I thought about posting this in the data logging section, but I think it's a carb issue. Hopefully you can view the files. The E5 run was a 1.357 60' and the E4 was 1.409. I know it spun on the E5, but I have other runs where it spun the same and the 60 wasn't so bad. The E5 afr goes much richer than the green and it corresponds to a dip in rpm. These runs were 22 minutes apart and the E5 run had about 250 feet better AD. I made 8 runs on Sunday and this was the only time it did this. The E6 run was back to a 1.352 60'. The carb is an OS 9375 on gas with 94 main jets. The carb has a major restrictor plate in it and the throttle is backed off to help slow the car.
