This is probably a dumb question, but I haven't been able to find and answer on in the forum.
When I look at the TP/RPM grid on a PC map, does the value in a given cell relate to the percentage of fuel delivery increase or decrease vs. the stock map in the ECU at the same TP/RPM setting? For example, if the value in a cell is -9, is that telling me that the PC map I'm looking at will deliver 9% less fuel at that TP/RPM combo than the ECU would deliver without the PC installed?
My reason for asking is that I just purchased a PCIII USB off the board and am trying to get a bit smarter about how to read the software output while I wait for the unit to arrive.
Thanks!
