I take it this is for the Fiero. You just hook it up to one of the injector bank ground wires, does not matter which bank, each goes to a separate injector driver in the ECM. There is a main injector ground off the ECM, but it will not work. Considering that each bank goes to 3 cylinders, the other bank has to inject basically the same amount of fuel to complete the engine cycle. Ive hooked up the mpguino to 3 different GM V6s of this era, one of them a 2.8 MPFI. 0251500000 should be a good starting number for your microseconds/gallon. When I say high on fuel use in my fuel log, it is my own notes for how much above the theoretical 0240000000 based on injector specs only. Your results might be a bit different, considering the iron head MPFI 2.8 used a cold start injector. Im not sure exactly how much fuel it injects or for how long.
