Alright, went to the track last night with the owner to try and get fueling better. Looked like I had it mostly right. Had a few strange issues though.
1. At the beginning of the night, his idle AFR was LEAN (17-19), so I added about 20% to the idling cells for the MAF and got it to about 13's. But everytime after driving around for a bit, his idle would go even richer. The AFR error in those cells were ~-4s. Finally stopped getting richer once it hit 12.8.
2. While reviewing the logs, I noticed that when he would push in the clutch the commanded EQ would go back to 1.0 instead of 1.130 and back up to 1.130 after the shift, so the AFR was thrown off for that time. I had DFCO and CFCO turned off.
I played with the idle base spark table and the car seemed to idle better, but I'm still not really comfortable doing spark. Ordered the Learn@Home book so hopefully I get a better hold of how to tune spark.
Thats all I can think of right now.
Here is the tune and log files.
