Default How to force the converter to lockup WOT

Is there anything in particular I need to do in HP Tuners to get the converter to lockup while WOT? I tried just changing the 3rd gear lockup speed but it didn't seem to do the trick...Trying to lock it up at the end of the track. It's a 5 disk lockup, no worries.

I did mine with just the lockup MPH (being sure to
keep the unlock MPH in step). Worked OK on my
Camaro, though I gather there are other platforms
that behave differently.

I would be very surprised if any 3500+ RPM converter
gave you a net gain in acceleration by locking. If
you just need that 500RPM back, to not upshift,
that's another matter, do what you gotta. But you
will probably forego some residual torque multiplication.
