Hi there,
Firstly, I am guessing the engine is mapped for a decat? I believe the sensor you are pointing at is the O2 sensor which is used by the stock ECU and will probably throw a code if missing, unless its a cat heat warning sensor which might also throw a code if missing. Sorry for not being specific, I have an FC rather than an FC, we just have a single O2 sensor used only in a specific part of the ECU map.
yes been mapped for a decat
i think is a O2 sensor
Im sure someone with an FD will be along in a bit then, not sure how much the FD uses the O2 sensor, they are usually mounted higher up on the downpipe rather than under the car (mine is) I would also look at investing in a wideband O2 sensor to keep an eye on the AFRs if you are getting into tuning it up a bit :)
that is the 02 sensor, you dont need that but under 1 of the seats there is a plug you need to do something with to put the heat light out on the dash, mine is running on twins and i have another wire on the front pipe which is needed
How many wires are on the plug as it looks like a wideband sensor, if it\'s just one wire it will be the standard narrow band, disconnect then use your commander, go into ETC and switch off O2 sensor. It will drive no different.
Do you have a wideband gauge?
The wires Wolfie is talking about is the heat light switch but they would have been joined already for your last pipe.
yes i have a wideband gauge
Then that\'s your wideband sensor, you will need to buy a boss and get it fitted to your new pipe.
Of the top of my head I think it\'s M18x1.5 but you can buy them on eBay.
thanks alot for all you help
