They have already started putting the 4's on the procharger and whipple set up.It should not be hard to find a stock map.
If ya find a 3 its going to have to be remapped anyway.
There is also 2 different #3's
Ck with Mark at Precision Marine in La 504-469-7463 his is having the harness made for them also.

I'm pretty sure I have at least a couple of mefi 3's and can flash them for whatever stock program you need. $500 each including the old ones as trade in. Contact me at [email protected] if you'd like.

I called Mark today to discuss this. He said that he should be able to help but he believed that there was a slight software difference between the outdrive model and inboard model. I also called a Mercury dealer like cobra marty and outdrive man said and he gave me the MEFI-4 update kit part numbers for these engines. I assume the updated ECM's will have the proper maps already flashed into them. The only question now is at what price?

Maghag, Did you ever sort out your ECU problem? Is there a physical difference between the MEFI3 and the MEFI4? Do you still have your bad MEFI3 boxes? I might be interested. Thanks, Marty.

No External Physical Differance Just The J-1 And J-2 Connectors Are Pinned Differently. More Than A few hundred Per Kit Is Highway Robery Merc Reman Sells These Kits Very Cheap as far as boat parts go
