    Flex Fuel flex spark table adjustments

    I have a P59 flex enabled. I see the additional timing being added, but appears to add the entire amount. I am wondering how to get the spark to adjust based on the amount of alcohol the sensor detects. Anyone have any idea on how to adjust?

    That computer won't do it that way.
    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.

    The spark blend table is filled in-- what is the current E content? You need user defined parameters to adjust it, it's not included in the HPT definition file.
