Hi, Im about to install amidpipe with the base PFC map and have

Intake DP MP CB and efini y-pipe.

I know its probably best if I were to richen up the mid to upper RPMS.

If I go into the PIM voltage, theres normal, setting one 2 3 4 etc. so I do next on normal, which gives me the volatages from 1-8k rpms. all at 1.00 . Is this what I want to change? I should add probably around 5 percent fuel correct? Does that mean I want to change it to 1.05?

Thanks

Steve

 

I have the same question. What exactly do you change? Add 5% for each rpm listed? Add 5% for each PIM voltage listed? I want to make sure I do this right.

 

figure out what your PIM voltage is at certain boost levels, and adjust the fuel that way....if you take out fuel in the rpm screen, it will take it out under any boost condition, so ideally on a dyno you want to tune w/ the voltage screen

the different "options" are for different map sensors which have different voltage ranges, don't mess with those....

 

so wont just increasing fuel at like 4 or 5 k plus just be suitable?

and if I take some out at 1k rpms after removing the air pump that will lean it out a bit wont it?

 

you're on the right track

 

okay. How much do you reccomend be removed when the air pump is no longer present?

 

i have no experience with that....however, i will say, most people turn off o2feedback when they remove the airpump, maybe that will help

 

Hmmm. I imagine that would work. thanks.
