It's been months now since my MGM failed I then ordered a V2 MMM and it failed within seconds of turning it on. But the good news is my MMM V3 just turned up woot woot I have tested it in the car on the bench. It powered up and calibrated as it should and I can't wait to hit the track (when it stops raining).
I need to get a new video up on youtube for all the non believers.
