    2004 Z06 Histogram

    Trying to help a friend out on his new build, He got a email tune and its running very lean.

    Wanted to just log his tune see what's going on before adjusting anything. Im confused not sure what im doing wrong, im not getting any data in my histogram for MAF HZ. Hes going to order a wideband to make sure everything matches but wanted to get my Histrograms and Pids ready before tuning.

    Graphs/charts don't read if the channel isn't being logged.

    Add the MAF hz channel in the logs and the graph will populate with data.


    Compare the MAF/VE tables with a stock tune. If for whatever reason the MAF/VE have lower values in the tune that could explain the lean issues the fuel trims are showing. The VE table to me doesn't look right.

    Also make sure there are zero intake leaks with the aftermarket intake.
    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.

    Thought I had it logging. I'll add that pid, the ve doesn't look right to me also. Comparing to stock i found in repository. The VE tables are quite a bit less.
