I was just wanting to know if you could turn the rear o2 sensors off using the x3 sct tuner? I bought some bbk MIL Eliminators but they are not working. I hooked them up and reset the ecu by unplugging the battery but the stupid sevice engine soon light is still on. So I am going to be getting 4.10's soon and the tuner and I was just wondering. I can't stand that light being on! thanks guys
