• Burble - Emits flame and backfire when lifting off throttle. Only suggested for catless exhaust systems.
• 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.
• Flex Fuel capabilities - (REQUIRES ECA KIT) No longer do you have to calculate how much E85 you have to put in your car, or reflash when changing fuels! Just fill it up and the ECU will auto adjust to run based off of the ethanol content inside your gas tank.
• Map Switching - Add multiple maps to your ECU, and use the BC button to switch on the fly! Perfect for if you are changing fuels, or want different burble settings saved.
