Default TCC Lockup @ WOT??

Anyone (through LS1 Edit) lockup the converter in 3rd for 1/4 runs?

Good, bad? Issues?

Also, I'm looking to monitor TCC lockup in AutoTap and the only parameter I can find is TCC Mode" and it reads 0,1,2,3 or 4. ?? It looks like 0 is unlocked and 4 is locked but what the heck are the "other" modes? Isn't there a simple TCC Enable line to watch??

It is hard on the converter and only helps significantly if you have an inefficent converter. Don't lock-up too early or you'll kill your powerband.

-------------------------
1 indicates Release mode the PCM commands
the TCC to release... ... 2 indicates the PCM has commanded the TCC to
lock... ... 3 or Apply Enable indicates all conditions are met to apply
TCC... ...4 TCC engaged...

Thanks Ragtop:
So if I'm looking at a good Yank (94-96% Eff) it may not be worth it? I figured programming would be a better way than butt-o-meter press the button! Need to look into this a little more, maybe test it out.

Anyone do this and have any suggestions for adjusting the table parameters?

Sonny:
Thanks a bunch, that's just what I was looking for!

Sparky:

I use to have Ed Wright programming and he stuck it in and my car was dying on the top end with 3.23 gears. My trap speed wasn't high enough to take any advantage of it. It knocked me back from the mid 5000s to low 5000s rpm when the goal is to cross at close to 6000 rpms (peak HP). I also got knock retard during lock-up from the intial shudder which probably cost a few HP too.

the only reason i have done it, is that i know of a few that have toasted there trannies doing so... im not sure if it was something else, or if it was lockup switch related...

but maybe on LS1 edit it wouldnt have the same effect as the manual lockup switch
