My friend did a street tune on my vafc and for som reason i think the car is running too rich because i can see them on the plugs...my question is how do i lean them out? also...the way how the vtec is set up is from L->H is 5600 and H->L is 5400....does it matter if i increase the H->L by another 200..so that will make it L->H will be 5600 and H->L will be 5600...so whats effect on this on the car? thanks much...kinda long but pls help...

 

well i know on my SAFC, u need to go to the settings menu. then there are two options that u can choose, high throttle or low throttle. choosing one of them will allow u to lean or richen the fuel micture. low throttle is for the settings during low throttle driving and high throttle is for high throttle driving. i think the VAFC also lets u tune it based on when VTEC kicks in and when VTEC is off. not too sure though about that

 

Lvt is for Low throttle, and Hvt is for high throttle....correct me if im wrong...also does it matter to go only 200 on between L->H and H->L im talking about the difference when vtec is being set..thanks
