No, I'm pretty sure Techsalvager will still find something to complain about. Probably that he doesn't like the color of the case. Schizophrenia is funny that way.

This looks fantastic. I know its hard to say, but is there a ball park on price and when they will go on sale?

Are you telling me that this unit will do the crank/ cam circuit of a 99, and run the alternator, and everything else the stock ECU would do on a '99 Miata without changing anything internally?

Just out of curiosity, does it use the MS3 'daughter board', or is it an entirely new pcb?

Obviously its an entirely new PCB.

Thirdgen, the MS3 does not control the alternator right now.

The alternator circuit not being inside is the main reason I didn't try out the beta.
Beginning to regret I didn't though :(

I have rudimentary alternator control code to test out when I get the chance.

Target date on or about 1 Jan 2013. Cost will be sub $1200 including 8' harness, SD card, and backup battery. It's going to end up at about the same cost as a MS3 V3.57 + Expander + RTCC + knock module, and MS3 Pro has all of these items all built into a single board solution. We've made a number of improvements to the design as compared to the V3.57 to improve efficiency and reduce heat such as a switching power supply stable below 7V.

It will read the crank / cam sensors of a '99 Miata without changing anything internally, as well as the crank / cam sensors or pretty much any other vehicle in existence.

Ditto for aircon. This has been a native function of the MS3 for a while now.


Alternator control as we have traditionally been doing it is sort of an application-specific hack. I believe that the goal is to use one of the many spare PWM outputs of the ECU, and configure it such that BattV is used as the X-axis variable in the map. As Ben said, this is in the early test stages, but will obviously be a reality quite soon. The Miata isn't the only vehicle with an ECU-controlled alternator these days, so it's high on the list.

EDIT: I just did some browsing of the dev board, and apparently this is already implemented in the latest Alpha code. So there you go.

Yup. Not only is it entirely new, but it bears virtually no resemblance at all to any existing MS product.

Inside is a single circuit board which directly hosts the CPU, as well as the connectors and all of the other circuitry. Apart from the two main connectors and what appears to be a bootloader / test header, it is 100% surface-mount, with components mounted to both the top and bottom surfaces, just like a "real" PCB. I spent some time digging around and inspecting the physical construction while I had it open, and I was pretty impressed. No jumper wire at all, no cut traces, no solder bridges...

It's obvious that they got the PCB design right even before the beta run. Heck, at Harris we're "professionals" (we build audio consoles that cost $15-$20,000) and we usually ship products to customers with jumper wire in them for at least the first few months of any new design.

The MS3Pro, by comparison, is a universal Über-ECU designed to work with pretty much anything that uses spark plugs to ignite gasoline, without requiring all of the application-specific internal hacking (aka, mods) that have always been necessary in the past. In terms of the build quality and completeness, it's well-poised to compete against the "big boy" ECUs from companies such as Hydra, Bosch, Adaptronic, Electromotive, AEM, etc., and appeal to buyers who, in the past, may have viewed the MegaSquirt family as more of a hobbyist toy / science-fair project than a "real" ECU.
I get that and I wasn't by any means knocking (pun intended) on either Rev or DIY. This has however complicated my decision on ECUs. If I'm going to spend ~1k on an MS3, I want it to be the most badass thing you can buy ATM, and preferably the last ECU I'll ever buy. Might as well toss a coin at this point

Looking forward to this unit coming out! Good thing I installed my MS3/MS3x on another car instead of my race car! Can this be used in the engine compartment?

I have split off the discussion on alternator control into its own thread: https://www.miataturbo.net/megasquir...ern-era-69803/

Does this version finally have separate grounds for high current loads and the inputs?
