    2021 Global B GM vehicle (Yukon w 6.2) - many missing variables (knock, misfire etc)

    Anyone else have issue with missing variables for 2021+ GM Global B trucks and SUVs?

    For example - on a 2021 GMC Yukon XL some of the key logging variables missing appear to be:
    no knock retard related variables (real knock or burst knock)
    only have the main spark advance - none of the specific modifiers (IAT, coolant, PE, etc)
    no misfire monitoring related variables (total count, per cylinder current/history etc)
    no dynamic airflow/calculated airflow variables
    no cam phaser related variables
    no AFM/DFM related variables/status flags etc?
    no injection pulse width
    no SOI/EOI valuss
    no split pulse related data
    no fuel flow rated variables (instantaneous fuel used, fuel flow...)
    no AFR (has EQ ratio/lambda but not AFR)


    I have updated to the latest beta version - no changes. I repolled for supported parameters - no change.

    I am on version 5.1.3037 Beta right now.

    yes, I'am tuningGlobal B GM vehicle, many missing variables,

    you need to open a support ticket. Let the official engineer add the variables you want for you

    Maybe this is the best way

    Go into the edit tab up top i think it's the edit tab. Pick the advanced option, they will show up.

    This is a question about the scanner, not editor. There is no basic/advanced mode for the scanner.

    I think you actually have to unlock the ECU to see some parameters. At least you used to have to. Not sure if this changed as I don't see many Global B vehicles yet.
