• Rear O2 Sensor Delete - If you are running aftermarket headers please select O2 Sensor delete. We will remove all coding associated with rear O2 sensors 
• Cold Start Delete - All BMW's have a cold start calibration to heat up the catalytic converters. If you're unhappy with the way your BMW idles/runs while cold, select this option and we will adjust the cold start in your tune. Highly advised if you are running a catless exhaust system.
