I'll be installing my vafc2 soon for my header install and dyno tune. I've read through the previous safc/vafc threads, but I still am unclear about a couple of things. The first is the low and high throttle settings. Is 39% for low throttle and 90% for high throttle right? And as far as rpm settings, I was going to do 200 rpm increments starting at 2000 and stopping at 6600. If I do that should my lvt to hvt setting be 4200 and htv to lvt setting be 4100? Please correct or confirm.

 

Those throttle settings should work fine.


The Lvt to Hvt setting at 4200rpm and the Hvt to Lvt at 4100 should work, as long as they're not the same.

 

mine is 60% high throttle??

 

Doesn't really matter IMO. As long as when you're tuning for it, you're past the setting and tuning the correct map.
