Thanks jc2532. That explanation really did help. It was very clear .

I've heard shiv say that what matters are the numbers a WOT.

I'm not saying you are wrong, you sound like you know what you are talking about. I'm just curious why partial throttle is significant as well. I have lots and lots to learn. And I've always heard it's better to keep it in gear while cruising but never knew why. That makes so much sense now.

Also, how do you think my log was looking . During my run in third gear when I was at 6000 rpm and 90% throttle I was around 11.5 afr. Is this normal or is this running a bit low or rich as I should put it. Or was it rich because I was partial throttle? So many questions!! Haha

Thanks for taking the time to explain this stuff. It is very much appreciated



Edit: i think i found my answer in the sticky tuning reference guide thread

"Typically a ratio above 14.7:1 is considered lean where under 14.7:1 is considered rich. The engine application determines the optimal point. Typically tuners will run a richer mix through higher RPMs (more fuel than the engine can burn) to cool the cycle and help catalytic converter performance. "
