In this video I describe how to identify early marine gasoline electronic fuel injection (MEFI) ECM's and show some of our lab engines which we teach on.
93 model year for the 502 big block was first mefi 1. the 320 efi was in the 80 s ( 87 thru 89 ) used basically an outboard ecm that took a special scan tool back then. I do ecm repair everyday
L29 is the mefi 2 . next is MEFI 4 labels the 4 on the sticker on the back. Mefi 3 had Delphi sticker as well. The newest built mefi 4 has AC delco stickers on them. And the 4 has MEFI 4 a and 4 b. Those will be going away as well like MEFI 1 thru 3 did many years ago. I have plenty in here for testing & repair
Hey Ted, would love a video on Volvo evc steering overview. Tips and tricks for EVC steering failure error codes. Fluids up but still getting error of steering failure when trying to plane.
@@omarf4 Omar, Negative. Dealer item only, and the dealership must have a certified tech (who was trained on EVC and Vodia) to use the tool. So you MUST contact a Volvo Penta dealer.
How can you diagnosis mefi 3 for no spark, distributor cap is not crab style, does not have external module only has the magnetic rotor trigger under cap
Hi ted! im from argentina, i need some help. Im having a fuel message on a 6.2 300hp mercruiser, i believe 2006, belongs to a costumer. Is there any way to do a self diagnostic using the clip on the diagnostic conector? Thank you.

Thanks for the info, If I remember correctly we used the Rinda Techmate back then on the 320 as well. That was many moons ago.....

Have you gone through the steering calibration? You need a Vodia tool for that. It could be you have a faulty SUS unit or Resolver issue.
@@tedsmarinerepair8956 can us regular folks get the vodia software and adaptors or does it need dealer?

No sorry scan tool is needed
Whats the First year GM marine engines were fuel injected?
Not positive, around 1987 if my memory serves me right. I went to the first MerCruiser MEFI I 350 EFI Magnum course that year.
I need some help if you could email me that would be great.
