    i understand, but my command and error afr's are not working. not sure what I'm doing wrong, but do i need to have them set in the channels list before they will work in the graphs?

    You must log the channel for it to populate in the graphs/gauges/charts.
    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.

    5fdp: right but i guess i don't know what channel I'm missing in order to make it work in my charts?

    You'd still have to set the MAF fail high to 0hz under the engine diag tab and set the 3 MAF dtc's to MIL on first error. Your first tune already had those set, so you are fine there.


    If you are trying to log an "AFR" error you need commanded AFR in the channels. If you are logging an EQ ratio error you'd log EQ ratio commanded for lambda tuning. Replace the EQ commanded with the commanded AFR channel and then you should have you charts working.

    i was able to get them working but i do not have the afr commanded ratio , is it going to cause a problem using it in lambda tuning ?
