mefi 3 ecm
In march i repowered my 1999 ebbtide from a 5.0L tbi to a 5.7l tbi.I purchased the engine from michigan motorz and they sent the ecm to marine power in louisanna to have reprogramed .the problem was that one of the two dropped the ball, because marine power can only reprogram to gm specs and the computer was programed to mercruiser specs.I was told they both do it differnet. It would not do anything when hooked up.So michigan motorz sent it to someone else that said they could do it.it now has 5 volt refence signals ,but no signal to the coil or injectors.My question is it really possible to reprogram the mefi 3 to mercruiser specs and if so does anyone know someone who can.

I know AZ Speed and Marine can do it. I hate to pimp them after all the times they f-ed up my boat but I'm sure they are condifent enough to put a stock Merc. program back in that ecu.
