HI all
I have a 2005 Sea Ray 240 SunDeck with a 5.0L Bravo MPI. engine serial no. OW068236.
I replaced the engine block with a 5.7L (MAG 350) from Michigan Motorz.
I sold my original 5L Motorola ECM with the part no. 865836 with a serial no. of W9010VI1 and manufacture date of 08-10-2004.
I was told that this wouldn't be compatible and I would need to either reflash or get a new ECM to match the specs of the 5.7 MAG 350. I bought a 350 MAG Bravo ECM0713 dated 02-27-2013 (8M2001111) (8M2003678) (A30004IS) bar codes. I did this thinking it would work, however, the motor starts up , runs for a few seconds and dies. I've been told now that there are many different compatibilities for certain years and certain applications and that a 2013 ECM would not work with my new system.
Can anyone tell me what I need here? What is actually compatible with the software on the ECM that will work with my 2004-05 5L - now a 2014 5.7 block. I'm gonna guess the block has nothing to do with it as far as anything ether than it's now a 5.7.
I've called a few places and no one seems to want to give me the answer I need. So, here we are.
