Hello,

I just installed a power Fc on a s4 t2 vert. before the install the car was running an rtek 1.7 with a map ecu piggyback and it ran and drove fine with a bit of hesitation. I installed the PFC with the banzai harness and instructions. with the sample 13bt map the car will fire right up just to die right away, if i change from 2.5ms of fuel in the idle area of the basemap to 6ms of fuel i can get it to idle, but when i try to rev it will cut out at ~2500rpm and die. I dont have much experiance with a pfc but have done lots of standalone installs and tuning, something seems wrong here. what should i check into first?

Thanks,
Matt

 

TPS voltages for idle and fully opened. With a FC single voltage TPS, it goes to both VTA1 and VTA2. Then there is BAC control, and O2 FB.
