OK, i have a 402 gen5 LT, it will be be running with port injection only with VVT, T56, custom swap harness for my Blazer ZR2, E67 ecm. I was thinking the GMPP LS3 crate engine E67 calibration was a good starting point, as mine will be NA, but that calibration doesn't have VVT, so can you just enable it, or have to do a segment swap.
I will be using a stock LS3 TB on a Holley high ram intake, with Holley 100pph injectors, stock LS3 coils.
The other thing im trying to do is run a fuelab brushless 500lph in-tank pump, and their brushless controller is PWM, 0-5V or full speed, i was thinking the 0-5V and splitting the TPS signal to feed the ecm and the pump controller, not sure if anyone has done this, my google searching hasn't found much.
