Re: Trigger wheel mount to space in double pulley

Yah been thinking about this since 2008. I did the simplest setup back then and it worked flawlessly.

The ECU doesn't know where the signal comes from, so as long as it get a 36-1 signal it will work. The VR sensor likewise doesn't care, as long as it "sees" metal pulses. Same sensor is used for both. That reminds me of when Lucas was pioneering electronic ignition back in 1960 for F1, they used flywheel trigger like this but machined in lots of little magnets (if I remember correctly). They had tremendous problems getting the pulse shape correct. VR Sensor puts the magnet in the sensor, so it's much simpler. All you need is a sharp change and a metal tooth width of about 4 mm.

Here are a variety of VR Sensors used with EDIS, they vary by how they mount and where they point. You can also use GM or Chrysler VR sensors and probably a lot of other brands. Notice the Crown Victoria unit mounts in a hole, with a tab to bolt it down.
