Help with ECU install

jhollywood · Apr 23, 2011

I have recently turbo'd my car and I am trying to run a socketed P28 ECU for my set up and I cant get the car to run right off of it. I have upgraded my fuel pump to a 255 LPH and also upgraded my injectors to 550 cc injectors and fuel rail to AEM high volume fuel rail. I also have a tommi fuel pressure regulator.
When I hook up the ECU the car will run super lean and then die out. I have tried turning the fuel pressure up as high as it can go but it wont richen up and ends up stalling out.
any thoughts, idea's or help would be greatly appreciated.

are you running a basemap?

jhollywood · Apr 23, 2011

Yes, I have 2 separate chips set up,neither one will make the car idle. one is set for a stock setup and one is set for a boosted setup running the 550s and both are tuned for the stock map sensor

did you do the 2 wire iacv conversion?

jhollywood · Apr 23, 2011

no i dont :doh:

that will help keep the car running atleast,wont be perfect but still
You wont be able to fix the lean/richness until its tuned by a professional. I suggest you make an appointment and get that done ASAP.

edit and also you wasted money on the fuel rail and stuff..i believe ours can handle/support 500hp.

well thats good to know about the rail and injectors ill have some spares in case these go just a pain swapin them all back.what year make and model also engine can i rob the 2 wire iacv from just so i can hopefully finish this up. thanks again for the help

the injectors i think are 250/300hp max..Im making 217whp on my factory injectors but have 440cc precisions in my closet waiting to go on.
and i belive the f22 accords have them. also need the blacktrax adapter plate.
or can swap the entire manifold over(but cant remember what one) but then some re-wiring needs to be done at the iacv and ecu..only 2/3 members have successfully done the swap at my knowledge

wasnt the f22 in like the 97 accords if so than i got one. so i just gotta make the plate now and figure the wires out should b easy 2 do at the shop i hope. yeah i get to play with the plasma cutter
