8hp70 transmission controller?

Does anyone have any experience with the 8hp70 controllers? There’s a couple on the market but I’m hoping someone has used them and can give me a rundown on how user friendly they are. I would like to use the Holley terminator for engine management.
There's HTG GCU & Turbo Lamik ,sound german ,the video is from 8speedAU in queensland Andrew doing the video he is quite knowledgeable on the Tubo Lamik currently it will only work with inputs from the engine at last feedback it will not communicate with the Holley Terminator Xmax due to can buss differences
