I think Bill is on to something - I looked at my Renesis and it looks like a crank angle sensor (CAS) bracket could be mounted on 3 existing bolts used for the water pump attachment.  I did get an aluminum pulley made for the E-shaft and it could be modified so that another toothed timing wheel could be attached.  The wheel would need to be rotated so that it is off-set from the existing CAS wheel the same degrees as the second CAS is off-set from the existing CAS.  That way no change in electronics would be required to run on either CAS.  The second CAS would be mounted inside the belt orbit.  This would reduce the possibility of  a breaking belt taking out the CAS.

Question - does the CAS wheel need to be magnetic like steel or will aluminum work?  I think it needs to be steel.

Lynn,

 

A toothed belt makes sense. I was thinking ribbed or V.

Bobby,

 

Lynn mentioned this once but it bears repeating, the crank angle sensor is just that. You must be sure that the angle of the toothed wheel and the e-shaft remain in proper timing! Even a very small variance is bad. Your tolerance would have to stay at +- .5 degrees max. That isn't possible with anything but a toothed belt or direct attachment. (which is much better) I had a brain wave one time and thought if people are getting undersized pulleys made, why not raise a flange on both sides and cut the tooth pattern in it? This would be very reliable and would allow 2 pickups for redundancy. The patterns could be cut at the same angle or 180° or whatever angle allowed the easiest mounting of a second pickup.
