For refference I own a 2012 MCS, and I have seen a few comments saying that the R56 comes from the factory with a wideband O2 sensor. I am considering my gauge options, and if instead of a new wideband unit I could use an OBDII gauge, this may change the setup I choose. Just wanted to check and make sure what type of sensor is used before I start buying things. Thanks!

 

Head over to the Modifications section and you can find out a lot more info on this stuff as this stuff is common to ALL 2nd Gen cars not just the R56
