i would like to try and lock the torque converter
in 3rd gear and see if it helps my mph at the track .

i see in the constant table "tcc unlock prevention
speed threshold" i am unsure of what this accomplishes
and there are 2 tables for lockup and 2 for unlock
mph versus tps.
the way i read it since i cannot enter a value of greater
than 100% in the unlock tables any time i go to
full throttle it will unlock the onverter . is this correct?

I'll take a stab at it. I have not seen anywhere to control lockup the way you want.

Grounding the ALDL terminal "F" will lock the converter. So if you tap that wire and run it through a momantary on pushbutton switch to ground and attatch it to your shifter so you can push it with your thumb you can lock the converter at any time.

Be carefull though, the clutch won't take alot of abuse.

 

TCC unlock prevention speed means that at that speed and above, the TCC will not be unlocked. In other words, if it is set at 75mph, at 75 mph and above, the TCC will be locked, whether at WOT or not.

IIRC, stock it is set at 75mph, you just might not notice it lock if you have a stock converter.
