Grand Rapids Technologies EIS engine instrument system for Rotax 912
From a recently parted-out 1999 Zenair. This was the model for the Rotax 912 at the time (EIS-3-Adv-W/912).
$800 Canadian.
Measures: tach, 2 EGT, 2 CHT, oil pressure, oil temperature, coolant temperature, bus voltage, fuel flow (& totalizer), fuel pressure.
Sensors like the EGT, CHT will be included. Not including the previously sold Flowscan fuel flow meter or parts that stay on the engine like the oil pressure sensor.

Yes I will sell the EIS separate from the engine. Plenty of 912's out there to match it with!
I did want to sell the sensors / probes with the EIS; and they are included in the price.The sensors / probes: That's mainly the two EGT probes with their special wires, plus two CHT ring terminals (to fit under cap screws that go on the 912 cylinder heads.)
Have a VDO coolant temp sensor and a custom bought in-line hose fitting it works with.
Other wire ends I might not have, as they are for example just female spade terminals. (Like the fitting that goes to the oil pressure sender that is built onto a Rotax 912.)
I should also have a VDO sensor that was used for fuel pressure. (Technically the Auxilliary input on the EIS, could be used for different purposes and programmed to different display values vs. input voltage. But I used it for fuel pressure.)
The FloScan is the fuel flow rate sensor; that I don't have as it got sold separately. (Not everyone uses the fuel flow rate input for the EIS, so the sensor was a separate purchase when I got the EIS.)
That should cover most of the inputs!
