Well, after googleing extensively, and talking to the Rep who sold me mine, who is an outboard expert, i have to disagree with you Hirk.Doesnt mean you are wrong, just what i understand as fact, is different from yours.He told me they do operate exactly like your cars ecu,but less complicated.
But thats all i will say about it.
I hate it when these threads turn into never ending arguements.
Cheers
