i talked to apexi and could not get a straight answer on what the p values in the inj map correspond to. the vertical axis is rpm but the horizontal axis is what? im trying find out what column i.e. 7? 12? corresponds to atmospheric or 0.00 bar on the boost guage. im trying to richen certain parts of the pressure range above 0.0 and leave those below that value alone for good response and fuel economy right now im guessing that p-9 is around 0.0

 

If you read the PFC manual, it tells what it is.

And I have discussed it and how to calibrate the map sensor a few times.

If Apexis's tech people do not know what it is, well that is pure %&^&&^!

This info has been covered before. cewrx7r1 has spent countless hours posting info about the PFC. Please use the search function, but I'll go ahead and post this just because I was working on it yesterday and have the info handy.

 

each 10000 is essentially 1 kg/cm^2 of MAP, with the value 10000 being atmospheric pressure, 20000 being 1 kg/cm^2 of boost (boost value 1.00 on the commander display). 1 kg/cm^2 boost is equivalent to 14.22 psi boost.

 

^+1, and the max the stock MAP sensor will/should read is 21500, or 1.15 kg/cm^2.
