Need some help with knock
Need some help with knock Haven't had time to get back to the dyno, but log the car a few time and
a/f (12.7-12.9)lookd good through frist and second gears. when it shifts to third my a/f goes up to 13.0-13.1 and i get knock 3-4 degs
the knock comes in a at 5233 rpm and tapers down to 5824rpm
I'm running 25-26 timming at WOT
