Disabling the G-Sensor...

Also known as the YAW sensor, This sensor was only fitted to generation one Smarts, it won't be found on any cars with ESP (Mk7's).

While turning a corner this sensor monitors the cars sideways force, if you push it to far the ECU will cut the power to avoid loosing traction on a bend.

To disable to sensor you have to jack the front of the car up, drop the under tray and located it (just to the left of the battery box).

There are two screws holding the sensor to the chassis, remove one of the screws and slacken the other, turn the whole sensor 90 degrees and re-tighten the slackened screw.

The sensor will now only be fixed in one place but this does not matter as the sensor has hardly any weight to it.

By spinning this sensor 90 degrees the car thinks its going everywhere sideways, the ECU knows this isn't possible so it ignores the sensor allowing you to go around any corner as fast as you wish.

Please remember that this sensor was installed to these cars for a reason, it wouldn't be wise to do this modification if you are still running standard wheels because of the lack of grip.
