Its easy a wide band air fuel gauge for the air fuel , SCT is working on the tuning for the 2012 that will also come with a way to check for spark knock

You would think that companys would check to see if there product is running lean wouldnt you , or if they cause any spark knock and some do but there not going to tell you , there selling a part not a part with tuning / datalog service , its your responsibility to chack air fuel and spark knock not the compamy selling intakes , headers , cams , SC , Turbos etc

Thats why I am here now warning I have seen lean 2012 Foci
