So i have the FC Edit software and i know the scale is 6750 and offset is 250 for the 3 bar MAP. Do i enter that on Setting 3 in the normal row? If so what are the other rows used for? Another thing, in the maps i know P is for boost pressure and N is for timing but what do the numbers represent where the columns and rows meet and what do the color transitions mean? I assume red=bad and green=good? I attached a pic of where i believe i should enter the calibration values below.

 

Let the normal row stay as it is (so you can go back to stock map sensor with just the click of a button for whatever reason). Use one of the other rows, just make sure you select the one you enter the numbers into.

P is for boost, N is for revs. Red and green doesnt have anything to do with good or bad, I suggest you search the forums and find some info on the subject. If you mess up your motor will say goodnight.

 

In the single turbo forum there is a sticky by wargasm. It's a good pfc tuning document. It may help with some questions you may or may not have.

 

I prefer to side on the safety side as the stock values are so easy to get if you need them again.
Change all 5 to match your currently installed map sensor. Then you never can get fracked over by accident.

Most importantly, those values are not calibrated and cause PFC errors. I have actually calibrated 2 GM 3 bars, 3 Apexi 3 bars, and 5 stock 2 bars. This resulted with calibrated boost values actually matching PFC recorded boost values, and source values.
