  1. I didn't open the injector data on this computer...

    I didn't open the injector data on this computer but are you running a much higher fuel pressure than 3 bar?

    Rough math puts those at just over 83lb/hr if running 4 bar pressure.

    Otherwise the...

    Yes, the virtual flex fuel is garbage and I've seen it happen many times where it gets stuck at 30% or even higher for no reason even when the customer has run regular pump gas for thousands and...

    This is where it gets frustrating, people should stop copying tunes from other people when they have no idea if it even matches stuff done to their vehicle.

    It's even more lean than the previous log and you lowered your idle speed more than I think you should have. I said try aiming for 800-900rpm

    Is your fuel pressure okay?

    Is the exhaust...

    Return the base running airflow back to stock and start over. To me you have added way too much there. Add like 20-30% and see what that does.

    The fueling is still lean as well. Add like 3-5% to...

    If the OS is blank, it was changed.

    You can see that in the calibration details page, it says you applied the speed density enhanced OS to this file.

    Change the system options back to it have a drive by wire system, see if that does anything.

    If that does nothing, then flash the computer back to the stock 5.3 tune file. Then copy over stuff...

    Well that is partly where you went wrong. The file you posted says that the computer doesn't have drive by wire anymore. The system options needs to have "1" in the ETC column for the GMT-800...

    Looks like it has flex fuel injectors too?

    The over/underspeed spark correction have the same value, that isn't right. One will be positive and the other negative. Look back at your stock file to...

    So you converted the 2005 computer to run with a cable throttle body instead of the drive by wire?

    Did that computer support the cable swap with the TPS and IAC drivers on the circuit board?

    I honestly did nothing when we put a Th350 behind a 5.3 in rock crawler.

    Left the transmission as a 4L60e, disabled all abuse modes and transmission related DTC's. As well as anything else that...

    You can just hook it and make changes straight away so long as he didn't lock the computer, which many people rarely do anymore.

    Your fuel injector data is wrong. You said it has 440cc injectors, that roughly 41-42lb/hr but your tune file shows stock 30lb/hr injectors.

    That's probably why your VE table looks so weird...

    Seeing the serial number in the VCM suite info page is right, it's not suppose to show the VIN number there. None of my licensed computers show the VIN number there.

    These computers don't use a wideband, so it was never "connected" to the computer anyway. You were just logging it with the MPVI2, so it can be left on all the time.

    Smoke was a GM engineer and for others as well, I'd think what he is saying is pretty well true. We are just good enough at being hacks to make stuff work on these later model vehicles.

    People sure like to go from 0 to 100 with camshaft swaps these days. Super mild stock camshaft to some pretty spicy camshaft.

    You didn't put the MAF dtc's to MIL on first error. That should help it revert to speed density straight away.

    Fueling is going very lean when under load. Either you have a fuel pressure problem or that MAF curve needs a lot of fuel added to it. I compared that MAF curve to a stock one and you are way way...
