Civic turbo problems.. runs rich no matter what..

Update on trying to find a solution to my problem..

[@jayalves2634]

Check for a short in injector harness, the short can cause your injector to be stuck on on one of the injectors

[@civicpride1986]

jay alves i am going to try a different harness from one of a friends car and will see.. thats next..

[@teizparker9091]

I’m literally having the same exact problems man, stock b20 turbo with 750cc. Replaced everything you named. Really leaning towards harness but I wouldn’t know why all of a sudden. Hope we can figure this out bud. Keep us updated please

[@civicpride1986]

Teiz Parker i sure will, i just weird..

[@luiscamacho9220]

Im having the same issue. Almost identical set up. Mine runs at @12.5 at idle to. I wired my wideband to the s300 and tried closed loop and it idled at stoich but didnt want to drive it like that. Im lost to. Keep us posted.

[@Kizortv]

Good luck man, I feel you on the stress

[@justbecause2010]

Man I feel your pain. Running two points richer no matter what. Did everything I could possibly think of and I’m in the hole. Same exact thing with me. Idk what else to do either

[@civicpride1986]

Is a strange issue that other people have experience... I was never able to find the cause..

[@justbecause2010]

Damn man I’m going on two months, new o2 sensor, new plugs, new hpfp, new injectors. Gonna do a smoke test and boost test. IDK what to do lol

[@civicpride1986]

@@justbecause2010 I only have that problem at idle.. while driving my air fuels are normal.. so I stop looking into it.. car made great power after the tune.. I try so many things I fix that rich situation that I gave up on it..

I really think it’s the throttle position sensor or my dirty ass valves lol both are getting taken care of very soon if not I’m seriously throwing the car away lol

Trying replacing ur sensor or possibly check a ground in ur engine bay or try replacing ur main relay hope u figure it out man and check ur fuel return and check ur fuel pressure regulator

[@civicpride1986]

boostingLS !! I will check the grounds again and see of that does anything.. main relay dosnt sound like its bad but i can try a different one and see what happens..

[@gsrturbo3786]

Do a resistance check on the ect rule.it out. Ect does effect fuel trims.

i try a different distributor and did the samething.. but i can check the voltage going to it and see what it reads.

Hook your wideband to the ecu so it can be dataloged

[@manubinsia1101]

luck for me not the injector but mines is always iacv been thrown check engine light...using greddy 550cc injector...

[@EverythingBoost]

I had the same problem with fic 1600cc injectors but found out that they were low impedance injectors so I had to put a resistor box in my EG Civic to fix the problem or you can buy new injectors but for high resistance because that's what the OBD1 harnessed is

[@civicpride1986]

I try different set of injectors even oem set with stock computer and same issue.. it something else.. my grams 1150cc injectors are high resistance..

[@OnlyBuiltOnce]

Have u gapped the plugs closer an reset the ignition timing in the hondata settings? Disable sensors you won't be using an go from their.

[@civicpride1986]

Brett Padilla yes i reset timing and install new plugs and gaps them.. whatever it is has to be in the tune.. something with the coolant temperature correction or something like that.. car will drive but after a few minutes i will foul the plugs and car will hesitate and bog... Driving it stays in the low 12s air fuel.

[@OnlyBuiltOnce]

civicpride1986 are u running just one of the preload maps from hondata?

[@civicpride1986]

Brett Padilla no, i try 2 previews tunes from where i got tune.. both tunes very similar to what the motor is now.. one at 408whp and the other at 445whp.. i did try the stock hondata map for a LS and did the samething.. goes rich

[@slverbuet1791]

Yo bro I really hope you figured this out its nothing to do with any parts in the car just because your uploading a Hondata base map dont matter the car NEEDS TO BE TUNED that's the only problem the base maps are just that a base to start your tune they are far from perfect get the car tuned if you have Hondata go to the fuel Map and pull 20% at idle

[@civicpride1986]

I did all that and nothing solve the issue, even after tuning it would idle rich.. but once driving its fine.. been driving it like that no problems.. car made 602whp at 32psi.

[@brandon2065]

S!lver Bu!!et I pulled 35% and it barely changed the AF. Not sure what it can be. I’ve replaced parts the tune is spot on. It ran perfect and then the next day it just started running rich and now I can’t fix it. Any idea?

