After playing around some more, it seems I'm still getting a few degrees KR at times while cruising in 6th. Funny enough, even the stock tune was getting KR around the same area.
I took your advice and set the TCC to unlock at 44% TPS for 5th and 37% for 6th, as well as raising the TCC release speeds for lower TPS%. My question is, does the TCM use the Accelerator Pedal Position, Throttle Position, Relative Throttle Position, or Commanded Throttle Actuator to determine TPS?
In my latest log I'm still getting KR due to the TCC not releasing in 6th, although all the release conditions are met. As an example, with the tune setting a release speed of 68 at 31% TPS, the TCC still refuses to unlock at 62mph and 34% TPS, which is where I'm getting knock.
I'm terrible at explaining things so I've gone ahead and attached the latest log.
Also, I'll be going back to leaving the TCC unlocked in 4th. I've been messing around with BlueCat and I don't think it plays well with trucks. The original BlueCat settings were lazier than factory, and setting the min lock up gear to 5th made it shift to 5th at 25mph. I had to set the factor to 1, max out the upshift and downshift parameters, and lower the offset as much as possible without running into a logic error just to get a baseline tune. Even after using the max values, I still had spots that were lazier than factory. Could be user error though!
