ever..
@@gorrington007 yo that's cool
Why not try swap swapping the mass airflow meters from your car?
Hahaha! “You’re gonna drive easy, right?” “NO!”
That's pretty awesome. You basically re-found about 75% more horsepower. That being said, that's one thing I both love and hate about the complicated electronics these days. You have to be an electrical engineer to diagnose and fix modern vehicles...
“Takes 10 seconds” uploads 16:36 long video
This is one of the most joyful videos I have watched for a long time. I truly hope people recognize what a master OJ is and take their business to him. It would have been nice to see what, if any difference cleaning the MAF sensors made before the delete and tune.
"...joyful..." I second that motion!!! Got misty-eyed watching the great camaraderie between all three of them!
I wish I could get my e39 m5 serviced by OJ! I'm legitimately thinking of driving my m5 to Chicago from LA. 😂
Loved seeing this I wonder what Gregg’s reaction on the road. Just shows like you said how important it is having a tune now and then.
I’d say yours with mods 300, and his cars worth approx $20,000?
the hp gains brought a tear to my eye 😢. this was a beautiful day
that dude didn't use his resources at all in the 3 years of ownership he didn't bother to look up one BMW dyno or watch a single M5 pull on UA-cam blows my mind
Yeah, not to be negative to the owner, but he could have had a 530i and never known the difference it seems. I am happy for him though.
In his defense, butt-dynos are notoriously unreliable, pretty much the only way even for an experiance driver to feel if your car is 100% with no comparison vehicle at hand is to take it to a dyno or the dragstrip/time it 60-130 with a stopwatch,
I always knew the car wasn’t right. I’m not a mechanic though so I rely on them to tell me what the problem is. The car has been to three different guys I trust with my other cars. One of them was a BMW specialist recommended to me by other E39 owners. Nobody could do what OJ did so easily and it’s not that I was afraid to spend money on it. Basically it’s a combination of OJ being good at what he does plus the others not having the deep BMW experience he has. Let’s face it, diagnosis is a skill that not many have and if there isn’t a code to tell you what to do...
@@gregnatonson6970 I apologize, It does say in the video you never felt the car was running as it should. Still, even if the other guys could not find the fault, they should have been able to spot something wrong with it, a timed 60-130mph run is easily done and would have taken twice as long as stock, when the normal variation is only in the single digit percentage. They would have known and performed this so they could at least tell you something is wrong even if they could not fix it, just a professional courtesy. Bottom line: You were a bit to trusting, it happens. Great that you finally got it fixed.
Very few people dyno their cars it’s expensive 😯
Haha Greg's M5 had a lazy life till that day
So , they didnt replace the bad MAFs? But tuned them out? How can this be good? Explain!
Tuning is all electronic and ecu based. No true effect on the physical parts. It’s just telling the car through the computer to run, open, close, allow more or less fuel or air or whatever to happen.
We explain everything in depth in our new blog post. Check it out here www.fluidmotorunion.com/what-the-hell-is-alpha-n-tuning/
Title is deceiving! They made it sound like they gained 139 hp over stock 400hp by simple tuning! No way. Engine has a problem and not producing the proper power that it should. Come onnn writers!!!!! Ughhh!!
Hey Alex great video, wich adaption did oj reset? He said the ecu... But I can't find any way to reset the ecu with the bmw inpa software. Only mass air flow or lambda... Could you please explain what exactly he did? Maybe you could do a video with oj .. 😉
Not a BMW or Merc, but I had a faulty DPFE EGR sensor that didn't throw a code on a Ford. Always thought it didn't feel right power wise and boy was I right. Massive difference in power and MPG when I changed out that sensor.
man what a classy shop, grade A quality, skill, and knowledge
"I'm gonna go home today, and my family is gonna write a song about you, and we will sing it" lmao
I teared up when I heard that... Wow, that was priceless!
Since he doesn't need the MAF any longer, could he remove them to allow better air flow and gain some more power?
theplayernkc they add 0 to no resistance so I don’t think it will make a difference tbh
The MAFs are not the restriction on this engine. The tiny headers restrict more power than anything else. Quality headers are worth 30-40 whp.
@@KurumaDesigns All the MAF sensors I have seen have a protective mesh screen on them. That has to be affecting the amount of air getting pulled into the engine, plus the sensor itself being right in the middle of the airflow. So I see them as restricting airflow and causing turbulence in the airflow.
@@theplayernkc if experts and the engineers behind them don't consider them a problem leave them there, no need tinkering with smth that doesn't affect anything
@@95freakout What experts and engineers said to leave an item in the intake system that obstructs the airflow when it's no longer needed to be in the intake system for the vehicle to run, especially when there are 2 of them?
No MAF AND 139 more ponies with a tune? Nice!!
