The Basic MS3 is (functionality wise) like an MS3X/MS3X combo, but it also has upgraded hardware components and the required digital alternator control/smart battery light for the 99-05. It is a direct fit for any 90-05 Miata.

ms3x is the basic offering from B&G. This is typically a v3.0 mainboard, a ms3 daughterboard and a ms3x expander board.

this MS3 basic from Rev, is the same thing, but he designed his own expander board to build better circuits into it. Still a v3.0 mainboard and still a ms3 daughterboard.

There is little difference between the two. (Rev please correct me if I'm wrong)


the MS3 enhanced is something Reverant has designed from the ground up using his own PCB for the ms3 or ms2 daughterboard, with custom firmware to match. This comes with hardware and firmware improvements. He's working on a licensing deal to get this offering out to market.


Eeverything built by Reverant is a PNP and you can deal with him directly to customize your build or discuss the vairous options in megasquirts that he can assemble for you.

For those of us out of the loop, what features will the enhanced MS3 have over the basic?

cappuccino maker.

If you are not interested in the knock and RTC modules, then I dont think you will be interested in any of the other features as well.

What's RTC used for?

Time stamps on SD card datalogging.

for the cappuccino machine...it needs a timer.

... meanwhile a godless soul just waits in a corner like an orphan in tatters..

ERFor us ecu retards, what are some key different FEATURES (relevent to turbo miiatas) this has compared to the ms3x expansion card? Brain said this one was "better" but how is it better?

-rev plugs straight in
-rev has alternator switch for later models built in
-ms3x has contols for more injectors (not really relevant to the average build)
-???

Here's a comparison sheet (Basic MS2 - Enhanced MS2 - Basic MS3 - MS3/MS3X - Enhanced MS3)

MS Labs ECU Comparison Sheet

So - where is the "Enhanced MS3 - Now available from MS Labs!" - Thread... :yippee:

The basic unit has many more features than I had realized. What a bargain. What an amazing bargain.

Dimitris, there are footnotes missing from the chart, btw.

No footnotes.

For example:

VSS VR input(s): Y (2)

This means Yes, two of them.

SO MUCH WIN! Thank you Rev! :love:

What does the * stand for in your chart? Primarily looking at the one on the Basic MS3 under the "Full A/C Support" column?

In that specific case it means "partial" (in other cases it means conditional etc). I consider the A/C system in the MS3 incomplete and it lacks several important features. For instance, there is no minimum or maximum RPM for the A/C operation, adjustable time delay for each fan and the A/C clutch.

Thanks, I was wondering what the difference between "A/C Compressor output" + "A/C Switch input" vs "Full A/C Support" and likewise for power steering because I am a girly man with T-Rex arms. I guess I will just have to wait.
