Timing in tune doesn't match log...

[LS1FREEK]

I've been struggling with this for quite some time now... I know i'm just missing something simple but SOMEONE PLEASE HELP ME!! lol Ok, check the timing set in the tune and then watch the log... I got 23 deg in the tune but its logging 25-27??????

To accurately log timing, you need to select GM DYNCYLAIR.DMA or GM.CYLAIR.DMA as one of your PID's.

If you do that you will see your timing is not 23 degrees as you think (the DYNCYLAIR is not that high). In fact with your KR of 1.5 degrees you are actually commanding 27 degrees.

Add those PID's and then link Table B5913 to the Scan Tool.

The bottom line is you are not in the '23 degree' area of your tune..
