berg Posted April 29, 2015 Share Posted April 29, 2015 Can anyone confirm the correct place to have a wideband sensor installed on my exhaust Currently BPU with 1st and 2nd decats Heard mixed stories regarding how far away from turbos, not sure whether to install in 2nd pipe or 1st Its an AEM UEGO if that makes any difference Link to comment Share on other sites More sharing options...
David P Posted April 29, 2015 Share Posted April 29, 2015 The destructions that came with it should say "at least 1m after turbo(s)". At the bend in the 2nd decat pipe fits the bill and there is a convenient hole to route the cable inside. Link to comment Share on other sites More sharing options...
berg Posted April 29, 2015 Author Share Posted April 29, 2015 Thanks ill get that sorted today saves having to take the first decat off which is good news Link to comment Share on other sites More sharing options...
David P Posted April 29, 2015 Share Posted April 29, 2015 Mount it above the pipe centreline so that water drains out of it and not into it. Link to comment Share on other sites More sharing options...

j_jza80 Posted April 29, 2015 Share Posted April 29, 2015 Here's the instructions for the Stack Wideband/AFR gauge I've just fitted. It clearly says; Turbocharged applications should have sensor installed 4-5" after turbo on the down pipe So mine is fitted to my first decat pipe.

Chris Wilson Posted April 29, 2015 Share Posted April 29, 2015 I always fit wide bands near the turbo outlet, they react faster there. Never had issues with Bosch sensors, some installs have had them within less than 4 inches. I have seen manufacturers test engines with wide bands within a couple of inches of each head port, where EGT's will be almost as high as those in the cylinders. After a turbo things are a lot cooler. Link to comment Share on other sites More sharing options...
