Hi costas thanks for this excellent video. Could you show exactly where you put the rpm probe . Is it between the hall sensor and the ignition module or between the ignition module and sparkswitch ?. Again many thanks for the time and effort you put in to these videos .

Hi Joe... I connected the RPM probe to the Saito's tacho output connector and not the actual sensor. Sensor is connected directly to the ignition box.
So basically it is working off the tacho/rpm connector that the ignition box provides.

Thanks costas. I was having issues like you with my gp 123cc but the rpm probe didn't improve the situation . I was using it between the sensor and the ignition , I will change this and put it in line between the ignition and sparkswitch and see how I get on. Many thanks

Assume the RPM probe has a very high I/P Z?

@@PeterOZ61 I did not check the input impeadance but you are probably correct. It is designed to sit across any hall sensor and then output a pulse to the Sparkswitch.

@@CVHeliPilot would need to have it so it does not load anything down.
