Custom reluctor ring, suggestions on where to get one

KitCarlson said
I think you completely missed my point. Yes the edges are important, we agree on that. What happens is that the sensor does not trigger at the center of the sensor, but before, and it releases past center.
It is not fractions of a degree, but it is few to several degrees.

This is a Hall Effect sensor, I thought those were pretty much instantaneous?

So what you are saying is that it's the distance past the edges that is the issue, and the diameter of the wheel won't change that distance, even though the number of degrees it rotates will change to get the distance.

Starting point in your case is knowing the precise OEM signals.

Here is what I got from a Mopar engineer years ago in this regards:

"The good news is that it's much simpler than you are thinking. The JTEC is counting on/off pulses. It doesn't care about the width. If you carve 8 equally spaced notches in the pulley/tone ring, then the JTEC will be happy.
Try and line up your new crank trigger to a notch the same time the OEM crank trigger is on a notch. You should have good luck. You will need to adjust the timing by trial and error, but a trip to the drag strip will find the best setting."
