It could be several setting in the tune actually. Hard to tell without more info.
And see my edit in the other post about the MSExtra forums. https://www.msextra.com/forums/
And ask a moderator to consolidate these two posts or you'll be trying to keep up with 2...
I don't believe they were shielded. It looks like standard wire insulation to me. Maybe that is it. Would I should just the signal wire, or all 3 wires (Switched 12v, Signal, and sensor ground)? I have tried the rising edge falling edge setting and it didn't change the sync issue. I will try to get the tune on here tomorrow evening and maybe you can take a look. I will definitely look at the other post on MSExtra. Also, should I be getting power for the crank sensor from any switched 12v, or should it come from the VREF wire that comes from the ECU? Right now it is coming from a standard switched 12V.
