Has anyone got a print out they can post of their AFR readings at different rev ranges for a modified RV8 450 or 500
Thanks in advance

I'm not sure if I'm reading that correctly but that looks like about 14.2 right at the top of your power band... Isn't that a bit lean? I've always been under the impression that you want around 12.5ish when fully on the beans?

A few different chips 5bhp between them...



With a knackered afm



Nothing showing idle AFR
