Hi,
Not at all. It could be construed that Porsche is inferior. It's not the OČ Sensors, but the software limits of the DME. It does not have any Maps for the readings the sensor is sending it - the values lie
outside the defined operating parameters.
Your other cars may well be affected, just not to the same degree. The ECU has an adequate Map to cope with the circumstances and so doesn't foul the OČ sensor or send a code...
Happy Motoring!... Jim'99
