I have a '99 MEFI 3.
Is the MEFI 4 distributor less? I'd love to get rid of the distributor.
Thoughts? Ideas?

I started seeing them show up in model year 2000 Regals at the dealer level. So it's possible they could have been installing them by mid 1999. I think the model year changes around mid June for the boat builders.
A MEFI4b will run an LS2. I believe it's all about getting the right firmware installed.
UMI racing sold the ecu package for this many years ago. It was then sold off to MSD.
Not sure who is selling it now.

OMC had the distibutorless " Spitfire" ignition in the late 80's and early 90's. I would NOT recommend it however.
Which engine do you have?
I would think a call to these people would answer your questions,

You'll need to add a crank trigger and use an L31 distrubutor for a cam sensor. They make a cap that replaces the normal spark plug style cap. You'll only be using it for a cam trigger.
Something like this would work as well.

You can use an LS ecu which is probably cheaper than a MEFI4b. But you don't have to.

L31 which is a sbc Vortec motor '96-'00. Mercury used the same unit in some of their engines.
It has the right output signature to use it for a sync source.
