I don't know about you guys but I thought a dyno sheet database might be of some value here. If you have sheets feel free to send them to me and I'll post them up.

Guys, guys. That is not the correct AFR. That is what the dyno calculates it at using an equation. It is not actual. I have Widebands that log in the dyno in a different page. They actually are running 11 to 11.5:1. The EGT's stay nice and cool and the BSFC collaborate what the Widebands say.

The equation it uses for the AFR column is antiquated and incorrect.
