So if you all don't know I have a very custom written software for my MKC and no dealership would touch my car. I have transplanted the 2.0 for a 2.3L and with all the transmission problems with the PCM programming in the 2.3L I needed to update the PCM programming. I was able to update the PCM on the first time which worked perfectly. I figured I would also flash the new programming to the FCIM as well because I will get heat when I should get AC (from time to time) so I flashed this module and it failed. I tried multiple times and it kept failing. I had no front controls, radio, airbag lights were on, and many many more issues. I finally figured out a work around to get it to flash correctly! I had a scary couple hours but okay now!
