I don't know of anyone that's done it but from what I know of megasquirt you can run just about anything off of it.

Check the megasquirt forums.

Yup I just got my Fuji Racing IRTB's running this weekend.

It runs pretty good and so far but I haven't made it to the dyno yet.

You pretty much have to run Alpha-N or Hybrid Alpha-N. The Map signal goes straight to 100 with the slightest throttle input, so Speed Density probably wont work well.

The Squirt has everything you need to run your IRTB setup.

I'm using MS-II with ITBs, but on a 20v 4age in my Corolla. Currently using hybrid Alpha-N, works great but takes some tuning. Later versions of the code will allow the ECU to switch from Alpha-N to Speed Density at a certain MAP as well as RPM, for boosted cars (right now it only uses an RPM threshold).

And WTF is the R in 'IRTBs'??

Its a Miata thing. They were ITB's to me before I bought a Miata

Or you could box in the trumpets to get a reliable MAP reading.

At which point the MAP reading is useless, you need to measure the pressure after the throttle plate(s).
