i would imagine Don would be using megasquirt. i doubt the s38 intake / airbox would fit with the brake booster - i could be wrong. perhaps Don can share what is successful.

Paging @nosmonkey ; you're running an S38 isn't it? Didn't you have a s*xy carbon fibre airbox?
there are a couple companies that make a DCOE ITB:

M88 with a carbon plenum, although being rhd i have more space on the intake side.
Personally on an m30/m90 would either go jenvey heritage dcoe itbs with an appropriate manifold or the kit from rhd engineering

There are adapter plates available for adopting the S38 ITBs to the M30. But I would not go this route as i) the S38/M88 ITBs are ported for the intakes with two valves and ii) such solution will be more expensive than using kits specifically designed for the M30. Additional suppliers for M30 ITBs are Dbilas and VGS.
For MS'ing M30s with Motronic, there are P'n'P solutions available like the KdFI, it is a bit harder to transition L- or D-Jet engines.

My goal here is to use the DCOE carbs with the M90 motor, not to transplant an M90 CSi engine into the car. Looking at the Karsundpartz (Pierce. Ireland, etc) manifold I see that it is formed to the shape of the B30 intake ports, so I’ll either need to port the manifold to the head, or make a new manifold. I think I can port the ones I have unless the flanges are too small
So, I'm curious about this setup (not because I plan to use it, but just engineering curiosity). With these ITB systems, how does the ECU determine mass air flow? Are there multiple MAFs?M88 with a carbon plenum, although being rhd i have more space on the intake side.

Usually, the corresponding ECUs on modified engines work with MAP sensors and/or alpha-N models. The standard M88 and S38 has a Bosch MAF, however, as more proper for daily street use.
The nice thing when using a programmable ECU like Megasquirt on a Motronic/L-Jet M30/M90 , e.g., is that you can get rid of the old flap based AFM which is restrictive on modified engines.

Is Halltech also an option for you?
I have two S14 friends (both engineers) that converted to the Halltech system with the "throttle by wire". They are extremely pleased. I can provide their contact if you want to speak to someone.
