I have a 98 honda civic ex and put a LS Swap into it and had a turbo kit put on. I also have a FMU *Cartech* and an APEXI S-AFC. Here is my problem. I can turn the car on and it will idle fine. However, when I apply gas, anything over 2000 rpm it runs VERY rich. I have tried everything with the fmu to turn the fuel down but nothing works. I mean it is soooo rich that the smell of gas from the exhuast hurts your eyes. Is there anyway in the APEXI unit to turn the fuel down at higher rpms... I know there is a high/low trottle setting but im not sure how thats works... Any help is greatly appreciated. Thankyou in advance.

 

oh wow.... you really need to get some help with your SAFC. Why are you running it with an FMU? My first suggestion is that you get rid of the FMU and go buy some remanufatured DSM 450s.
