I say it is a bad idea because it is alot of work. Alot of work that no-one I know of has done around here. If you run into a problem you might not be able to find an answer. Think of the ecu situation like this: If Honda took the time to make a seperate ecu for the automatics and spend a hell of alot of money developing it I'd run it. Especially since you should be able to pick it up for less than $50.
