Re: anyone have a d15 non vtec bin fro crome???
 

The point is to eliminate hesitation on high A/F by playing with ign. timing. We all know that it can bee fixed by ading fuel.
The burn of the flame fromt in the cilinder on 17, 18 A/F is 2x slower that on 12,13 A/F. So I decided to advance the timing on low fuel cam and ti works.
The car does not hestate it is just lazy because there is less fuel.
