xr4tic, about your psc001,
 

i have mine set as signal calibrator, and voltage.

i have it hooked up to RPM and spliced MAF signal going to ECU.

just wondering, could you read the MAF signals? because i can't. (i presume its the voltage on the fuel map = MAF signal).

i wasn't sure if i had it set wrong, but just wanted to know if you could read the MAF voltage signals or not.

which one do you have?
 

I have the PSC1-003, and I have no problem getting a voltage signal. If you have the same one, then verify you have the correct signal wire hooked up.

psc001-001
 

i was told that i could just leave out the psc001 internal MAP disconnected, but it seems that was just a BS, and that MAP only supports upto 16psi only despite 2.5bar map

Yeah, the voltage signals on the fuel map are for the MAP sensor on the PSC-001
 

The 001 is mainly for speed-density cars being converted from NA to turbo.

MAF equipped cars should use the 003.
