KPro 4 Oil Pressure Issue

[MattCherrington]

Hi all,

I've installed an Autometer 2246 Oil Pressure Sensor into a K20 with a Kpro4.
As far as I can tell, everything is wired correctly, and when running the engine, I can measure a difference in voltage across Analog 0 and the ground pins as the engine is revved, so there is a change in measurement occurring with oil pressure.
However, I can not get this to display on the sensors page in Kpro.
The car has an Aim PDM and dash. All other ECU parameters such as water temp, throttle position, battery voltage etc are coming through fine, but oil pressure is fixed at -4.3psi.

I've tried using a custom sensor in the calibration as well as the Autometer preset, changed units from bar to psi and back again, but nothing seems to make a difference.

Calibration and log file attached.

What am I missing? Im sure its something simple!

Thanks.

How exactly do you have this wired?

As per instructions I think.
Taken a 5v reference from the throttle position sensor, AN0 (red) to purple signal wire and earth to both the GND pins of the connector with the analog inputs.
