Can a DDT diagnose a bad ecu?
Did Mercury come out with a new DDT for the 4 stroke or is it the same DDT with new software?
Thanks for your time..

Not sure if it can find a bad ecu....but the ddt is now software based - laptop - the Mercury software is only available to dealers. You can buy aftermarket. Check Diacom. Maybe Don can help you with how to check your ecu. Please post what your engine is doing or not doing.
