i purchased the 50% underdrive pulley and it does not have the teeth like the stock crack shaft pulley does [?|] .... there are pins in the new pulley. what i am trying to ask is can the crank shaft sensor sense the pins at the end of the pulley [thumb]

My UDP from Black Diamond doesn't have pins either. What the VR sensor sees is the spot where there is no metal. If you look at the UDP, you'll see little metal rods embedded in the UDP, then a space. The space is what the VR sensor sees and tells the ECU to fire the coil.
Clear as mud, right??
