So whats the deal with the e67 ecus?
Supposedly MEFI5 is the E67 with a different OS.
What kind of secret sauce does mefiburn use? Sounds like the MEFI is a hell of an ecu. can run cable or dbw, 24x or 58x, distributor even..

What camshaft did you guys run??
Well I decided to just buy mefi burn myself. I talked to the owner and nice guy should have it in a couple days ill post the file that I read out.
i dont think you can read out the tune can you.i heard the ecm's are locked from factory and that you have to flash a new tune in to begin playing
When I talked to Bob he said when I get the cable try and read it out it will give me a checksum number and he has all the passwords for the mercruiser mefi stuff. I had asked him the same thing he said not an issue
