Default 4L80e WOT lockup

can't seem to get my 4L80e to lock up at WOT no matter what I put in my tables. The only way to get it to work is by commanding it with the controls in the scanner. Maybe I'm missing something here.

Does it lock at lower speeds? Maybe post your file and I bet somebody can help.

That worked. When are you trying to get it to lock? Right now you have to be in 3rd gear above 94 mph.

Mine is set to lock around 120 mph in 3rd and it does just that. Strange you are having the issue. I can send you my tune when I get home though if you'd like to take a look?

Change the entire TCC min DC table to 90. And scan the torque converter pids at WOT.

heres a scan. the two in the middle of the scan are showing no converter lock and the two at the end show it locking commanding in the scanner. As you can see in the tune lockup is set for 94 mph. Has anyone had any luck with support? Who is good at actually resolving concerns? Every time I send in a concern I get a condescending remark from a certain individual that will remain nameless.