OJ is awesome, you 2 fit together perfectly 💪
PS: But AMG is still BOSS 😋
There are a few cars that you just can’t see past; cars like the W204 C63 and E39 M5. No matter which team you’re running for, those can’t be hated. They stand on their own - no matter a Merc or BMW badge.
J Gripen sure m8, just a little joke 💪
Well OJ has a new customer for life! Love it when OJ is in the vids!!
Show us reaction video with his first ride after the dyno session! Please
Everybody out there that thinks he is a mechanic just watch this video and be quiet!!!!! :)
What kinda idiot can't tell their M5 is underpowered?!!!
BMW? Quick fix...match and lighter fluid
What about the White smoke during the hightower dyno runs?
It's running rich in the high rpm and high load conditions, for safety and maximum power. Running rich produces a bit of smoke from unburned fuel.
For all of you who have questions about what Alpha N is and how we use it to tune check out our blog post! www.fluidmotorunion.com/what-the-hell-is-alpha-n-tuning/
LSC: _"You need a O. J."_
The Goldman family: 🤔🤬
I'm just sayin'......
16:16 after deleting Mercedes part the bmw runs better 😂🇩🇪🛠⚙️🔩
10 second tricks takes 15 minutes to video LOL
Does anyone know what are those Windows Mobile phones used for in 7:30 ???
Those are our wireless controllers for the dyno!
@legitstreetcars would these adjustments effect the E46 M3 too? I had maf running rich issues and assuming they were made in the same year
Its definitely possible! Try unplugging them and see if it runs any better.
Can we disconnect also the airmass flow sensor to m42 b18 engine with bosch airmass flow to produce more power?
The reason it produced more power is because the MAF was not working properly. So if your MAF is functioning as it should and you arent tuning the car to run without it then there wouldn't be any gains. Check out our blog post here to find out more info on mafless tuning and the alpha n tables www.fluidmotorunion.com/what-the-hell-is-alpha-n-tuning/
So no MASS or MAP sensors tuned via dead reckoning.
My question is how does it compensate for altitude change?
My question is, how does it compensate for anything, especially airflow, without airflow meters?
If it knows throttle position and engine RPM, then it can mostly figure out the airflow as it'll be a fairly fixed relationship (that's how it can keep running OK without the MAF sensor). It knows intake temperature too, so can compensate for the air temperature, but if it doesn't know air pressure then it doesn't actually know how dense that air is, so how much oxygen it's getting in. It can guess sea level, or it could be tuned for whatever altitude the rolling road is at, but like Roger said I don't see how it can compensate for altitude and not get rich one it's up a mountain somewhere and getting less air than it thinks, or lean down at sea level.
Cars with a MAP sensor are measuring the pressure in the manifold, so that's compensating for altitude automatically (if you know pressure and temperature in the manifold and RPM you can figure out how much Oxygen is going into the cylinders).
@@AJB1 Thank you for the great break down.
@@V8slayer @AJB nailed that explanation. If you want an even more in depth look check out our blog post on it www.fluidmotorunion.com/what-the-hell-is-alpha-n-tuning/
That's just sick. OJ is the M5 Man. Great vid.
I would have liked to see a before and after with him driving it and his reaction to the tune
409,000 miles?! 409,000 miles?! Great Scott?! Are we talking about the body or the engine? I really dont belive it
I had one with 4500000km
@@ddbb8802 maybe it might have been possible for engines pre 1996 but after that no way. BMW and their plastic minded engineering have made sure all engine never reach 100k with out problems. By the way what car do you have that made it up that high?
It was a e39 m5 99. I blow it at 47k in a traffic circel while drifting.
So what else is wrong with his cream puff? 342hp with a tune? 2005 M5 bone stock claims 395hp 24% drivetrain loss would put it at 302hp so an e39 with 100,000 miles has the same drivetrain loss as an e39 with 400,000 miles... I couldn't imagine paying for a tune and only getting 24hp.
The dyno guy is the bomb!
Thanks!
I want part 2 rn asap
Same sort of thing with the Land Rover Td5 in that the MAF will go bad but not throw a MIL, plug in a Nanacom Evolution or similar and it’ll throw a MAF value low error in the log but otherwise there’s no outward sign on the dash to indicate failure. Disconnecting the MAF will lead to a small increase in power but prevents the overboost function working correctly. The Nanocom at least will show you the air flow values and with 2 out of the 3 in the fleet showing zero it was time to replace a few MAF!
Is it just me but don't the tuner look like Kid from "Kid & Play"... IJS!!!👀👀👀
One of the best vid's done thus far, just awesome. Would have nailed it if a real life drive with the owner was done for comparision.
This man OJ is a jam to listen to, and thanx to you Alex for featuring him every time, im now subbed for he's channel, but your collabs (here in LSC channel are better).
