Hello, I’m in the process of fitting a TCU replacement into my 2015 fusion energi titanium model. I have the TCU (KT1T-14G087-FK) and have downgraded it to JL3T firmware since I had seen this worked for some others and I am aware usually the H series is used for Energi/Hybrid but I already had this part around. I have also already sync 3 swapped this vehicle, it is a 2022 manufacture date unit, and I have set the asbuilt to see the TCU. Not sure what I am missing here but I’ve followed the guide the best I can and it will succesfully go through all of the auth modes but I can never get it to authorize on the app. It will just say mobile features unavailable. Any help is appreciated. If this isnt the correct place to post this I apologize, new to the forum and how it works.
