This is the future!
What we need is a blue-tooth data collection device. It would take the following:
- Airspeed
- Altimeter
- Tachometer
- Oil Pressure
- Oil Temperature
- Manifold Pressure
- Amp Meter
- Fuel Pressure
- Fuel Flow
- Fuel Level x3
- EGT x4
- CHT x4
That's 18 channels (16 analog, 2 digital). Teensy 3.1 can support this.
Then need to find an open-source EFIS... If only such a thing exists...
