Either cut and shut or hybrid, same sort of thing in my eyes mate.
The phase sensor is a shite component that always causes problems after X amount of time. Becuase it is in the dizzy it suffers from loads of problems related.
Apart from all that it is not needed and is another moving part in the engine bay which does not need to be there.
I could go on but its "pointless"
A cam sensor is just a magnetic trigger. Nothing to fail or wear.. Obviously one day you will need to change the sensor, but i know of 15year old Cosworths with the same CPS from the factory with no problems or change in Ohms. Reliablity is the second most important. First it needs to work...
