That Elmer billet merge/flange is definitely a beautiful piece but it's also big $$$ (250euro). I'm going with this piece from Treadstone. Investment cast stainless. I hope I don't regret my decision!
Which gearbox will you run? The Megasquirt has been working with a lot of gearboxes, including Samsonas and other very high end gearboxes.
Can MS do closed loop? If not then meh.
Awesome build by the way. Subscribing. I'd like to do Motec in my RX8 one day, the traction control is awesome and GPS based control would be cool to play with. Maybe active aero.
I have not seen an application so far where the gearbox wouldn't work properly with the MS3, like I said, with gearboxes from Samsonas, Sadev and Quaife.

Kind of dodged the question there eh?
I'll assume that it's a basic ignition/fuel cut on a time delay. Also I don't think you can input a raw strain guage 0-5v signal either if I was reading that correctly in the Quaife thread. One other thing that Motec can do is a power reduction for shifts instead of an abrupt cut as well.
This website actually explains it pretty well with data logs and everything.

Are you gonna run a custom intake manifold? I noticed you bought intake flanges. If so, I don't know much about what makes a "well designed" intake manifold considered well designed. What's the primary benefit compared to a over the shelf manifold? Either-way, i'm looking forward to the fabrication of it.

I think the over the shelf manifolds outcase poor design philosophies that make everything else around it hard to service. Also, I don't plan to use a Miata TB. Fabrication will need to take place at some stage.
cool stuff! Check out a VW DBW throttle body from the 1.8T. I had it on my old PT car. Bolts up to a stock BP manifold relatively easily. I know you would rather not use a stock manifold..
also check out the life racing ecu for the ND. DI control and all your development stuff you have to pay for in motec is free!
custom 2d and 3D maps for what ever your big or in my case small brain can think of.
My plan IF I ever get my car settled and if I don't sell it would be C6 or Volvo V70 pedal with a audi (Bosch 0280 750 009) throttle body pared w/ skunk 2 manifold. Unneeded and unnecessary but seems fun to add.

for a big power build and DBW, get something like a VDO throttle body from a chysler/dodge hemi. they are 80mm but with dbw that really doesn't matter. you can program throttle opening over rpm so it really doesn't matter how big it is if the PID's are good. 2500rpm you will only need like 20% throttle opening (set that to 90% pedal) and linear down to 0 from there... perfectly drivable car with zero chance of intake losses and advanced filling of the plenum when you are fully open.
That's what I purchased to use on an old project. they don't seem to have any issues from what I could read.
point of the post was more along the lines of - - get the largest throttle body, there are almost no negative impacts from a larger TB when you go dbw being that you can tune it to how you like to drive and tune throttle plate over rpm against throttle pedal position so its still drivable - -
I narrowed down into two options in terms of the DBW setup because I already have the calibration files, GM style or a CRV unit. The GM style is pretty fast between 10-90% and their response time is somewhere around 20ms. I will do more digging when I am the stage to make the call.

Fine idle control is almost impossible on large throttle bodies on small engines.
