The LS9 and LSA operating systems seem to properly correct injector flowrate when they enter boost, but it seems all other E67 OS's, as well as I believe all E38 OS's stop correcting injector flowrate once they go above atmospheric pressure, and thus a fueling error gets built into the VVE and MAF tables...which can in a turbo car result in some funky fueling.
My solution to this point has been to run a return style fuel system with a 1:1 regulator and set the injector flowrate to the same value across the board, but if it's possible, on low boost setups where expected power is comparable to the LS9 and LSA engines, I'd like to somehow tell the ECM to properly follow the injector flow rate tables into boost.
Does anyone know the solution?
