    Tuning ZL1 FSCM

    Just wondering what everyone is doing to tune the factory fscm for aftermarket pumps. Working on a Fore Triple pump hat with a return style system and wanting to utilize the factory fscm. Deleting the factory fuel press sensor. Thanks!

    The stock FSCM won't handle the AMPs needed for a three pump setup. What's the point of using the FSCM if you are doing away with the fuel pressure sensor? Without the ECM knowing the rail PSI it can't control the pumps with PWM.

    The Fore has it's own controller with a 4ga feed for the three pumps. The FSCM only controls the primary pump. The other two are wired to a Hobbs, to the controller. I wanted to use the FSCM to control prime and as a cleaner install so the pump wouldnt run all the time when the key is on.
