I just logged some data during 20 minute drive and was wondering if someone could help me decifer this data how to improve the numbers? Hp tuners will be used. Three different sections of data are shown below.

Sorry bout numbers I guess I should have previewed it

 

You're running lean based on those ltrms. Richening up the mixture should help with the KR too. Multiply all the data in the IFR table when you get HP tuners by 96% and see if that helps. If your LTrims stay positive, multiply by 94%. Decrease the table, and the system will add more fuel. The goal is to get them in the -2 to -8 range consistantly.


At least that's what I've been gathering by reading the awesome threads here on ls1tech.

 

Thanks, I'll try that!
