B I N G O You nailed it. I was using an emulator and did not disable check-sum. It kept showing timing offset beyond 50 degrees and did go to the limp home mode. The car (32 Ford) was a 1991 Camaro transplant and no check engine light was wired. I sure learned a lesson on this one. Problem was ident...

I picked up a chip, download stock tune to emulator, made some changes everything worked fine (so I thought)...

What bugs me is when I use TunerPro RT the baseline distributor setting pops up at 50 degrees. I re-set it to 10 degrees but on the "dashboard" of the RT tuning program is shows up as 50 degrees. I suspect that the baseline timing (50 degrees) virtually exceeds the max timing of 50 degrees...

I bugged the wire from the ECU to the distributor and it's plugged in and connected. When I disconnected it to "set the timing" and re-connected after static timing was set. The leading edge of the spark is exactly aligned with the reluctor signal from the distributor. I have a spare ECU a...

I'm working on a 1991 Camaro transplant in a '32 Ford. The Spark Advance Initial shows 50 degrees timing in the data logging dashboard. The Spark Advance Initial (distributor initial) is set to 10 degrees advance in the parameter table and the distributor is physical set to 10 degrees. Problem is ti...
