Wideband Lambda Location in exhaust

(1/2) > >>

Sprocket:
Where is the best location for the Wideband Lambda to be located. I have heard that they do not like extreme temperatures above the 800c mark. Thats not too much of an issue as the turbo I am using has a max of around that any way and i will be obviously monitoring the situation with the EGT. Will it reac that temp you ask, well possibly, I intend to use ALS on odd occasions for drag days, the boost will be 15 psi at the max with 9:1 cr so the EGT will be high to start.

Just dont want to burn out these little puppies as they aint cheep to start.

Location options - befor the turbo, imediately after the turbo or in the down pipe some what after the turbo?

rob@vems.co.uk:
The lambda is best after the turbo somewhere in the downpipe that allows the sensor to sit as close to verticle as possible.

Verticle as possible... why?

Sprocket:
Well, if i stick it in the down pipe, it will have to be horizontal, though it will be in a vertical length of exhaust.


I think the 'as vertical as possible' it to prevent water gathering in the sensor tip???

rob@vems.co.uk:
Correct, its to stop water issues.
