Thanks for your help guys, I managed to work out how to clear the model names and reset M01: to what I am using. I now understand there is no Factory reset or clear for everything. I have managed all the usual settings, DR/EPA/EXP etc and understand most of them. I am running electric 10th offroad - a Durango DEX410, I will experiment more tomorrow at the track. Trying not to be overwelmed with all the adjustments, but most setting are now back to what the manual describes as defaults, and will take it from there.
Thanks again.
Raymond.
