Someone with a set-up like that has fancier toys than I do! Sure, if someone feels they're up to the installation, I'll cheerfully sell them just the board. This would however result in a NO WARRANTY situation on the assembly; I would still warrant the board itself, of course.

Agreed, but wasn't the now buried Sequencer a MicroSquirt on steroids. Never knew why that didn't get rolling.

It wasn't archaic, just a clever use of angled rubber bushes and a pivot, and elegantly simplistic. Should work well in a lighter car.

The Sequencer ended up being less capable than MS3 and more complicated from a programming and setup standpoint. A number of its design features ended up being spun off into the MS3-Pro, including its power supply circuit and the double-sized MicroSquirt case. Currently the Sequencer design has been mothballed, but it may be brought back if they find some particular niche that it fills better than the existing lineup.

I didn't realise that, and I have just looked on your website and seen the MS3 Module Board, now that's a very nice bit of kit.
Just a little too pricey for my projects, and a big step up from a baseline $250 Module Board, but wow its got a great feature set.
My thoughts after seeing this, there should ideally be a board that was situated halfway in this space, lurking around the sub $500 price point, that offered capabilities somewhere between these two module boards.

I agree. A 4-cylinder MS3 module without the output, ignition and injector drivers but with the basic input circuits, micro SD card, RTC and power supply in a size no bigger than the Microsquirt module would be great. The other circuits would be on the carrier board with a connector and the circuits used could be chosen for the application instead of having to live with the module circuits or work around what was imposed.
I too would be interested in a microsquirt sized 4 channel fuel device. Would it be possible to re purpose the 3rd and 4th ignition channels for injectors on the micro module? Then build injector drivers instead of ignition.

You can already do that on the module. EDIT: See how Jean explained it below.

You can't repurpose the ignition channels. And if you're talking about the Microsquirt module (not the cased version) you can already have 4 injector channels by using PT6 and PT7 and adding the needed drivers. It is done (or an option) on almost all the Microsquirt module-based units including my own.
Ah ok. I see that now. I remembered in correctly that they where used for ignition. I can't use them though because I'm running a stepper driver. I do seem to recall seeing someone has a pwm to stepper add on now though. That might work. Hmmmm

With recents firmware, Stepper motor can use some others pin than PT6 & PT7. So you can have 4 inj outputs & IAC at same time.
The big benefit with MS3 firmware is VVT which is more and more used and can't be driven by MS2 firmware.
A not too expensive with sequential 4 inj + 4 ing + VVT will be a good choice in France. When users have this kind of setup (and there is a lot), they buy an chanlenger C6 ECU from skynam for a little less than an MS3pro. This ECU is far less capable than MS3pro, but feed their needs.
I can supply, repair or upgrade Megasquirts in FRANCE.
Thanks to this thread, in which I participated more than a year ago, I began offering MicroSquirt to my clients instead of the usual MS unit and have got nothing but positive results and a better image from people that know nothing about MS and find that the MicroSquirt looks and is a more professional looking product, and needs no modding at all to get working.
But I still think, as I said before in thi thread, that there is a product missing in the "pro" line and my wish is still that you guys want to consider building somerhing like that. A product for the people that consider a MS3Pro a bit overkill and a MicroSquirt a bit lacking. My wish is a MicroSquirt based product with 4 fuel outputs, 4 logic spark outputs, same tach inputs as the MS, two pwm outputs and a few i/o. That would be a killer product, specially for the 4 cyl crowd.

I built one: http://forum.jbperf.com/viewtopic.php?f ... t=20#p3706. But the response has been underwhelming and I did not pursue that further. People want an MS3 based product (or think they need to) and there is no way to do the same thing with what is available (the MS3-Pro module is too big). And there seems to be no interest in granting a license to build one (at least not to me).
The question is whether the 4-cylinder version would be significantly cheaper than the MS3 Pro, and if the resulting product would be much smaller. For what it does, the MS3 pro compares favorably with the shrunk and restricted versions of the competition.
I'm not that advanced a user, but I use a lot of the MS3-only features, the ruggedized MS2 would not be an option.

I like that idea in concept too, but I think you have identified the main problem, it might end up being 90% the same and basically the same cost, so in the end it wouldn't make a lot of sense to sell at a lower price.
