Thread: Apexi Safc and safc 2

Was wondering whats the difference in the Apexi super AFC and Super AFC 2, they look different but are they actually different? Also can i run 4 bar using a SAFC on my fuel rail with a stock ECU and an aftermarket Fuel pressure regualtor set at 4 bar?

why?

safc2 has more adjustment points than the safc and a few other options as well. You could use a safc to adjust for larger injectors and a different maf but how big you can go depends on what the stock ecu is programmed for. You can go up to 50% larger on the injectors. I like the safc2 for fine tuning but not as a primary tuning source because when you screw with the maf signal you are messing with the timing as well.

if you want to go 4 bar you need to re-program the ecu.

K I have an ecu programmed for 700cc injectors and Z32 maf, could I run that and take out my stock?
