I'm just about to start my annual major service and inspection on my '02 Boxster S.
Before starting, I plugged in my trusty Durametric (what a great tool that is) to check for error codes (non found) and going through the menue I checked a few parameters like fan operation, voltages, etc.
I also checked an item called "Camshaft Position 1 Deviation" and "Camshaft Position 2 Deviation". When checking these (obviously with the engine running @ 800rpm) I got:

Camshaft Position 1 Deviation = -5.26 *Crk.
Camshaft Position 2 Deviation = 0 *Crk.

Anyone know what Camshaft Deviation & these numbers mean?
Do I have to worry??

I THINK its the cams retarded @ idle revs before the Variocam kicks in, but......
