Question "LEAD TIME" needed for TCC LOCKUP to happen?
Do you, or should you, also need to have (or should I say, ADD) lead time on TCC lockup?

Is it commanding lockup and it isn’t happening? Or is it just not commanding it. Are you logging TCC mode? Sorry on my phone and can’t see the scan.

Does the ECM have a hard limit that keeps TCC from locked at WOT?

I'm hoping it may just be operator error...For some reason, I had the UNLOCK MPH maxed out, so on another board it was suggested it will never lock with the unlock MPH higher than the LOCK MPH...which makes perfect sense. I won't be able to test it, until next Test & Tune day. 127mph lockup tests are just a bit too much for neighborhood testing, lol.

I don't believe so, guys lock up their converters with more power than me, and assuming, more mph than me as well.
As said above, I think it was simply an error on my part. I was intent on locking converter, I never even thought about the unlock mph's effect.
