67 twin turbo dart

It’s worth a shot. From what I’ve learned, that sensor has a small strip of the face (as opposed to the entire face) that is actually the sensor. Given your thin reluctor wheel and the little strip of sensor it’s easy to see how it could lose signal. I have a 36-1 wheel just like yours and I opted to not use it and went to the wide face AR Engineering wheel.
Yeah thats why I'm leaning more toward a better sensor that has the full sensor over the small strip.
