ACT/ECT NTC sensor linearisation - Ford Focus RS Mk.1

Hi - Trying to find sensor linearisation/cal data for the Mk1 Focus RS (Zetec 'Duratec' RS - 4 cyl turbo).

Air charge temp and engine coolant temp? Not sure if they're the same as a regular N/A zetec (suspect at least ACT will be unique due to forced induction/transients).

Any help greatly appreciated, thanks.

Whats the resistance at 20°C? Most manufacturers would stick with one of the commonly available metal oxide compositions and this is what dictates the transfer function.

A part number for the sensor will also assist in providing the information.
