hey - quick question. I don't know if I've watched the matrix too much but my car is showing timing patterns that almost look designed by hand.
e.g. 5 out of 6 cylinders at a partial (but not neutral) throttle load are the same but cylinder 2 is a retarded by a couple of degrees until higher revs or more load applied.
At other times, under a trailing throttle cylinders 1,3 and 5 share one timing, 2,4 and 6 share another timing value, out by a couple of degrees. Or as the throttle is lifted cylinders 1 and 2 go out of time to the rest.
Is this timing, or 'sound effects' engineered by BMW / COBB? It almost looks designed by hand - very linear.
no codes were thrown when I look at the AP.
Thanks in advance.
Chris
