I am looking for others who may have used the PIP signal for a cam trigger/position. I want to remove the TFI module and go directly to the Hall sensor inside the distributor. It is a 12V signal. I already have a 36-1 wheel on the crank.

Can this be done? What were the results?

I have two different Ford VR sensor. They are both two-wire but the connector is different. I noticed that they have different internal resistance. One is at 385 Ohm the other measures at 625 Ohm. Is the resistance important? Does it affect the signal produced?

The circuit is Ford EEC-V.

And yes the sensor is going in the existing hole on the front timing cover of a GM LS2 V8. GM has a Hall effect sensor in that hole.

The reason for the question is actually quite simple. I am using a Ford VR sensor to detect cam position on a GM V8. GM put holes in the cam gear to reduce weight and inertia. I don't want the edges of the holes to affect the signal. One trigger tooth will be welded on the gear and I'm trying to ...

My question is the reverse of your answer. I am looking at the minimum air gap necessary for the signal to disappear. I know that as I pull the sensor away from the wheel, the signal will get fainter.

I am trying to find out what air gap is needed for the signal from a VR sensor to disappear. I know this may seem like a strange question but I know they are typically installed with 0.03~0.04" gap. Would a 1/4" gap be enough?
