How to Increase BMW Horsepower
1. Purchase a free-flow air filter for your BMW model from a local or online aftermarket retailer. Locate the air filter case under the hood. The air filter case is usually a black plastic box that sits closer the windshield of the car.
2. Unclamp the lid and open it. Lift the current air filter out of the case and toss in the trash. Clean the inside of the box with a damp cloth or paper shop towel. Input the new filter and clamp the lid shut.
3. Purchase a new digitized motor electronic (DME) computer system chip. Disconnect the battery. Locate the DME compartment on the right side wall inside your BMW engine compartment. Gently snap out the rubber brads and peel back the foam casing surrounding the hard case protecting the computer system. Unscrew the four case screws that pin the hard case closed.
4. Pull out the DME box. Disconnect the tether and two clamps holding it in place. Unscrew the four screws on the box to open. Put on your static wrist strap. Carefully pop off the white case that is on the circuit board. Note the direction that the small divot faces on the DME chip. Gently pry the DME performance chip off of the circuit board with a flat head screwdriver.
5. Snap new performance chip into place. Replace the white plastic cover, the circuit board cover and screws. Reattach the DME to its tether and clips and reinsert in the BMW compartment where it belongs. Screw the compartment closed and recover with the BMW casing.
