3 o2 sensor inputs? Any provisions for closed loop modes with variable AFR targeting?
Will there be AFR logging directly onto the 3d fuel map?
Looks pretty cool

Since I know Robert is at Reno, I'll answer what I do know..
The port mount injectors are an option, yes. Robert has always maintained that the intake mount is preferred. The port mount does make it a lot easier in a retro fit situation.
I doubt there will ever be a closed loop situation with regards to AFR, you can ask Robert about his thoughts on that.
Yes, all engine info will be logged into the system and recorded...
If your at Reno, swing by Robert's booth to see the new stuff and ask as many questions as possible.

Huh?
Measured inflight air temperatures ballpark at OAT plus 15 to 20F for the top side.
Bottom side air temp is typically 120F to 220F measured at the cowl exit, depending on heat transfer efficiency. I've measured air temperature as high as 254F at the cylinder wrap exit inboard of the CHT probe on an angle valve head.
Hard to believe a primer port location is on the "cool side".

Methinks Charlie might have confused the primer ports with the injector ports.

The display of the new EFII System 32 at Reno had what they refer to as "Port Mount Injector System" or "PMI". These electronic injectors (not Bosch) were fitted in the primer ports of cylinder heads on display.
An illustration can be seen by clicking this link http://www.flyefii.com/system-32/ and scrolling to the last page. Look for the picture of the cylinder head with EFII valve covers labled, "Port Mounted Injector System" (PMI) to see what I'm referring to.
They still offer the option to place the electronic injectors in the intake tubes.
I picked up a nifty sales brochure on the new EFII product but seem to have misplaced it.

No worries. I forgot what kind of injectors they said they use.
Great seeing you at Reno Mike! Looks like the Rookie Mark Fredrickson #31 "Tenacity" out of Cameron Park won his class. Congratulations! I know you put work in on that!

I have been running my SDS injectors in the primer port for the last 75 hours on my parallel valve 360. I can't compare to other positions, but it has worked so far.
