- You should know this if you have a FiTech! These are FiTech tuning tips everyone should know! When I first bought my FiTech, I had to learn a lot of different tips and tricks on how to tune it just right. I want to share those with you.
Buy the FiTech here: amzn.to/2WZBRPv
*NOTE: If you buy a FiTech from Amazon, buy it from FITech, not a third party or FiTech will not be under warranty if something goes wrong*
1. Saving your settings. Every time you make an adjustment on your Fitech controller you need to save your settings. To do this you have to do two things. 1 - click the thumb stick or push “Send to ECU” and 2 - turn the key off and let the numbers zero out. Now whatever change you made is saved.
2. How to get the VRCoil option on the Handheld controller. This is an easy one, but it took me about an hour to figure it out. Go into your handheld controller, and go to Tuning, then Timing control. This is for if you are running a locked out distributor and want FiTech to control your ignition timing. So this is the only function on the controller that I’ve seen like this. You can’t click it, you can’t hit enter and change it, you can only scroll right with the thumb stick.
3. How to get to the "Pro Tuning" screen.
4. IAC Steps. IAC stands for Idle Air Control. So we are going to adjust the air control when the engine is running at idle. To do this there is a screw on the driver’s side of the throttle body. With the engine off, turn this screw in (clockwise) half a turn. With that done turn the key on and go to dashboard and find TPS and make sure it reads zero. And make sure to put your cover sheet on your TPS report. If not, then shut the key off and wait for the numbers to go black then turn the key on again. Once that reads zero start the vehicle and find IAC Steps on dashboard. This number needs to be within 3-10 at warm idle. If the IAC Steps number reads zero then slowly turn the screw OUT (counter clockwise) until the IAC steps reads between 3-10. If the number is above 10 then shut the vehicle off and turn the screw IN and repeat the process until the IAC steps are between 3-10.
5. AFR. AFR stands for Air Fuel Ratio. So this is the air and fuel mixture ratio that is being pushed into the piston. At idle, you want to aim for an AFR between 11.6-14.6. As you drive, the Fitech will learn and balance this number out. BUT, when I go and get my Bronco tested for emissions, I crank this number to 14.9. If you are driving around and always smelling gas, you are probably running to rich and need to increase this number.
6. DFCO and exhaust popping. DFCO stand for Deceleration Fuel Cut off. If you are having issues with the engine popping out of the exhaust when you let out on the throttle. Pro tuning, Rev Limit Decel Cut, DFCO Cut Fuel Map, turn down around 16 and the DFCO return MAP to 18. DFCO Return Fuel is if after you let your foot off the gas and then try to step on it again, and your engine hesitates then you want to bring this number up to around 85. Try different settings on this, and see what fixes your problems.
7. Pedal sensitivity. If your gas pedal has lost some of the sensitivity since installing the FiTech go to Pro Tuning, Accel Pump and all the way down to “dTPS ACC Gain” - the higher you set this number, the more sensitive your pedal will be. If you set it too high every time you hit the gas, your engine’s AFR will drop super low, and you won’t get enough air and you’ll just waste fuel.
I know a lot of you have tweaked your FiTech settings, so leave a comment below if you have a tip to share.

Thank You for your clarity You make the process easier to understand
Very informative, I'm planning on buying one of these systems. Thank you!
Great tips, Thanks! I bought the go efi 8 for my supercharged camaro. I'll have a leg up when I start tuning
Excellent video. I'm in the process of the installation right now and I'll refer back to this for sure. Thanks -
I was a dour to throw my Fitech in the trash till I watched this video!! My IAC was all out of whack and it was a mess! Thank you for good no nonsense videos that help people get in the driver seat and enjoying their ride!!
Thank you have been pulling my hair out til I found this video. Looking forward to getting mine going later today!
Thanks man! This cleared up a lot of small issues I was having.
WOW! You have no idea how much time and frustration you have saved me. I am very grateful for this info. Solved ALL the same issues I was having with my vehicle. God Bless You GREATLY.
Awesome man! Glad I could help!
