88 BMW M5 VR setup
I am assembling an MSII for an 88 BMW M5. It has two pickups on the flywheel, one for ignition and one for fuel pulse width. It is a 60-2 toothed wheel and I believe it is a VR sensor. My question is, do I wire up the Hall Sensor/Coil circuitry as well, and which setup for it if so? Do I set up with or without triggering off the negative terminal of the coil?

Re: 88 BMW M5 VR setup
If you're controlling fuel and ignition, set it up for a VR sensor and the missing tooth wheel decoder mode. Trigger it off the crank trigger only. It won't hurt to install the Hall effect items if you ever want to switch it to another car, but you won't be using them.
