Hi Bill,

I think that will explain why I was having a few issues aswell - is my version affected aswell? 2.1 ?

Also, running one of my engines, and it appears that it doesnt pick up on every revolution (at least not on the external display) - is this normal? i have looked over & over, and the sensor is close enough to the spinner at all times, and manually moving it past the sensor it always picks up... any ideas?
