2017 Ford 6.7...which ECM to select???

[LPD Tuning]

Ok, so Im having trouble getting a '17 to read the ECM. I got the TCM to read just fine. Which ECM do I need to select? Forgive my ignorance but for the life of me I have not found anywhere on these forums or the website to determine which ECM is in these trucks. Ive tried TC-1791 and I get the x35 error. Ive Tried 13+ 1794A and get writer response error. Anyone have any ideas? I have the latest Beta update (obviously cause I read the TCM just fine). I was connected to WIFI while attempting also..

I dont like to be connected to anything outside of the vcm cable when reading or flashing. But see if 351c is right.

Make sure you are using the beta software
