I think that's my biggest problem. I rebuilt my KR histogram by hand, but when recording only the RPM axis updates. The Airflow g/s won't change. I think it may have to do with not having the right sensor (SAE corrected, specific, or generic) sensor logging in the channels view. I need to play with it when I have more time. I upgraded on my laptop, then went to log to troubleshoot an issue and found out right then in there in the driveway things were not the same.![]()
