Title: 02 sensor extensions for De cat exhaust.
Post by: GTI 500 on October 28, 2021, 11:08:06 am

Anyone used the 02 sensor extensions that are supposed to stop the EML coming on after fitting a De cat downpipe??

If you use one, make sure it goes on the secondary O2 under the car, not the one next to the turbo.

Most remappers disable the secondary O2 in the ECU software.  What map do you have?

Not had it mapped yet, but will be mapped next year just wanted to fit the down pipe to see how it performed/sounded but dont want the EML on.

In that case you'll be wanting something like this, but ebay is half the price - https://www.awesomegti.com/shop-by-car/volkswagen/golf-mk4/cts-cel-eliminator-o2-sensor-spacer/
