ECU converter 200r4 lock up control

I did a ton of research and the compushift mini is the best out there in my opinion... I had a painless lockup kit but I sold it on eBay and got the compushift. I have an older version in my square body truck with a 700r4 with a digital display and keypad, looks like they've upgraded it to Bluetooth control. It works fantastic.
What sets it apart from the others is that it takes into consideration the throttle position (with a pressure sensor in the transmission or tap the throttle position sensor if you have efi) and speed.

[Disclaimer]: I realize this doesn't help those looking for "standalone (non ecu)" TCC lockup control, but wanted to share in cases where you have gone EFI (in my case Holley EFI) you have some really cool control of various inputs/outputs for things like this (and lots of others). My config uses an ground (-) output, and is set up to look at several sensor inputs, and also the 4th gear switched input from 700R4 trans to decide when to apply the TCC.
What I also did was configure a "TIMER" so that when ALL the conditions are met, it then also waits 3.5 secs before actually applying the TCC. A lot of simple 4th gear triggered setups will come on immediately after upshift to 4th, and then you get that chug-chug at certain low speeds, or moderate acceleration driving.
Having the TPS, MAP, RPM and Vehicle Speed all being considered allows you to get the functionality very close to factory (oem ecu) so you can tailor it to your type of driving habits and still be sure it's locked up (and releases) the way you want it. For example, it's nice that I could be cruising at about 65MPH, TCC engaged, then a slight increase in TPS to above 15% will release it and give me the added acceleration almost like a downshift without actually downshifting from 4th to 3rd.
You can see how much you can customize in screen shots below.
Here's my setup in case anyone's interested:

When I get back to the house I'll take some photos for you - which should be next weekend. I have it mounted inside my glove box with Velcro tape
Edit:
I found a picture on my phone and attached, but I'll get some better ones of the speed and pressure sensors

You disconnect the TV cable from the carb or throttle body and operate (pull by hand) the TV cable from 0 - 100% while the compushift is in calibration mode. It gets the throttle position reading from the pressure sensor in the transmission
