So, I can use any spare output (ING, INJ, P259, stepper, Drive-A/B) for misc outputs like IAC (PWM), boost (PWM), shiftlight, tacho, fuel pump reley, tank vent valve, coolant vent, etc... All I have to worry about is supply current... Right?
What about misc inputs? I need inputs for: LPG (switching configs), ALS, Flat shifting? Also I need monitoring (analog) for pressure in LPG rail. And anything else I can't think of now?
