Default Lockup convertor in 3rd at WOT using Edit?

Is there anyway to program the computer to lock up the convertor at WOT when I hit third gear using LS1 Edit? Or do I have to use a lock-up switch?

yes. You can do it in the TCC tables.

Go to Transmission Calibration>A4TCC>TCC MPH Threshold look at the 3rd gear Apply threshold and set to your Mph you want this to be.

Or edit the Normal Mode MPH vs TPS% or the
Performance Mode MPH Vs TPS% and edit the 3rd gear lock up at a percent of TPS per step, if it has 255 in every box this is the miles/per/hour the car has to reach before lockup.

That's Cool. How much more trap speed would one pickup in the 1/4?

Trap speed gains from 0 (very efficent converter) to 2 mph.

I'm locking my converter (stock) up using LS1Edit at 75 mph. No numbers on if its helping though. It does seem to pull harder up top. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I know some people lock up the TC at 50 mph in 3rd and 4th.

I might do that, but unlock it at 140mph in 4th.

top speed:I went from 147 stock stall to 152 with the 4k.

when it shifts into 4th, you feel it, not like it's dying, but waking up.

around 50 - 80 mph is fine for use on the dyno depending upon your gears. Dynoing on an unlocked high stall converter is just about worthless from a tuning perspective because the converter shift's extension does not allow you to tune the midrange and results in a skewed rpm & torque readings.

I was at the dyno a couple of days ago.. I had to run up to 70 mph then we started the run...so it wouldn't kick down..Anyway I would lock it from 70mph up..then your readings will be like 70-130mph...or whatever you rev to.

Is it bad for the converter to lock it at WOT?
