I don't know if the speed sensor will work there with the rf that the engines put out but its just a passing thought maybe one of you guys might want to give it a shot?
I suggested that in post #5. The sensor (reed sw) works but unfortunately range of calibration on my unit did not allow useable RPM readings.
