I've gotten the driveability aspect of my Regal pretty close and I'm slowly working my way into tuning for power. I am tuning via the narrowband. I scaled the entire upper portion of the MAF up because the car was dangerously lean (770 O2s) in the upper RPM range.
I figured it was safer to start tuning some heavy throttle apps then jumping right into a WOT second gear pull.
There's one point in this scan where I get about 5 psi, but it is only commanding 9.5 degrees of timing while the corresponding cells in the table show 13-15 degrees of timing. (Starting around frame 4000)
It is not hitting any cells in the IAT or ECT spark modifier tables.
Car is a 99 Regal LS, top swap
Is there a table im missing or something? Can somebody clue me in? Is this some kind of torque management?
