Looks like cool build. Question, why the Motec? Top of the line ECU for sure. What does that unit bring to the table that you can't do with a MS?
DBW, traction control and native integration for a sequential trans are the main features. There are a lot more technical features that will be benefitial during the tuning process but in a nutshell you are comparing a motorsport grade management system versus a tuner solution.

So you'll be doing dbw on a bp? And running seq trans?

Yes, I reviewed the MoTec M130 specs (and price, ouch) and saw these features listed. Not sure they are applicable to this build.
I am curious as to your statement..." There are a lot more technical features that will be beneficial during the tuning process...".
Can you elaborate?

Is this your BIAS because of a quick Google search or previous experience about tuning cars with this engine management to notice the technical difference? Have you also investigated the firmware packages extending up to the developer features?
I don't see any bias, he was just asking a question. We all know the motec is a serious piece of hardware, we're just curious if you're really putting it to use in a miata, and how.

Most of us get that Motec is a better platform at almost 2x the cost. The main question is what additional benefits are there that makes it worthwhile? Is a Miata able to utilize the additional inputs/outputs that Motec provides that MS does not? You said the tuning aspect is better. What makes it better? Is it the firmware that Motec provides? Better coding to make things run better? Not being biased, just genuinely curious.
Let me point out a personal opinion before we derailed away from the point of this thread. Just because you can get a solution to work doesn't necessarily mean it's the best and it should be a universal application. Hardware characteristics on a Motec unit and also Firmware features is a topic that deserves its own thread for those that are so curious. I would suggest reading the complete public documentation manual for further judgment in terms of ROI; it's fun if you like technical things.
Anyhow, one of the main reasons why I picked up a Motec unit is because I can apply traction control strategies by utilizing a combination of wheel and driveshaft speed sensors. I plan to import raw data from the Motec unit into Matlab and implement a piece of code for slip values showing the highest acceleration values at different throttle position sensors. You can also extend this by adding GPS positioning data to control boost control settings and cross reference them with your TC mapping. I don't plan to meet a specific racing criteria for this build. In all honesty, it's a fun experimental project for pure joy. I have always been curious about the tech packages found in top level motorsports cars. It's a fascinating and the fact that I can't afford any of that got me annoyed for many years so I figured why not bring my ghetto version of it into a car I own.
I could go on and on about describing other features where megasquirt falls behind but I don't want to end up sounding like a sales dude bashing on MS. I have been told moderators are pretty agressive on this board so I don't want to turn this thread into what could look like a marketing campaign. I noticed the dude's entry with the cool tubular turbo manifold picture is already gone.
In term of the powertrain, I originally ordered a custom Quaife sequential for my ND. My ND won't be finished for a very long time since I plan to retrofit a M150 but I don't know a lot about DI implementation. It took over a year to fully implement the mapping for a turbo kit via the OEM ECU. I am honestly not confident on the project so I figure take my sweet *** time and order a spare bellhousing adapter and retrofit the same transmission into my MSM.
This is one of the times i'd hope the mods won't bash you for talking about the additional features Motech has that MS does not. I can't imagine a majority of us over here would spend the extra dough for it even if it was worthwhile...Sticker shock when I saw it.

I spent some time running an initial mock up for the turbo manifold. I am quite focused on making this setup removable on the fly. I am hoping to come across quick disconnect fittings for the turbo lines so the whole setup including the manifold, downpipe and intake pipe comes out on the fly.
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!
