Well I needed to check and adjust this rotten little unit again today after an engine rebuild and wasted some more time. As far as I'm concerned, the only way to quickly and accurately get this right is to adjust the IP dynamically. After noticing how close the other internal lobes are in relation to the desired reference tit leads me to believe that an inductive pickup may not be ideal.

Any thoughts on the accuracy and availability of common electronic pickups whether they be pulse sensors or hall effect devices? I would be willing to bet that a standard knock sensor signal could be amplified. At the same time a dummy actuator placed in the IP delivery tube might be easier and more accurate although it might mean running the car on 5 cylinders for the adjustment.

I swear I'll come up with an inexpensive and accurate solution then post the schematic. I never did like static timing except on lawnmowers.
