Default In need of Delphi MEFI ECM 1623699

Anybody out there know where I can get one of these. Bob at OBD scanned mine and it is fried. If i can't find one at a reasonable price I will probably convert to Carb

Think you need another 9 added
Just info but being a MEFI 3 you can use anyone of these to reflash, can check with Bob, but this is my understanding

16237009 MEFI-3
16237019 MEFI-3
16236999 MEFI-3 * Merc version
12489488 MEFI-3
12489493 MEFI-3

BTW figuring Bob did say yours could not be repaired?

And you can go to a MEFI 4 with a conversion cable, but still need a reflash

Yes that is correct. 16236999 or 16237009. These are the only 2 Bob said are plug and play. I would rather not have to reflash.
Yes mine is unrepairable.
Any help would be greatly appreciated

I would go to carb and call it done. As I mentioned before in your post -- not easy to find and in most cases can be expensive. Mefi 4 conversion too expesive anyways and really nothing to gain. Nothing wrong with a marine carb engine. the 350 mag carb and 454 carb marine engines are porb the most reliable marine engines still running.

Thanks for the response and that looks like it’s going to be the most economical route to proceed with

I spent around 1300-1400 when it was all said and done. New carb intake gaskets and distributor plus labor. Now there is no second-guessing what the issues could come up. My chaparral runs great now with a 500 CFM Two barrel carburetor

I forgot we also had to rework the fuel line and put a low-pressure fuel pump because the throttlebody required a high-pressure fuel pump
