How to Switch Maps

Insert the keyfob and press the start button to turn the ignition on (lights on the dash but the engine is not running). Press and hold the gas pedal down to the floor for 4 seconds or more, then release. This puts the Power Box into listen mode. If you start the engine at this point you will be on map 0. For performance maps press the gas pedal to the floor and quickly release one time for each map you would like to select. For example, for map 3 press and release the gas 3 times, then start the engine. Your map setting will be saved until it is changed.

No, it is all installed under the ECU cover. Check out the link I added and you'll see how it is installed.

If you open your white ECU box you can look to see if the power box unit is inside. If you've never crept around under the E9X hood before it'll probably take you 20-30 mins to get there. There will be install instructions on the BMS website to access it.
