Trying to track down a knock retard (tip-in) problem. I thought it might be burst knock, but logging BK it's alway 0. To double check this, I'm looking at logged dynamic air vs the values in the "Burst Knock Enable Cyl Air Threshold vs. RPM" table. To do that I need to get dynamic air per cylinder (is that right?). Someone posted that you do this by looking at the frame-to-frame difference in dynamic air and dividing by 8, but that can't be right because those values are much larger than the table values, it would awlays be in burst knock mode. So how do I calculate the correct dynamic air per cylinder, to compare to that table in the tune file?