These videos are the ones I’ve been looking for. Thanks
Thanks for the awesome video.im looking forward to getting one and installing it on my 74 pickup
this video helped alot when i installed my FiTech last year. a year later and about 15k miles its doing great. ty for the great video
You are welcome!
Thank you for the info you don't know how much this means to me. You Rock!
Yes! Cover sheets on all TPS reports, I'll do that working this weekend.
That would be great.
OMG...my decel engine popping was driving me insane with my cut outs open! Thank you , Thank you , Thank you!!!
good video , for people who have never done any efi tuning and are not familiar with fitech it will save them a lot of frustration.
I just got mine running on an 83 chevy 4x4 today. I thank you for these videos. It will be helpful in the future
You bet!
"You want to make sure that you put a cover sheet on your TPS report."
Great video brother!
I got the memo, I just forgot.
What does this mean? I’m not a tuner, so I don’t understand.
@@mlwchevy @3:20 I was quoting him. It's a reference to the movie "Office Space". It's just something funny from a long time ago, nothing to do with tuning. You're just not as old as some of us are yet. It's a great movie, worth watching.
Im 52 but never watched office space. Thank you for answering though
@@mlwchevy You're right, we're almost the same age. My pleasure!
Just installed mine today and that sucker was running rich. Great video, I'll attempt to correct these issues!!
Thanks for posting this. I’m probably a couple weeks away from firing mine up so this is great info to ponder until then. Also... My coworker just got his system up and running and it’s not working right so now I can be his hero...
Haha! Nice!
How could anyone not like this! Smh. Thanks man GREAT VIDEO 👍✌
you are literally the most helpful video know to man on adjusting the fitech.. THANK YOU
Haha! Glad to help
Man thank you for your videos!! I was about to go back to my carburetor because I had no idea how to adjust my efi. Very good stuff!!
Awesome! Glad I could help
Lots of great info, thanks for posting!
Just installed mine on my 403 Toronado engine in my 1978 GMC motorhome.. and now need to Tweek.. This video is very helpful.. thanks..
Happy to help
Thanks! Had the light throttle stutter problem. DFCO return map to 60 and it worked! Was about to drive me nuts until I found your video. Thanks!
+Kahl Buhl nice!!!
but. any more issues?
Between you, Nabors75, and a few others, I figured out why the FItech seemed to hate my Bronco. As of an hour ago, it runs just almost how it's supposed to. Thanks for sharing this information.
Glad I can help
I've watched a few of your videos and it's helping, so thank you. I came out of Nashville, back in 2005, and itching to get back if I can talk these kids into it, lol. We used to live off of Harding Place, I-65 side, near the zoo. We do visit there quite a bit. I've got a Dodge 4x4 here that I built at the shop, where I work, and this FI Tech isn't wanting to cooperate. Bad rich at idle, won't idle. I had it set at one time to where it would idle, but just wouldn't accelerate. The customer was in a hurry to get it back, so I tried to explain to him how to adjust, watch videos, including yours, and drive it around his property, just play with it. Of course, he wasn't happy, and now it's back, worse than ever. I'll keep at it, and thanks again.
Thanks for watching!
Learning a lot here. Keep up the great work!
+pat lucas yeah man you bet!
awesome video, I have been tweaking accel and fast accel trying to eliminate the slight hesitation to no avail, will try the dTPS next, I think there in where it lies.... by far the best Fitech Video so far, from anyone!
+Jabin Trapp thanks man!
i agree
+Jabin Trapp, did you figure it out? Were you having issues at WOT with the non-existent acceleration? I think I'm having a similar issue - at WOT my power drops off big time, almost like there is no fuel pressure.
Jabin Trapp
Nice, good info. I'm about to install this unit.
Yeeeeahhhhh Peter.....Im gonna need you to come in this weekend.
On a serious note....HUGELY helpful. Cool tee shirt btw
😂 thanks man
Awsome👍🏼👍🏼👍🏼 thank you very much very helpful, great work!!!
Great info ,Thank for sharing
Awesome video! You are a great help.
