    Do you have logs that contain spark, airflow and cylinder air mass? your trans torque is really jagged and that looks to be causing issues with your shifts, on the one-two change at about 3.56 you...

    Figured it out, I had to add the MAP values manually in the virtual VE to see those calculations, mine was only showing to 105kpa until I added the ones above that.
    It seems weird that the VE...

    Maybe I'm missing something as I'm not familiar with LSA engines but the tune you posted only has the virtual VE table going to 105kpa?, if you're not using the MAF how is fuel controlled above...

    Is that the @50 or advertised duration? maybe post a photo of the cam card. I'm far from being an expert but a cam with more intake than exhaust duration is unusual for a N/A LS motor. Was it spec'd...

    Your TCC slip RPM looks to me like your TCC is not locking. Maybe that's why your line pressure is 0. You need to figure out why its not locking. Have you logged TCC desired slip to see what its...

    Do you have a log with TCC desired slip and TCC line pressure, that would make it easier to see what's going on.

    While you will show more power on a dyno with a locked converter I think your...

    Sorry, I thought you were refering to the torque converter slipping rather than the torque converter clutch, my mistake.

    A high stall converter will slip more, not less than a stock converter, thats how they're designed.

    And personally I'd be more concerned about the knock in that log file rather than the converter...

    It looks like a hole in your VE map, MAP pressure doesn't change but your VE airflow falls overs and fuel is correspondingly pulled. What does it do if you run in MAF mode?

    How much of a gain do you get by running at 16:1 over 14.7? Is it worth the effort? I would have thought lean cruise was dumped by GM for a reason.
