Ok we live in a very very nice area, I ALWAYS leave my garage open, well none the less my tuner was sitting on my work bench on some punk the other day felt the need to swipe it from my garage. So Today I had to bite the bullet and buy a DiabloSport tuner, not too bad I have a C&L racer setup anyway.. my question is this..HOW can you turn off your rear O2 sensors or your front ones .....?? THis thing is alot differnt from my X3 so anyhelp guys would be awesome.. ALSO this unit didnt come with intructions ..anyone have a PDF version of it !?
