I am working on a 2008 LMG 5.3 using an E38 ECM. We are tuning the engine on a dyno for ultra lean burn operation. I would like to program a simple fuel strategy using just the pedal position and adjust the injector PW without any other input influence or electronic throttle control. A direct pedal/fuel table. No MAF, ECT, O2, MAP, TPS or ignition input. Sounds old time, but for testing I need it simple and I'd like to use the OE ECM.
