I have a problem with my car. it was acting up the other day with a fuel issue. I took it to the dealer yesterday and they said that it is loading up on too much fuel. they put the stock ecu in and it work fine, minus cel for no maf present. as soon as they put the apexi power fc ecu in it starts acting up again. they said that the spark plugs were foul up. does anyone with a power fc have any idea what injector duty cycle it should be on, so it doesn't load up to much fuel. thanks..

 

Who tuned your PFC? I'd take it back to them. It could be "loading up" anywhere, most likely, knowing the PFC, at idle. Do you have a wideband? If not, buy one. They're under $400 and a great investment.

 

thanks. do you know if the memory in the pfc can go haywire...

 

Any electronic device can get a short but I've never heard of a PFC "resetting" like the AEM's have been known to do. Do you have a datalogit for the PFC? That's another "must have" for the Power FC.