Thanks for the info, I am almost ready to fire up my six pack Fitech set up, I also want to do timing control and I have their ignition box to wire in. My biggest issue is getting my distributer phased using the stock one as I have no space for the ready run or a FI ready distributer...always something, that is what makes it all fun right!!! Thanks again for sharing...
Good luck!
"Holley Fuel Cell EFI Pump Module Assemblies 12-146" is the fuel pump assembly I have in the fuel cell now I will be running a return line for it as well. this also can be found in summit racing.
The TPS cover sheet comment, Amazing!!! This video is Fantastic. Thank you
Haha! You are welcome
What do you mean by cover sheet?
It’s a movie reference.
Great tech Jon!
I appreciate your reply, I actually told the one shop that it was at to put the in line fuel regulator back on it, I was thinking the same thing. Its just getting to much pressure, My car is a 69 GTO , But has a 69 427 Chevy motor in it, (I know all you Pontiac buffs out there I know) , The car has actually been in the shop almost 2 years being restored, During the restoration I replaced the tank with the new Fuel pump in the tank . But I did suggest that, Tomorrow I will mount a in line Fuel Regulator back in the car, I will keep you posted, Thanks !!
i like 68 gto's
and 69
Ok. I havent hooked mines up yet. Keep prolonging. But thanks for the info. Ill b in touch
very good help to configure my fitech
Glad it helped!
Thank you for all your help! I may get one!
This video was great cuz I was scratching my head with some of these
the IAC step tip helped me get the unit started. I think of it as the idle set screw on a carby. Thanks
Yeah. My engine wouldn't even start with the IAC screw at factory settings.
I just got my EFI and called Fitch asking how to adjust for better gas mileage they had me adjust AFR target 1 through 4. 1 went from 13.6 to 14.5 since this is just sitting at idle 2 went from 14 to 14.3 3 went from 14.4 to 15 and 4 went from 13 to 13.5 hopefully this will help with mileage
As always great video!! I am having an issue with my fitech when I shift gears and go back down on the throttle it falls on it’s face for just a couple seconds. Any thoughts?
You just earned a sub because although I'm still not 100% on how it's going to work on my rotary I watched a bunch of videos did a bunch of research and it was mostly good everything bad I saw were people shooting it down because they don't know how to use it because they have never tuned before and so forth buy I have two rx7s one that I've been trying to find efi for so I can tune the shit out of it and another that has literally 0 miles on the engine and Trans and be think the reason we can't get it running after all of this is it might be ported so the afr needs to be tuned but the current carb is tuned out only solutions I can think of are more or larger injectors but I think the fitech may just be my solution because it has a walbro 255 and 790cc injectors and it came with 625cc injectors on the carb
Idk if its for the updated models but at the very bottom theres a "write cal to ecu" and "read cal from ecu" and instead of hoping for luck by turning off your power in dashboard you can "Read" it to save your changes and then go to dashboard and turn off or if you really disliked your tune no worries just go to "write" and all the way at the bottom there different preferences to go back to ur default settings !!!
+jfboosted good tip! What a confusing way to save or delete, read and write. I would have guessed write was how to save your changes and read would be resetting your settings. Good to know, thanks for the tip!
Well I bought my fitech to replace a quick fuel 750 carb. ordered a couple days ago have not received it but started watching the videos. Personally I'm not going to put it on but I will be the one to fine tune it. I dyno''d the car yesterday pitiful hp and torque from the quick fuel carb.. 257 hp 293 lbs torque. Dyno guy said he expected more from moderately built 396.says the timing and AFR are off. Seems like it runs fine to me either way results are awful. I'll post more after it's installed. I do like your videos and plan on using them when I start playing around with fitech
Great post👍👍 I have a 1993 chevy 1500 do you think I could put my Go EFI pump on the stock sending unit and it work just like the stock pump?
Excellent video, thanks
You’re welcome!
Yeeaaah, if you could put a cover sheet on your TPS before setting up your IAC, that would be great.
good stuff. the other guy should check you out he is having many of the issues you discussed. He commented on 5 reasons not to buy FI tech. im stiil with the carbs right now. but you made its eem easy to find solutions... ty
You’re welcome!
