Look at the ECU timing. very poor, yet no knock. Why is it so low??? It was 100 degrees out, so i thought it might be the ambient temp causing this. Fuel was impossible to set. I think we were in enrichment all the time. I know its not good to tune in 100-105 temps, but its how we drive here for 3 months. Most people get in trouble tuning in 70 degree then pushing it in 100 plus. I think if you get a safe tune in 100 degree weather, then in 80 degree, you are pretty safe....make sence??? RRR

Hey, attach it as a text file.. DLL isn't digesting it, neither is my other tool..

Sounds like your hitting a coolant enrichment mode.. are the engine temps higher than normal? I think the air is probably lost enough density that your in a different range of load sites than you normally tune in.

Also look at the UTEC's enrichment settings, you can set it by AIT and Coolant temp.. It may be configured to add timing and fuel under these circumstances..

Just a thought... do you think resetting the ECU (by unplugging the battery) will help the factory ECU to rebuild the "base map" for the ECU timing?
