Hi Justin,
I flash FEM on the bench here, worked great. All of them for Auto cars though. I did have one FEM though, that came from a manual car, that didn't allow me to flash it. On this one it doesn't see elv, so can't switch on ignition. Let's see what workaround is possible for this one. I might just grab an elv from a car to switch FEM on my bench and see if that resolves the issue. Not sure if an E series elv emulator will work, maybe I can try that as well.
Unlocking FEM, realistically, can't be done while in the car anyway; it has to be done on bench. So we need to figure out a way to get past this.
