Ok to make a long story short here we go:

my car was running uberdata until I got it stolen and now I got it back but my chipped ECU was not the one plugged in the OBDI connector, it was a virgin P28 hence a civic SI (EX in USA) ECU my engine is a b18b1 with 450cc injectors, so I tried to start up the car with my Uberdata ECU hooked up and it was running soooooo rich the car barely Idle and rheres was black smoke coming out the tail pipe and from the engine bay. so I tried the virgin P28 and it idled just fine I really dont understand how a P28 ecu could idle fine some 450cc!?!? I also found a manual of an VAFC on the passenger side. but I dont find the VAFC unit, IVe checked for an FMU as well but didn't it,,,,, how can this be possible. I dont have any cells cause the dash isnt working properly . any inputs would be really appreciated.

TIA

 

ttt please I need some inputs

 

I'm no expert, but have you tried resetting your ECU? Is it possible the virgin P28 could have 'learned' the 450's and set the LTFT to the point where it can run them?

 

both ECUs were unplugged for like a month so they had plenty of time to reseted themselves thank you,,, anyone else??

 

up

 

help needed desperatly
