Yeah, I might be able to find out what all parts are needed, etc. Actually, and I don't want to get anyone's hopes up prematurely, as it's probably at least a year off or so, but my friend and his other brother are currently working on a piggyback ECU that'll control injectors, ignition and all sorts of other cool stuff you can think of. They've already got the boards and cases and have successfully got the injector drivers working in basic form. They've also got one working on an RX-7 Turbo II right now as a fuel-cut controller, to allow it to run higher-than-stock boost pressures.
Right now, the ECU only drives low-impendance injectors, but they already know of the potentially big Miata market if they incorporated a piggyback fuel controller, AFM delete option (by way of a simulated circuit through a MAP sensor, TPS, etc.) or an AFM-to-MAF convert , wideband autotuning, O2 clamp, ignition control (or at least the ability to pull timing, a la Bipes), water injector control via RPM, injector duty cycle, pressure sensor, MAP sensor, etc. The architecture is pretty open-ended, so really the possibilities are endless...they'll entertain whatever ideas people have if the market's profitable.
We've got some fun times planned ahead

Well, my friends' piggyback would probably end up costing more than MS, at least a basic MS with no ignition controls, simply because it's using much more advanced hardware. It'd probably be more in line with the price of the e-Manage Ultimate.

ok time to spam some more stuff I found interesting about the MS:
RE: spark
Like I have said a few times I think the miata cas and the DSM cas are the same
I read threw the LONG *** post about using the DSM cas to control spark with MS. If anybody wants to take a look its here
The jist of it many were able to get fuel and spark going with limited or no modifcations needed. The MSnS extra code (found here)
Add's a lot of great features take a look. I really want to order the parts for the MS or buy a prebuilt one when i have the money...
Oh ya the guy that already has the MS on miata.net said he is going to try to add spark sometime around xmas/ thanksgiving. I am keeping my eyes peeled for it.
RE: spark
So you should be able to use the second wheel decoder with no problems, following my posts about the DSMs, and we did confirm that the miata power transistors are triggered by a 5v pulse from the factory ECU - so the Neon output mods are what you need to trigger the coilpacks.
All you need to use the DSM cas is 2 pullup resistors and the extra code installed. Then you configure for wheel trigger, if the cas your useing is the same as a DSM then the trigger angle is 76.
Hints: You need a resistor/extra input on pin 11 (see megasquirt.sf.net, go to the extra section, read), and our coils have built- in igniters- no ignition drivers or modules are needed for miatae.

I'll keep everyone posted on excactly how to make this happen so everyone can squit.
