CAN LAMBDA O2 sensor placement

Recommended Posts

Hi

I was hoping someone could help me out with a suitable location for the O2 sensor placement for my Can Lambda.

I have a 2004 STI with a rotated turbo kit I understand the instructions say

"To avoid excessive heat the sensor should be mounted at least 1 meter from the engine exhaust port."

BUT

Is there an optimal distance from the back of the turbo to put the sensor?

 

Cheers,

 

Scott

No, not really.  The aim is to minimise the sensor exposure to temps >930°C.   Some engines run much higher egt than others, so sometimes it needs to be considered more carefully but usually on road cars somewhere around the 1 meter mark is usually very safe.   Obviously the further away you go, you get a bigger lag so you have to balance that.
