Ok, i've been datalogging the knock. But how do i know when to retard or advance? Is there a certain volt that it should be at? For example, a/f is good between 11-12 in high boost..what about knock then? THanks, sam.

btw, did some tuning at 15psi on the highway last nite...a/f was between 11.5-12.00 whole time. FJO is awesome

 

bump..
