Hello,

I use Defi's additional displays from the BF series with the Link-Meter.

The oil pressure and oil temperature displays are working.

The EGT worries me.

When I connect everything and hold the sensor in my hands and heat it up with a lighter, the display reacts immediately.
As soon as I install the sensor in the manifold, the error occurs (short circuit or sensor not found)
As soon as the sensor has no contact with the vehicle (ground), everything works again.

What exactly is the problem?
