I finished wiring up a 5.9 magnum.
the distributor is a little different than stock. it has a shutter wheel in it instead of whatever is normally in a magnum distributor.


based on the wiring diagram diy auto tune supplied, I wired it in with all 3 wires.
common 5 volt, and then specific ground and sensing line on their shielded wire.

I can see voltage changes in the sensing line. but the tuner studio software doesn't seem to see anything.
I have a resistor wired in to the sensing line as well from how it was previously used.

sent them an email since there is no way to call, but wondering if anyone has any ideas on what to check.
