If you have a daul stage boost controller on your setup, to allow you to switch from say 7 psi to 12 psi or something to that effect, how would that switch effect your fuel maps and such?

I mean, when you tune your maps, arent they only good for that particular boost level? Could someone explain how this works?

 

if you get tuned to 12, everything under 12 is tuned also.

 

Ah, so say you are tuning with Uber, and have your boost set at 10 psi. You burn a map for 10, but then immediatly afterwards you crank the boost back down to 6 or 7, would that cause you to run richer in the lower boost application?

IE if your cruising and hit 3-4 lbs, your tuned for that, and if you go WOT and hit 10, your tuned to that too

Since the map sensor only see's 6 psi, it only gives it enough fuel to cover that.

 

yup these guys are right on. if you tune for 10 psi you are all set for 10 an below, you will not have the corect afr and timing fom all boost levels 0-10psi. this is because our maps read MAP vs. RPM. so if you are boosting 10 psi is reads from that column but if you are only boosting 7 psi is will read from a lower column and give less fuel.
