Hello,
I have a LSA swapped 6.0 with a stand alone E38 harness in a 78 Trans Am. It has the 3 Bar Map (PN:12592525) and the LS7 MAF (PN:15865791). It has FIC 95LB injectors with Aeromotive fuel pump and boost referenced regulator. I have scaled the injecters doing the half IFR/IVT and double Stoich. I halved the MAF and adjusted the main spark airmass table. VATS and Starter Diagnostics are disabled. It has an oil pressure sensor.
I can not get it to run. It will crank, sound like its going to start, and then die. About every other try, it will pop through the exhaust. I have checked coil packs and injectors. I found the driver's side injectors were wired "backwards" and fixed that, but no change. The stock tune on the ECM is from a G8. At this point I took a stock LSA tune and started copying Airflow and spark tables over to try to get it to run and still nothing.
What's even more, I had it running NA before the LSA swap. We had it setup with a fast intake and I had it idle for about 5 minutes before we had some issues with the gauges (thats with the drivers side injectors "backwards" also). As we were fixing the gauge wiring, we put the LSA blower on and now I cant get it to run at all.
I fully intend on taking it to a professional to get tuned. I just need to be able to get it running and have it be able to move under its own power. I have some experience tuning some GTP's awhile back, but nothing like this. I am not sre what to do next.
Sorry for the long winded explanation. Any Help would be appreciated.
