Pin 13 and 14 (Octane) are for a ignition retard when using fuel with a too low octane number. Well, at least with the standard software.
Mapped software may assign other functions to these pins, like water injection and ALS.

Resistance of the temperature sensors seems to be o.k.
According to this http://bigturbo.co.uk/main4.htm the resistance at 0 degrees is 9750 ohm.
