FMU and p28 boggin help
i know fmu's are gay, but i just need my setup to run properly right now.
stock injectors
5.5psi boost
fmu 12:1
fpr
when i use my stock p28 it bogs in boost, and goes into limp mode. if i use my factory obd2b ecu its fine, but it leans out alot when its warm.
any ideas on the p28? i tried the check valve on the map sensor, and still no luck. missing link maybe?
it fine with my factory ecu under boost, just real lean!!!
thanks guys

Re: FMU and p28 boggin help (MB4mang)
if it is goin into limp mode, you probably have a check valve issue. i tried the fish valves with my setup i had before, and the missing link worked much better. try a missing link, and when you can, switch up to decent engine management. i had the fmu for 2 years, no problems, but you can get so much more power out of the setup you already have just in tuning.

Re: FMU and p28 boggin help (boostedcivicsir)
yea, i found out i had the check valves hooked up wrong, so the map sensor is good to go now.
my friends install the fmu the wrong way. the pressure side, and the outlet side to the tank. they put it the other way around. so now i think the fmu is fucked up.
has this happened to anyone? fmu gotta be replaced? or should be ok... thanks