That is a lot of thumbs down for how many thankful comments you have. FI conversion is definitely coming to a project near me!
I'm having a case of the Mondays when I try warmed up engine start. 454 w/ LS5 heads FiTech 400 to 1k HP with Fuel pressurized canister, electronic Ignition etc... I'm thinking Fuel prime same as cold start , Timing or expanded Starter Motor?
Great Job
Great info. About to buy for a new engine I’m buyinh
Yeah I’m going to need you to come in on Saturday.
🤣🤣
Just had an issue with go street 400. Hard start, cranking good (or so I thought) took longer than normal to start. Also stumbling after start. Cranking but wouldn't start after sitting about 15 minutes. When it was carbureted would have started. Replaced battery, just touch the key fires right up. Didn't know that the Fitech system required a certain level of voltage to operate. Problem solved lesson learned.
Nice tips.
Great video. Thanks!
Just ordered mine today. Will be putting it on a 70 Chevelle SS 454.
Awesome! Let me know if you have any trouble
great job. thank you
Thanks for making this video.
I had been considering buying a FITech....... now I have more things to consider, first.
P.S. I hate electronics but it's getting unavoidable. For me, just the lingo you use in the video alone , I have to decode, lol.
My motor is being rebuilt right now, I am detuning it a little from high compression down to pump gas friendly, also going from a .800 lift 4/7 swap cam to a .700 lift hydraulic roller cam. still should make close to 800 hp. we will see at dyno time, right now at 572 ci its a little over 900hp on race fuel. it will become a 582 and shooting for between 10.5:1 to 11:1 compression. we will dyno it with the current carburetor then hopefully I will be buying the mean street 800 hp unit. but I have a few questions. the car is wired up to be compliant with NHRA rules with the safety battery disconnect switch then a 4 switch relay system for fuel pump, water pump, ignition msd box, and radiator fan. How would I incorporate those switches? would I wire in the power to the fitech straight from the battery and feed off the ignition key to power the rest of that switch relay assembly or bypass that system altogether and wire up inline relays from the fitech to the individual systems (waterpump, fuel pump, ignition msd box, and radiator fan)?
Does this system work with the HEI distributor? what settings? I have a Ford 302 with the GM style distributor. Iron heads, stock cam, shorty headers.
What would you suggest to adjust to get it to fire up and idle on the first hit
Side note, what do we adjust if the throttle gets stuck closed when i come up to a stop? Then I gotta until I give it a good tap (that makes the truck jump a bit) then I have a smooth throttle, until I completely let off the throttle. Then the process of getting stuck starts all over.
hi
i have fitech 30003 on l6 250
my car is impala 77 with th350
accelration of my car speically wot when car stopped is very low and cant burnout and will slowlly accelrating ...
whats my problem and what do i do ?
tnx
I am wanting to see the real time display still. Thanks
Whatsup man, hopefully you have an answer. I've had the fi tech on my car for over a year now and I just recently switched to ignition control with two wire distributor, now the thing shuts off randomly, I can get about a minute of driving then it just shuts off in an instant, no spit spuddering, kills itself, start it a minute later and she runs for another 30 seconds to a minute. All my wiring looks fine and nothing is loose....any ideas?
I just bought the fitech 30005 and I will be putting it on hopefully today 10/28/23 I'll let you know how everything goes.. I got a small block 355 1990 K5 blazer
Nice
What is the part number for the Edelbrock trigger cable you bought?
VERY GOOD VIDEO MY BROTHER
we installed a Fitech 600 hp system with fuel pump kit. engine started and ran ok but kept setting and oxygen sensor code and a o2 heater code. same as if it was not plugged in. 0130 and 0032 code. you could see on data screen that it was not in fuel control. we called for tech help many times but it seemed like the tech was clueless on what the circuit test and pin out values should be. it would be easy for me to test the system and give them data if I had any reference material. they don't have any available. they told us to box it back up and send back for them to test - repair it. I would have done that if the support wasn't so bad. I fixed it my self in about two hours. I installed a MSD FI that I had in stock. works great.
thanks bro
great video,im thinking of fitting fi-tech go street 400hp system to an aussie hemi 6 with about 320hp.do they work well on an inline 6 manifold,am I better of with with 600hp kit for more tunability,the go street isn't fully tuneable like the others
I would definitely do the 600hp kit. The 400 is cheaper, but the 600 has all the features.
