Megajolt not showing RPMs

Post by Jadewombat » Fri Aug 10, 2018 4:07 pm

I'm setting up MJ on an 82 vanagon with EDIS4. im not getting any RPMs showing up in MJ lite configurator software. I tried moving the VR sensor several times but it still stays at 0 rpms. checked all the connections and i tried looking at pip signal at the mj with an analog voltmeter. It looks like it's picking up a signal, but is the voltage too low for pip? ~5Volts:

Also, i'm using a small tooth trigger wheel. It's OK to use this from the side like this?

I have spark at the coil pack in limp home mode, etc. Thanks

Nevermind, I figured it out. I spun the trigger wheel on my drill and it shows RPMs. The pickup can ONLY be on the edge, not the flat side of the trigger wheel.

I'm no expert at all but I suspect if your wheel has square teeth, the VR sensor would have worked as originally mounted.
