Can I put an AFR/wideband sensor here...?

[Johnc172]

On the turbo down pipe? Or is that just for an EGT sensor?

 

[mi16chris]

Yes u might want to put it abit further down tho

Whys that? Heat or to get a more accurate reading?

I'm new to boost!

Yeah, megane 225's have their lambdas next to the turbo.

 

[Dan519]

I wouldn't put it that close, it will get cooked. There's usually guideline from the wideband manufacturer on how far to mount after a turbo. I'd want to be a couple of foot downstream most of the time

different type of sensor, there's a few different ones for different applications

 

[Dan@SJM]

The Vag stuff mounts it about 4" from the turbo outlet.

Cant imagine the gases will cool much if you move it down stream by a few 100mm's. The only thing would be the sensor if further away externally from the turbo but a decent bit of heat shielding would sort that.

 

[Cupman29]

Double post!

 

[Dan519]

put it this way, if you mount it close, you might get away with it, it you mount it further away, it will definitely be safer

 

[Ashburner]

If you put it there the sensor will last about a week before it packs up.

Iv had a MR2 turbo with lc1 wideband on and mx5 turbo in past with a AEM wideband. both recommend its mounted as far away from the turbo as possible.

My wideband is installed in the same place on the downpipe. No issues to report...

 

[Ph1 Tom]

On my zetec turbo it was about 3-4" from the turbo. No problems.

 

[Johnc172]

Hmmm mixed results in here! I've got a gen90 so I'm guessing I could just replace one of the lambda sensor further down? As I'm assuming the lambda is no longer used? I will confirm that beforehand though

 

[Laine_16v]

Yeah you can do that, the GEN90 only uses 1 lambda sensor.

 

[Jaff.]

Bosch ones state 18" away from a turbo charger FYI

 

[Laine_16v]

Mine is 2 inches away lol

 

[Rob_Kipper]

Killed my AEM one in 5 months putting it next to turbo.

Says 36" in the manual.

If you find heat an issue just use a heatsink bung extender.

 

[Johnc172]

Yeah you can do that, the GEN90 only uses 1 lambda sensor.

Do you know which one by the way? One before or after the cat?

 

[Chip-mk1]

Do you know which one by the way? One before or after the cat?

If running a single lambda its always before the cat.
