That's cool that you can use the VSS to tell the Terminator what the vehicle speed is.
Here is a link to the software we are using for the current Powertrain Control Solutions controller (which is an off the shelf software that's also branded and used by FAST TCU).
https://www.powertraincontr...0_Tuning-Install.exe
It doesn't come with any .bin files pre-installed, we had to get the base file through the dealer. Here is one of our latest attempts:
https://drive.google.com/fi.../view?usp=drive_link
When you open the .bin, in order to see all the granular settings, in the menu bar click on "Software Setup" > "Tuning Mode" > "Advanced" (it defaults to basic everytime).
The drill down menu on the left will change. To see the stuff about the speedometer and various settings the TCU can use to watch vehicle speed, expand "Hardward Setup" > "Speeds". Then double click on "Speed input selections" and "speed input pulses". Feel free to check out all the other stuff in there, too!

I’ll try and take a look in the next few days and see if I can figure anything out.

Wow! Thank you, I appreciate that. I figured you were just curious about the differences in tuning ability and how the two TCUs varied.

Picked up my Black Friday purchase today. This is based on the converter I had in the 4T65 previously. Should allow me to spool the turbo on the line, but should couple slightly better.
Drivetrain is currently out of the car so I can fix my leaking head studs and install the converter.

Nice! Is that a Precision Industries torque converter? I don't know how common it is for those to be painted purple.
They took the 'guts' of the 4T80 and put it inside a 4T65 shell for me, so that I could have a billet case to help prevent ballooning / case-kaboom.

It is a precision. They built my 4t65 converter for use with the o-ring less GM Racing input shaft. Took the data I had from that converter and made this one.
Stock 4T80 converter I could get 1800 rpm before pushing through brakes, no turbo spooling at that speed. This should go to 3000-3200 like the 4t65 one I had, but should couple a bit better at redline.
Saw an email this morning that precision has been purchased by a holding company that also owns pro-torque.

Got the drivetrain back in the car after installing the new converter, cleaning up some vacuum/coolant hoses and sealing the old engine wiring harness pass through on the fire wall. Leaking head studs were swapped out for new stock head bolts. Installed a pressure transducer on transmission line pressure port and wired that up to the Holley. Installed a new eBay Air to water intercooler to replace my leaking precision. Finished the wastegate pipe, wrapped the rest of the exhaust and put a blanket on the wastegate. Engine bay is pretty well finished up now. I will probably put an upper dog bone mount in to take some of the torque off the subframe, and brace the exhaust near the turbo to prevent cracking. Need to finish putting the interior back together, and finish the mounting the ballasts to complete the embrace racing headlight install. Going to finish idle and off idle tuning then look at getting it on dyno to do drivability and WOT.
Feels pretty good to have the car this close to complete, this summer it should hit the road for the first time since 2016.

Haven’t shared any pictures of the car since I started wrapping it last fall. Now that it has been seen in public, the cats out of the bag. Huge amount of work has gone into bringing this back to the street. It has been surreal driving it again after so long.
