Trying to tune using Moates Autoprom and TunerPro RT. There is a disconnect between what the programed timing is and the actual. As soon as the TPS comes off 0% the timing (SA-REF and SA_TDC) jumps to max 40+ degrees advanced (reported and actual). Base timing is properly set at 6 degrees. All SA adders have been zeroed out and the Spark tables call for only 20 to 27 degrees in the 400 to 1400RPM and KPA 20 to 60 range. I have tried various combinations of 2 ECMs, 2 DUI distributors and 4 different distributor control units. All with same results. The car is a 1991 Corvette L98 383 used for road course racing only. Anyone dealt with this problem or can you see some problem with my bin? I have spent many hours on this and other forums haven't found any insight to this problem. Any help would be welcomed.
Bin, ADX and XDF files attached.
