I am looking for some help for advice. 2014 GT500 with mods. Working on the tune. Doing a pull in 4th is good until you get close to 5k and then stops pulling and seems to be like breaking up. Doesn't seem to do it in 3rd. I was in 3rd doing a pull to close to 6k and didn't do it. Just seem to do it in 4th. I have attached the log if that helps.
You are hitting limits like "trans trunk" and your TB angle error is -15* is what jumps out at me. I like to monitor spark source, fuel source, driver demand limit source, throttle angle source, and torque air limit source. Usually breaking up is a limit using fuel and/or spark to control power in my experience. hope this helps.Originally Posted by mlecy
ok. Would that also cause just one bank to go lean? If you noticed in the log when that was happening bank 2 was going to like 20 A/F.
