I have a 2010 VE commodore LS3 that doesn't have a FPCM from the factory and I am going to upgrade the fuel pump with a ZL1 unit.
I see in my tune under the fuel system tab that there is an "FPCM Fitted" YES/NO box.
Does this mean I can install a genuine FPCM off a series 2 VE and turn it on in my tune and get it to work?
Is there any downside to running an FPCM over just running the ZL1 pump with the upgraded reg to controller pressure?
