One thing I've found is you need to have all the tables matched. So high octane, low octane, spark in gear, spark in park, and optimal timing all have to be equal to have the exact timing you want when using the cos timing functions. So just take a little time and closely match the cell values and you should get the result you want.

Got everything copied and matched. Will try it out tomorrow. Thanks!

Oh and lower B6619 and B6620 by 1-5 to get them back in range. Whats with the throttle position only showing 87.5-88%?

Any time to test it out?

Yea I tried it last night. Had it commanded to run 7.5 degrees and it ran 5 degrees. Ill post the tune and log tonight when I get home.. In kinda wondering if it has something to do with the TPS not reading right..
