This thread goes over it pretty well. Are you trying to apply this to your own work? I could guide you on that depending on your goals.
The main downside of going DBW Single Blade TB is that you lose the functionality of the Primary/Secondary control via the Factory FC/FD throttle blade system. So my approach was to control the FD Upper Intake Manifold to do just that using the vacuum actuated flappers to control Primary/Secondary airflow.
DBW doesn't really have a TPS, per say. It's Throttle Applied on the Pedal Assembly and Throttle Body Demanded Angle. That curve can be built out to do anything.
I also don't have a single MAP sensor. I'm using what's called Throttle Mass Flow by grabbing data from two MAP sensors, one pre-TB, one post-TB to evaluate transient fueling airflow needs nearly instantaneously via Navier Stokes equation. My car is also comparing MAP vs. BAP (Barometric) and compensating for EMAP which directly effects o2 sensor control. Sounds complex, it's a lot of sensors, but the point is to give the computer as much data as possible and let it do the hard work.

Manifold Design is mocked up. Here's where she will sit. Finally seeing some progress here. Really happy with the results.
22" Total Runner Length from Exhaust Flange to T4 Gasket using the 2.157" ID Sch10 Pipe.
Ignore this angle. The turbo is mounted nearly parallel to the car's body. Might be able to add a bit more height to get that last bit of exhaust manifold runner length too.

Excuse the poorly written answer, I'm absolutely exhausted. New 7am-6pm job, spending time at fabrication for a couple hours a day, and prepping Full-Race and a few other companies for SEMA. Things are WILD right now.
Yeah, LHD has a TON of room compared to the RHD guys. Your spark plug changes are nice though! :P

Oops, I Forgot How to Upload High Quality on Rx7Club. FIXED!
So, here we are... #FractalFB's Exhaust Manifold. Better start brewing up that Haterade... We're only going to make 500whp.

Thanks for the support.
The proposed exhaust setup so far:
Should be absolutely bitchin' and relatively quiet, while NOT reducing a bunch of power.
Laughing my *** off at these Dahm videos. I'll catch some of you at SEMA... #TeamNoSleep #NoSponsors #SixJobsIDontGetTired
The proposed exhaust setup so far:
- EFR 9174 w/ 1.45 A/R Turbine Housing
- 3" V-Band on Turbine Housing with downturn to 3" to 4" expansion
- 4" Downpipe w/ Bellow
- Dual Turbosmart CompGate 40mm Wastegates w/ Bellows merged back into downpipe roughly 16" after turbine blade
- 4" Downpipe to Dual 3" Oval Y-Pipe
- 3" Oval IN/OUT Mufflers on either side of the underbody of the car. Between the driveshaft tunnel and frame rails.
- Ideal Muffler Dimensions are 3" x 9.5" x 32" for each of the "body" mufflers.
- Dual Oval 3" Over the Rear Axle to Merge into a Third, Center Exit Muffler that dumps as a 4" Oval Downturn.
Should be absolutely bitchin' and relatively quiet, while NOT reducing a bunch of power.

Really guys? Zero support? Zero input? I know the forums are dying, but damn, that's a shame.
The new proposed exhaust system is doing to be dual 3" oval muffler exits into a Y-Pipe single 4" oval that goes over (or under) the axle into the rear muffler which is around 5" x 10.25" x 18".
Sikky Shifter came in. It's incredible. Worth every penny. Bellhousing is cleaned. Clutch Center Hub is getting dropped off tomorrow for Wire EDM to its new input shaft size.
Ohh, and this gem:

No sponsors, no drama, no bullshit. Just badass car design and fabrication.
