I have been asking around on this one and Tom appears to be correct about disconnecting the cam sensor once the computer has "registered" the location at initial start. Timing is done through the crank sensor.
What is not known is the result if the computer looses this registry. This can happen if the battery is disconnected for an extended period of time. The computer will go through an initial start process that sets the timing, injector settings etc. These settings go into a "keep alive" memory that the computer holds after the engine is shut down for the next start.
I am going to be off work for a couple days and I plan to test what happens after the "keep alive" memory is dumped.
