Strange it's working fine for me? Can you refresh and try again?
I logged again and the peak knock retard is now 1 degree...It definitely likes it fatter with the lower fan settings.
Any other differences between the 91 and 93 octane besides a couple degrees timing?
I think I'll bump up the timing in the 91 tune and go a little fatter again to see if I gain much...Maybe 2 degrees more timing and 2-3% more fuel...)
I'll let you know how it goes
Cheers,
Chris
