Hello again, just curious if you can use a generic automotive scanner on an 2004 5.7 fuel injected marine power engine. i have used a marine scanner on a 502 gm crate motor in a truck before. If possible what connector would i use because i have acess to quite a few different scanners from friends. The 502 crate engine had a simple mef system very similiar to what is used on marine applications with all the same systems and the computer was mounted on the intake. I know this particular system is all gm componnents. Has any one had success doing this?
