my afr starts at 14.6.... when i go WOT it drops down to 11.7-12.0 for .1 to .2 seconds then comes up to 13.0-13.3 for 2 seconds then afr goes down to 12.5 for 4-5 seconds and goes 12.5-11.5 for 5 or so seconds.

is a 13.0-13.5 considered a lean spike early on when spraying or is it more 14.0+ that's considered a lean spike?

 

I would think that anything higher than 11.8:1 to be lean

14.6, 12.0, 13.0-13.3, and 12.5 are all lean to me
