According to your setup at 100% wot position your converter will not lock up in 3rd gear til 213 mph, if you know of any other way I'm open to all suggestions

If I change those cells it will lock at whatever speed I put in there. I just showed that table for example.
I dont lock my corvette in 3rd because I have a single disk convertor. My truck locks in 3rd with a triple disk just fine by adjusting this table.

Here is what it would look like in HPtuners. This would lock the TC at 100 mph in 3rd gear at WOT. My car shifts to 3rd around 95 mph, so you would have to adjust the WOT lockup as well as normal tables to your desired 3rd gear lock speed.

Interesting post.
I assume that if you reprogram the 3rd gear lockup speed you would wish to let it get to third for just a bit before locking the clutch? In other words, don't set both for the same number?
Also, I bought a Yank SS3600 NIB from a forum member here. I believe the clutch (single disc) in these is better than stock. I believe I will ask Yank if it would be appropriate to lock this in 3rd. I imagine it depends on the power level of the engine along with the design of the clutch.
At present, my car is stock. So this is in the future.

I have a 3 disc Vigilante and tried lockup at the track. I never could get it to work and gave up. I used the table shown above "TCC Apply/Release Speed Normal", and it didn't lock. I also installed a switch that commands locks up on the street, but it didn't lock at WOT.
I don't have that WOT "Full Throttle Apply/Release Normal" table. What version HPT is that, and it's your C5 right?

I still am going to try it out , Steve Jr says I have enough hp/tq at that power range to push it through third gear.

Yeah even with a switch mine didn't work. I threw the switch at like 110mph, and it never locked during the pass, but did lock on the return road.
Here's what I did: switch to ground, red connector on the pcm in pin 42
I targeted 5200rpm in 3rd, and I go thru the traps about 6800.

I am running HPtuners 2.23 beta.
Normally TCC lock issues are a result of misfire events, and cured by doubling those values in the engine diag section. Try doubling every value that is not maxed out already.
After that add the TCC mode and TCC PWM Duty Cycle pids to your scanner for your runs. Of course there are some things we have no controll over such as minimum temp, etc.
I am not aware of anything special about Corvettes that would not allow the convertor to lock at WOT.

Hmm, I checked my tune in 2.23 beta and there's still no TCC WOT table. That side of the window is just blank. Are the pictures in post #5 possibly from the tune in your truck? If it's your C5, then maybe something different between model years. My tune came from a 2002.

Dan we talked about this before-Yank stalls are not built for lockup-especially not from the converter man rebuild.
You have to understand-lock up's were designed for hi horsepower cars-and will more than likely hurt your times and performance if you don't have the power or torque to take advantage of it.
The proper converter will ET and MPH the car.
I went from the Vig to purpose built Coan-the results speak for themselves.
But then again-what do I know?

Having said that, Chris, it sounds like you might benefit from WOT lockup given your RPM through the traps. Log those PIDs and we will see what is going on.

I'm interested in looking if RonSSNova or SLVRCPE would send me your HPT, to see if the TCC WOT shows up here? Thanks in advance.

Another Hmmm
Maybe yeah, but I'm ok running unlocked. It went 145.9mph Saturday night, and Arun will verify his experience with lockup it toasted a 5 disc converter in about 10 passes.

Chris, PM me your email and I will send one of my tunes. I am thinking the trans segment is diff from 00 to 02, so mine should show up as pictured.
On a side note my converter builder taunts for a break at any power level. I have not heard of it happening..
