FYI - we haven't characterized the engine and do not know what it would take to run a full compliment of sensors on a Corvair engine. However, the types of sensors that we sell, along with their connection types, are listed on our price list.
Also, know that to measure RPM, our EMS products need voltage pulses that are greater than 10V, and fuel quantity needs to be either resistive (standard floats) or a probe that outputs 0-5V (the capacitive probes from Princeton Electronics are of this type).