Hey bud tech guy do you have a video on the fan having trouble with my fan settings on and off please help
Hows the Fitect work when it comes to breaking in a new engine
subbed, great info... thanks
Awesome!
I just scrapped my FITech for a Holley Sniper. Done with FITech!!!
I'm about there.. just got my fitech back from repair and the car wont turn over. It tries though
@@overbuiltautomotive1299 huh???
im having an issue for start up idle. its too low start up idle is the same as warn idle. it doesnt seem right. any info for this issue
Umm yeah....I'm going to need you to come in on Saturday...
Really good video, I want to put some sort of throttle body style on my 351c 4V
I was looking at the Sniper, do they have this sort of tune ability or self learning only
+dieholdendie it’s tune-able and has self learning.
I know this is an old video and I’m not really expecting an answer but I have a 351w that has a FITech on it and I can get the TPS to 0 but can’t get the IAC steps lower than 90-120 I’ve backed out that screw all the way and had it all the way in and nothing, it goes from 90-450 I can’t get it lower, any ideas?
Hi , great videos, I wonder if you have had issues with pressure in the fuel tank. I have a 302 and Fitech go street 400 and a fitech FCC.
I have the vent from the FCC, going back to the tank( installed on the filler tube) the gas cap is the vented one ( mustang 1965)
What will happen if the fuel cap will not vent the tank...will the air from the tank put pressure back into the fuel vent on the FCC.
Tony from Denmark.
If you have a vented cap it should be fine. But I’m not running the FCC, I have an inline pump with a return line going from the throttle body. I wonder what happens if the tank doesn’t vent... I’m not sure.
Will it work with supercharged or turbocharged engine?
I’m in Nashville as well !! Would love to get your help with tuning
I thought your supposed to set the iac steps between 3 and 10 with engine warm and at idle?
Once again, great info!
You should do all my videos, which are currently filmed by holding my phone sitting in my basement late at night when I'm really bored LOL
Lets talk DFCO. haha. So the popping caused by dfco is completely normal. You will also see your AFR climb to 20 (very lean) when it's active. Again, normal. But if you don't like the popping, then the only way to stop it is to watch how low your MAP value drops when you come off throttle and start to decelerate. Factory cars also have this feature. But they also have DFCO timing adjustments that prevent the pop. Auto transmissions will typically use a higher Cut MAP and Return MAP value than a manual, unless you have a very high stall convertor. Regardless, if you drop the cut map value down to just at, or below, your typical MAP value reached when you decel, then the popping will lower, or stop. As DFCO simply won't kick in as often, if at all. However, always keep the DFCO Return MAP value about 2 above the cut MAP. The Return MAP is the MAP value at which the injectors start firing again. If you find it's a bit too lean coming out of DFCO, then increase the DFCO Return Fuel value. This value adjusts how much fuel is being added when coming out of DFCO.
For special note on those with manual transmissions. Many of the users I've helped with a manual, have had issues with stalling at low rpm or coming to a stop and engaging the clutch. This is due to DFCO going active, but not coming out of DFCO fast enough (Return MAP value too high). This is why for manual trans users, I typically recommend either disable it (set cut map to >5) or set it very low. Cut MAP 16, and Return MAP 18 are usually good starting values for manual transmissions.
+Nabors75 you are a genius! If I’m ever close to you with my Bronco I’ll come shoot some videos 👍🏼 thank YOU for the info
Anytime. Thank you for the videos. I'm sure it will help many users.
As for my neck of the woods. Drive north for about 30 hours and you'll be close ;)
+Nabors75 haha! One day
Great video. Where did you find all of this info? Their website leaves a good bit to be desired. Would you happen to have a list of the fault codes for their system? I'm showing a Fault 1 as 74 (2 Barrel System), and can't find any such info on their website.