[@SIRICKO]

Bad o2 sensor my man.

[@civicpride1986]

SI RICKO i am open loop tune, is not using the 02 sensor at all.. the aem wideband cant be bad, car drives as if its burning this much fuel and the smoke.. is definitely not the wideband..

[@SIRICKO]

civicpride1986 that’s crazy my man. See this is y u need to make a Facebook lol and join my Honda bays group, you would have been hit then right answer.

[@civicpride1986]

SI RICKO post my video and see what they say.. i check online everywhere.. i am running low on ideas.. replacing the engine harness is my next move

[@EbayTurbo]

SI RICKO that's exactly what I was thinking

[@FroztiProductions]

my boosted stock d16 is doing the same thing. Driving home one day and pegged rich, idle and part throttle 9-11afr, and boost would go lean. It's so bizarre. Changed injectors, calibrated and changed wideband, gapped plugs, new plugs, new dizzy, tested map/tps/iat, tested fuel pressure with external gauge. I wanna borrow another ECU and put my tune on to test. Did you fix it?

[@civicpride1986]

It was never fix.. mine was only rich at idle.. while driving the air fuel was fine so I left it alone.. I got tired if chasing that down and never finding the problem.

[@FroztiProductions]

@@civicpride1986 Mine went completely fucking wacked in an instant lol so rich I could shift hella fast cuz clutch in rpm would drop like a light weight flywheel. I'll figure it out some day.

Did you ever figure anything out?

[@FroztiProductions]

@dallasjackson3404 I got a new ecu, soldered it all myself then put my hondata in it and it worked fine. Still needed to be tuned a little but worked.

[@ekelo]

just had to get tuned

[@brandon2065]

Did you figure it out? My gsr is doing the same. But as soon as I start the car it tries to idle in the 9 which is too rich. I’ve changed most of what you’ve changed and can’t seem to get it. I tried taking fuel out to lean it out and I have to take way to much fuel just to get it to idle where it needs to be.

[@civicpride1986]

Sadly no I was never able to get it right in the air fuel while at idle, I got the car tune and while driving is fine perfect air fuel, but at idle it would go rich, tuner said it was my injectors, but I told him no because I try different sets and they all do the same even a stock oem set on a stock map would do that..

[@brandon2065]

That’s just a weird problem man! So far I’ve only seen a gsr do this. I’d say do a compression test but it’d be pointless if you made 600+ on 32 psi with no smoke or issues.

[@civicpride1986]

@@brandon2065 yea is not engine related, the only thing I never change was the dash harness that goes into the ECU and alll of the dash maybe there was a shortage somewhere causing that at idle.. but since driving the air fuel stay normal I stop looking into what could be the issue at idle..

[@brandon2065]

After you it a retune did the car run smooth? Mine currently bogs out while driving, and get way to rich while at idle when I turn the car on. I’ve went and adjusted the timing and changed the fuel tables and nothing seems to work for me. I’ve tried multiple different basemaps, old tunes, and I still have the two slightest annoying problems. I think maybe it can be in my wiring harness but I’m not sure. I tried a new ecu and it isn’t working. I doubt it can be my s300 chip itself.

No i did everything i possibly could to fix that and nothing work.. i did got it tune as is and while driving air/fuel is spot on.. but idle air fuel was not perfect still on the rich side.. but under boost and while driving everything was good and made good power so i left it as is..

@@civicpride1986 turbos run very rich on idle

[@brandon2065]

Yeah my low cam fuel tables was off a lot somehow. So it’s kinda fixed. I have a electrical issue that somehow changes the af. It’s weird but when I turn my headlights off my af is around 11.7 at idle and when I turn them on my af is in the 14’s for idle. It’s so weird!

[@civicpride1986]

Mine also did that when I turn my headlights at idle that would affect my ad readings.. reason why I upgraded my alternator to a higher output one and that did not fix the issue.. but at least I ended up with a new and nicer alternator.. after changing so much with my car I ended up just blaming it to a shortage somewhere in the dash harness, that's the only thing I did not change..

[@brandon2065]

Does your headlights still change your readings? If not how did you fix it if you fixed it? I thought it was the alternator or battery. I'm also thinking maybe the wiring harness may have a short in one of the wires but I'm not sure. Its hard to tell when its electrical.
