PROCEDURE:
1. Locate the round 20-pin diagnostic port in the engine compartment. The port will be in close proximity to the left or right shock tower or
in the vicinity of the intake manifold. The port is covered by a 2
3
/4" diameter, round screw-on cap. Unscrew and remove the cap.
2. To ensure a constant voltage for proper operation of the Power Programmer, attach a high quality battery charger to the vehicle,
capable of a minimum charge rate of 10 amps. Connect the charger directly to the vehicle battery, observing all necessary safety
precautions such as the wearing of safety goggles.
3. Turn charger on to a minimum charge rate of 10 amps and ensure that charging is occurring.
NOTE: The importance of proper battery voltage cannot be emphasized enough; failure to maintain proper voltage throughout the
procedure may result in an inoperable vehicle where the only solution would be the physical replacement of control modules at the
owner’ expense. Please evaluate the age and condition of you BMW’s battery before proceeding.
4. Lower the driver and passenger side windows. Doors should be closed. Engine hood should already be open.
5. Wait a minimum of 15 minutes for the engine to cool and the vehicle battery to charge, assuring ample reserve power.
6. Before using the Power Programmer, clear the buttons by pushing and releasing each button 4 to 6 times.
CAUTION: It is imperative to follow all of the instructions completely and correctly or you may damage your BMW’s
Engine Control Unit (ECU).

IMPORTANT NOTES:
Do not even think about beginning this procedure without reading all of these
instructions first..
The Power Programmer can only function on a stock ECU. If your BMW has a
performance programmed ECU, the Power Programmer will not work.
NOTE: Before obtaining any service on your BMW, restore the stock settings on your ECU. If your dealer/service tech
restores the settings to stock (which they often do) the Power Programmer will no longer work on your BMW.
NOTE: The Power Programmer is designed to work only on BMWs that are US or Canadian spec; it will not work on BMWs
built for Europe, Asia, etc.
