303Skier Posted November 8, 2016 Share Posted November 8, 2016 Trying to help my dad out, he has a 94 MC PS190 and the ECM went kaput on it. Plugged it up to PC and there is nothing there. Does anyone know where to get one or how to get it fixed? It has the 350 TBI. Tanks Ballers! Link to comment Share on other sites More sharing options...

303Skier Posted November 8, 2016 Author Share Posted November 8, 2016 @dtm8119 My dad found this site already. Wonder if this is the only route? Does anyone have a ECM sitting around collecting dust? Link to comment Share on other sites More sharing options...
Baller_ Jody_Seal Posted November 8, 2016 Baller_ Share Posted November 8, 2016 MEFI 3 Indmar. Good luck. I would start with the known old time MasterCraft dealers or dealers that might have sold MC in that time period. Rambo. Bennetts. Also you can go to Team talk and put some feelers out.

Baller BraceMaker Posted November 8, 2016 Baller Share Posted November 8, 2016 Isn't the 94 mefi-1? Link to comment Share on other sites More sharing options...
Baller Fine409 Posted November 8, 2016 Baller Share Posted November 8, 2016 I had a 2002 Malibu where the ECM went out and it was version 2. Those guys in CA are where I got my replacement from. I know they are really tough to find Link to comment Share on other sites More sharing options...
Baller oldjeep Posted November 9, 2016 Baller Share Posted November 9, 2016 Couple MEFI 1 ecm on ebay here: MEFI-1-Reprogramable-ECM-16189069-V8-502-454-350 ECM-16234539-Mercruiser-MEFI-1-V8-502-454-350 Link to comment Share on other sites More sharing options...
303Skier Posted November 9, 2016 Author Share Posted November 9, 2016 @oldjeep Does that boat use a MEFI 1 or 3? Also if we buy this ECM do we still need to get it reprogrammed? Link to comment Share on other sites More sharing options...
Baller Fine409 Posted November 9, 2016 Baller Share Posted November 9, 2016 @303Skier there should be a label on the ECM that shows what part number it is, so you can figure out what MEFI version you have. I'm not sure on the reprogramming question... Link to comment Share on other sites More sharing options...
Baller oldjeep Posted November 9, 2016 Baller Share Posted November 9, 2016 @303Skier - I'm going to assume MEFI 1 since 94 pretty much marks the beginning of Marine fuel injection But if you look at this link it shows the GM part numbers and a visual identification guide https://obd2allinone.com/mefitune.asp As far as reprogramming that would be a question about if MC was using a custom tune or whatever GM was providing with the bobtail engines.

Baller BraceMaker Posted November 9, 2016 Baller Share Posted November 9, 2016 Believe it's got a tune - however many folks complain factory dumps too much fuel. Link to comment Share on other sites More sharing options...
303Skier Posted November 10, 2016 Author Share Posted November 10, 2016 Thanks for the help guys! I will see what I can find. I think we are going to try and have it reprogrammed first. Then if that doesn't work...the hunt is on. Link to comment Share on other sites More sharing options...
