MSefi.com read only forum (Jan.15,2018)

Hi ive been lurking around here for a while now while i try and learn what all i will need to get my EFI going.

What were doing is converting our boat to EFI we found that our current intake manifold is ruined and we already had the new multiport EFI manifold and stuff bought for a future conversion.

well a new manifold is $280.00 and well MS for what i think we will need is about 400 so wth spend the little extra and get what we want. we are using a 1986 Tbird manifold on a 1974 ford 302(Rebuilt motor fresh from the shop)

my question is we want to run with the ford edis or a edis system do we need the edis module or will MS operate the coil packs.

also what all will we need

MS which version would it be better for us to get the MS III kit or should we just use the MS II kit
also which boards besides the stim will we need, I'm a little confused on this.

Also i would like to know if anyone has had any luck running a O2 sensor on a boat. With the water cooled exhaust manifolds i cant see how this wont destroy the O2 sensor.


any help so i don't waste cash or don't have to wait to order more parts will help

Thanks

also any links will help too

I'm not completly up on all of the versions of MS, so bear with me.

The MS3 will control the coils directly, It can fire them sequentially if you wanted, you could also set-up sequential injection if you desired to, you would need the MS3X board to do this.

MS2, I can't recall which board version off hand, can control coils as well, but I believe is limited to 4 cyl apps, or 8 cyl wasted spark, which is what EDIS would be anyway. I've seen success and failure stories in fireing the coils directly from the MS, so do your research on that.

A lot of people have had very good success using the EDIS module.

If it was me setting up an MS in a boat (honestly I have a different route I'd take personally, but that's niether here, nor there), I would look at the MS2, using an EDIS module.

You may want to hit up some of the boat forums on the intarweeb, about the O2 question. I've read about some people using one, and some people don't. It seems to be largely based on the actual manifolds being used. It is nice to have that O2 sensor feed back, at least for initial tuning.

My biggest concern would be water proofing the MS, but still keeping it easy to repair, or modify down the road. You might want to consider creating or using a container that the MS lives in, that is sealed off decently from the elements. This would really depend on the boat and how it's set-up in how far you have to go to ensure the electronics stay dry. Keep in mind that even if they don't get wet directly, there is still a large amount of airbourne water, that effects electronics, especially salt water, if you come into contact with that.

Hi.
My bet would be a MS1 with the latest code and EDIS system.
Go with the extra money on a good enclosure for the MS, solid contacts and well made cable harness.
EDIS will save you a heap of problems. And my guess is that the EDIS will work even if you drag it after the boat
in the cables, unless a marlin gets to swallow it.
