Selling my BMW Accessport by Cobb. This can be used to modify factory fuel map settings to unlock more horsepower and torque from your N55 3.0L engine. It can also read and reset check engine codes. This is a software only solution, no wiring required. I’ve used this without any issues in my car for serval years and it makes a significant difference in how aggressively the car performs. It’s very easy to use and quick to install/modify/uninstall. This unit was properly uninstalled last week and is ready to pair up with a new car!
