    No, no progress on this front, and eventually I just stopped messing with that part of the tune, disabled shift lock, and set up the lock tables to essentially only lock while accelerating to remove...

    If it's what I think it is, check your "Safety Shift" tables, and make sure they are set the same as your pattern a/b tables.. I fought an issue that sounds exactly like yours for the longest time...
  3. 6L80 Keeping Converter Locked For Closed Throttle Shifts

    Hi all,

    A little background. My car is a 2013 Corvette with H/C/I/E/Meth. I'm running a Pro Torque 3200 3-disk carbon converter that holds lock no matter what - low throttle, WOT, during upshifts,...

    Mods, y'all can archive this, or leave it as an instructional for future people with the same issue.

    Not sure what the factory intended purpose is, but the "Safety Shift"...

    Hello,

    I have a 2013 Corvette LS3 with a 6L80 and I have a weird shift point issue that I can't figure out.

    In D-Mode, everything works exactly as expected based on the tune. TUTD works just...

    Weird spark advance on deceleration

    Hello all,

    I'm currently tuning DFCO entry (and a few other things) after new exhaust, headers, and a ported intake manifold. I have my WOT and part throttle tune pretty much dialed in; I'm now...

    Custom Serial Parameters

    Greetings all,

    I first posted this in the VCM Scanner section, but I think it may fit better here:

    Is it possible to set up a custom parameter to obtain data from a serial data...

    Custom Serial Parameters

    Hello,

    Is it possible to set up a custom parameter to obtain data from a serial data stream? I have a TechEdge 2COB wideband O2 sensor setup, which outputs lambda data over a serial cable. The...

    Good to know.. I don't suppose there's anything on the horizon allowing us to reprogram either the ABS controller or the instrument cluster itself to apply a correction factor? I know hypertech sells...

    Firstly, as mentioned here, reset your shift adapts. That will get rid of your slip, at least temporarily.

    Second, to permanently solve the issue, you need to adjust the torque model in the...

    Just some helpful info from my experiences:

    If you have a factory converter (at least this was the case on my 2013 C6), it is designed to "slip" a few RPM without any ill effects. I believe it is...

    Is your CAN network terminated correctly? The E38 and T43 controllers talk via the GMLAN CANBUS network, and if you are missing a terminating resistor or any connection between the two modules, you...

    I have a 2013 Corvette with essentially the same transmission (6l80 vs 6l90 shouldn't matter much) and shifting with tutd is pretty instantaneous... However, the switches in the Corvette are wired...

    This is true to an extent. Just depends how much engine tuning you're willing to do. I'm running 232/241, 620/612, 114+3 (which I consider to be fairly aggressive) with a 650 RPM idle and I can drive...

    Well in that case I can almost guarantee you're not overpowering the clutch assembly, as my triple locks at 5500 RPM at WOT in 3rd gear without complaining a bit. Hoping changing the tune up gets you...

    You'll find my tune attached below. Sorry I didn't post it earlier as I didn't have access to my PC. Most of my tune (with the exception of the TCC section) comes from adapting the parameters in the...

    I have a 2013 Corvette with heads/cam/etc and a Pro Torque 3200-stall triple disk converter. I lock mine in 4th gear when driving normally, and I lock in 3rd when using the paddles.

    I personally prefer my converter to stay locked as much as possible unless I'm on the strip, so I have my tables set up to downshift rather than just unlocking the converter. This is a better option...
