I d/l'ed the newest version of the software and Flashscan drivers. Next, I loaded a stock Z06 high octane, low octane and base spark tables into my friends '99. The minor changes to the idle and light throttle areas were adjusted for in the new table so his cam would idle without surging. Like before, these changes took. Then, we went out and I logged the base DMA and run DMA spark PIDs. According to the "more info" feature, the base DMA is what comes from the high/low octane tables or base spark tables.....and the run DMA is the commanded spark once all of the modifiers have been added/subtracted. At WOT, a stock Z06 table commands 21.99* spark advance. While we were logging WOT, I saw .5*~1.5* more timing than the 21.99* I entered in the table. Also, the base DMA matched the run DMA, which further proves there were no spark modifiers affecting the timing at WOT. Why won't this car run the timing I'm telling it to? The only positive modifier I did see was in the XMSN(?) DMA I think. My understanding is this table comes from a torque management related table. Any idea where to look for this? I used the search function and found nothing. Why would torque management ADD timing? His trans abuse is disabled...he just has the factory torque management settings for the upshifts and my issue with the timing is way before the trans even needs to shift.
This is beyond frustrating!!! ME >> << Timing gremlin