Thanks! I’ve just gathered this info as I’ve learned the unit and as I’ve tried to get mine running better. Unfortunately I don’t know any fault codes.
That's the thing about these efi in a box kits. They make it sound like the system will tune itself. While it may be able to make the engine run its going to take at least a modest amount of tweaking as well as the associated knowledge to accomplish said tweak to make the engine run well.
+Do R/C! Haha so true
Bronco bumpers
Too many configurations to get an initial setup tune work on all of them
Wow excellent video. I’ve followed all the steps but I still can’t find a menu to adjust my timing curve. Is it hidden somewhere in the Pro options? Thanks for any advice.
The menu has probably changed at this point and I don’t have mine anymore
my problem is I cant get my engine temp below 219 or to stabilize I have a 545 (460) stroked a 871 blower and the dual power adder system I have a 35 gph elec water pump a 4 core aluminum radiator I tried a 180 stat a 160 stat I am switching to a restrictor instead of a stat and going to a 18 inch shrouded fan I have set my afr to 12:1 and my initial pump shot to 159 from 259 I have set the base timing anywhere from 10 to 25 '
Mine runs great at idel and once I start driving and get to 3,000 rpm it starts spitting and sputtering like it's misfiring. Any suggestions would be much appreciated
Fought my fitech for 5 months to find out the ECU was bad. Now it runs much better but still has a stumble at start up at times 4 speed. Noticed it when it idles for some time at a light, if I give it some gas first it doesnt do it. The AFR too low? it ides too rich. Thank you for a great video.
+Tim Neal could idle too right, but I️ think it’s probably dumping too much fuel at take off. There’s a guy on here that talks about it. Nabors75 I️ think is his name
i just forget buying me one
I have been messing with this thing for a week, Its now at the second shop trying to get it to stop dumping fuel into the system, I cant seem to get it to lean out, I am on my 3 rd set of plugs and second oil change in a garage, I have talked to Cust Service, Depending who you get determines your level of help. If I had it to do over I would have never bought it, Big Block 427 , Still to this day, I have not driven car 3 weeks !!!!!!!!!!! However I think this video could shed some light on things THANKS !!!
Man! That’s a bummer! Hopefully it gets worked out
Check the pressure on your fuel regulator. I had a similar issue with it fouling my plugs and running too rich even with adjustment. Come to find out It was a bad fuel pressure regulator. It should be running at 58 PSI. Mine was running at 90 flooding the TB and intake. Swapped out the regulator and the truck has been running like a dream.
im sorry. trust the carb man
i mean. whats wrong with a little cold start . if the automatic choke is adjusted right it will warm up, then its ready. we just gettin more impatient i think
Need updated software for ecu, that solved my fouling plugs over and over
great video
Thanks!
Hello my friend, how are you? I am from Brazil and would like to ask a question ... I installed FiTech in my Ford Maverick equipped with a SBF 302 with a Stroker 331 kit and I am having an annoying problem of solving during engine starting. He just does not turn on the first match. I have to turn the ignition key on and off 2 to 3 times before it works. Did you go through that? Would you help me? Thank you in advance !!
+Felipe Pessanha de Sá hey! I haven’t heard of that problem before. Have you checked to make sure you are getting 12 volts the first time you turn your key on? I would check for that and check your ignition switch. It could be going out
Actually a lot of good info on here. The old LA 360 is getting tired in the '80 Powerwagon. Currently running a Carter Compation Series carb., with manual choke. How sensitive is the FiTech to temperature changes. Live in central Alberta Canada. We often see 10 to 20*C difference overnight. Planning to install a '99 Magnum 360, with a Crosswind intake, to eliminate the factory beer keg intake that the '99 has.
I haven’t notice the fitech having issues in the cold. But the lowest I’ve driven is in 4 degree weather
That's pretty much average up in Red Deer. My daily driver is a 99 Ram 1500, and I wasn't sure how an after market fuel injection kit would compare to a factory fuel injected set up. I'm thinking this set up is basically the old throttle body injection system, but now programmable.
Vary Informatived ... Great J o b
