I just received a upgraded ECM for a 2020 F250 I am working on, installed the ECM, truck starts and runs fine. I went to read the stock file to save before flashing, it will only auto populate the TCM, I have to choose the ECM in the listing. When I click read, it will get to the point it wants me to shut the key off for 3 seconds then back on, when i power back up and click "OK" it fails the read.
So, I tried to just flash the modified file and when it comes to licensing, I have 4 available credits and it will list the ECM controller description but instead of being able to select a licensing option it just has "Do Not". Does this sound like an issue with the ECM itself not being correctly modified?
I am using the latest Beta software and also a MPVI3 with the firmware updated the current.
Thanks
