    There are minor differences between operating systems and vehicles. They changed stuff between 2012 and 2013 as well as between half ton truck and full size SUV.

    The bulk of the data is the same...

    I feel you will be severely limited with the stock computer on those injectors and that much horsepower.

    There is no easy way to properly scale the tune for such huge injectors and that much power...

    Do not disable torque mngt if you want this transmission to live. The 6L80e must have TM enabled otherwise you will be rebuilding that thing sooner rather than later. Whatever video's you saw that...

    Which version of the software do you have?

    I think I am running the most recent download on the website.

    What injectors are installed?

    They must be really big because even with the scaled method being used (which is still has an incorrect setting), the flow rate for the injectors is maxed out. So...

    I'm not familiar with those injectors. You'll need to see if you can get the data for them. You will need the flow rate at 58psi, min injector pulse, short pulse adder and offset vs volts data. Then...

    If possible you could exchange that wideband for the AEM OBD2 wideband that involves zero extra wiring. They cost a few more bucks but they are way better for ease of tuning.

    The wideband you have...

    Try reducing the min fuel milligrams in the transient tab by half.

    Speed density should have codes P0101-103 set to MIL on first error too.

    What brand injectors?

    What 2 bar MAP sensor?

    Post the tune file.



    All 3 log files say it's still running stock 33lb/hr injectors and not 60's.

    I'm not sure what you mean, the offset data that I made is different than your tune file. You should be able to copy that over just fine.

    Flat line the injector flow rate for that style fuel system. I was just copying stock data to stock data as I didn't know what you had.

    Should be okay setting it at around 54lb/hr then.

    I did it for you, take this file and copy over the injector data. I did it the best I can and I had to do a lot of it by hand to make it work with that spreadsheet, it just takes time to use it.

    I'd say your thermostat is partly sticking open if it can't get the coolant temp any higher in that type of weather.

    I had mine stick open on my 2016 5.3 engine and it would struggle to get over...

    Engine size, cylinder volume, base running airflow, MAF/VE table and power enrichment settings should be plenty to get it going. The little stuff different between the two won't make a huge...

    Reset the LTFT with the scanner before data logging, that is how they will return to zero.

    The coolant temps looks fine to me in that log. It's staying around 190-205 which is perfect if you ask...

    Something is way off with the base running airflow too, there is no way it should be that high. I'm surprised it doesn't want to push with that much airflow and that high of an idle speed.

    You didn't change the speed limiter source from GMLAN to calibration. It won't matter what you set the speed limiter to if you don't change that table as well.
