    Default Wideband question

    How far away from the turbo does a wideband have to be? the wastegate is gonna be recirculated back into the downpipe about 3-4 inches after the turbo.

    Thanks

    Mine sits about 13" away

    Autometer says "Turbocharged applications should have sensor installed 4-5 after turbo on the down pipe." But mine works just fine at 13"

    Mine is further down as well. It went in where I had a bung available to use.

    I've placed the af sensor 10-18" with best results closer to 10". Mostly depends on temperatures and how much unspent fuel it'll see.

    Mine are about 12" from the turbine side. RE-working everything with this new motor and going to move them closer as i had some weird variances looking at eh logs form bank to bank and I'm wondering if it was due to placement as i had them in the radius of a bend. Keep them between 10 to 2 oclock in the pipe so moisture doesn't mess them up.


    I think where most of you have your problems with all of this, is the fact that you really don't fully understand the internal workings and dynamics of the common combustion engine. There is no magic tune up, and motors are stupid. The only time a motor will complain is when something is wrong.
