Crankshaft position sensors for 5L AJ133 V8s from 2009 through 2015 are inductive sensors. Crankshaft position sensors for AJ126 V6 and AJ133 V8 from 2016 are Hall Effect sensors.
The reluctor ring for the inductive sensor is stamped steel but the ring for the Hall Effect sensor is a bit more massive cast/machined steel.
Output voltage from the inductive sensor varies with speed: less than a volt at idle to 100 volts or so at higher RPM.
Output voltage from the Hall Effect sensor remains fairly constant at approximately five volts.
Should a late model V8 be fitted to an earlier model (2009-15) JLR vehicle, it would seem that the Hall effect sensor could be used, assuming power to the Hall Effect sensor was provided.
Yes, changing to the older flex-plate/flywheel and retaining the inductive sensor is possible, but what if ... ?

A related item, the location of the sensor is fixed, and thus the mechanical adjustment to sensor timing. The ECM advances timing in accordance with RPM and other parameters. Is there a relatively simple way to electronically change the sensor timing approximately 18 degrees?

Your constructive thoughts and encouragement will be greatly appreciated.
