Does anybody know what the RX-8 throttle body pin-outs are and the
  voltages that the sensor/s needs ?
  We are assuming there is a hall sensor in there somewhere being "Denso"
 it
  appears they have done it
  the hard way. We can simply want to use the throttle body as it is out of
  the box rather than modify it to a cable

 I think Tracy Crook is usng the RX8 TB un his RV8 on a 20B. He seems to
 have
 all the details.
 FWIW.

 Looks like it takes a computer to control it. It looks like
 a closed loop servo system with data fed back from the throttle
 position sensor. It is spring loaded to close to 5 degrees if
 the electronics fail.

 BTW how's your one rotor engine coming Richard. There appears to be a
 fair size market out there.

Still fabricating parts. The most complicated are done(picture). Now I am
doing v-belt pullies, oil pan and PSRU mount. It all looks like what I had
on the first engine, however, the parts now are independent reproducible and
will fit. A couple months more and the airplane installation should start.

Nice part Richard.
