which lambda for spacer?

[elviscat]

Hi all,

Quick question, am fitting lambda spacer as have bank 1 engine management light on after pipe fitted with 200cell sport cat and wondered is it front or rear lambda for the spacer.

I think it's rear but would like confirmation?

Thanks a million

Its the rear, thats the one that works after cat.

^ yup as gravesie said. The rear one is used to check the condition of the cat whereas the front one is used for fuel adjustment.
