Car is stock tune. VE SS.
In my tune the high octane spark table at 600rpm and 0.16 g/cyl is set to 24.
I went for a drive and logged Total Spark Advance (MAF)
and Ive got 3000 counts for that cell, and the average is only 12.4
I have also logged the spark retard, and there was no retard in that cell, so why is the average for that cell not 24?
When tuning for spark, how do you know the car will even run that timing and not something closer to the low spark table?
Do you normally make the low and high table the same? isn't this bad practice as now the car can't pull timing in case of knock?
