Anyone successfully done it? 
I have a spare ECM coming that is currently a CaTCHER modified unit - and that's OK, if it must stay that way - but if possible, I'd prefer it to be returned to stock, if it can be done purely with a re-flash of the basic programming, rather than electronic surgery.
Anyone have a clue?
