I believe with DIS you only need crank signal as the coil packs fire two
plugs at once.  It only has four coil packs so each one fires once every
revolution.  The wheel is on the crank shaff and on the LT-5(ZR-1) its
inside the crankcase but I'm sure I could rig up something to the
vibration damper.  The #1 is found by an 8+1 number of slots in the
ring.  The output to the ecm from the DIS is not altered for this pulse,
>its always 45 degrees on then 45 off (crank).
