If anyone knows how to fix this in the program, please let me know.

The WOT TC Lock Up is hard coded at 95MPH, I ran into this as well, I tried it all and after talking with Ken(LT1edit) he told me it was hard code and he removed it for me, for what it is worth, it did not make a hill of beans in the ET/MPH so no luck there. So it is a PCM hard code.
NOW, with PCM4Less, he might have went into the code and changed it to a number he figured would be good. If that is the case, it can be revised. Ken set mine in the 130+MPH range so i knew i would not hit that no matter what.
Nice numbers by the way!!

congrats on the excellent numbers!!! i am sure you are pretty happy.
i know how much the AFR can limit a motors power, whem mine was tuned earlier this year it it was pig rich and we picked up 30 rwhp just leaning it out for the new cashaft!
now let's see some results from the track!

I would rather not have it hardcoded in the ECM to lock the converter at WOT. It just doesn't make sense when you can lock it in the tables available in Tunercat and LT1 Edit wherever you want.
If I e-mailed Ken do you think he would tell me how to correct this? I assume that I could just open the file with a hex editor and edit whatever address the computer is locking the file in?
Thanks.

Hey Trey,
"Where the heck is the torque curve?
according to my quick math in the good old nogin-
375 * 6500 / ~5300 is somewhere around 450-460 ft lbs
Hopefully i have the forumla (tq = hp *rpm/5280) strait"
It should be HP X 5252/RPM = TQ
That may explain the difference. (I haven't looked at the dyno curves or done the calcs myself.)
Using your example of 375 HP @ 6500 would mean 303 ft./lbs. at 6500 RPM.

You can lock it up lower than the hard coded value, but to get rid of it at 95MPH (stock code) you will have to edit the code.
I would like to know the benefits at the track of locking/unlocking it at different values. I saw no benefit, but others report gains.
