    Just quick question about PE value

    I'm new, just trying to gain info. Question about PE value. If I want to run 12.5 afr/.85 lamda, why do you input 1.15 into the PE table? Just curious.

    Just looking at it from lambda, you want to add 15 percent fuel or run 15% richer to get from 1 to .85 so you multiply the values by 1.15 to increase each cell by 15%.

    Also the 12.5 AFR target value is assuming you are using 14.4ish stoich value too. The number would be greater if you had 14.68 as stoich.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
