Installing an Aftermarket Performance Chip
Last Updated: February 05, 2005

Aftermarket chips have become taboo as of late, but the right one will help your car in many different ways. This is a small write up on installing your new chip. I completed this mod in my driveway in less than 30 minutes.

Tools Needed: 7mm socket, ratchet, 4mm socket, small hex head bit, and screw driver with interchangable bits.

Step 1: First start off by removing your glove box, it is held in by 4 small hex head screws. After this move to the lower dash cover. This is held in with 4 7mm screws and 2 studs going into the firewall which can be removed using the 4mm socket. Now you should have a clear view of your computer, it is located on the right side of the car in front of the door and above the kick panel.

Step 2: Now you will need to take the computer out of its holding area, there are some small clips that can be unclipped by hand, unclip these, now lift the computer upwards and then pull the bottom out. With some wiggling it should pull free. Next you will need to unplug the 3 wiring harnesses out of the back of the computer(no real need to take note of which goes where, they only plug in 1 way). Now the computer is free to leave the car.

Step 3: With the computer out of the car and in an easy working spot you will need to remove the small cover on the side opposite of the wiring harness plugs. This is the small cover that is on top of the rest of the computer. I couldn't find the appropriate socket so I used a crescent wrench to remove these. With this cover off you will see the stock chip plugged into the computer. Now you will need to unclip the stock chip, this is pretty self explanatory once you are in there. Now with your aftermarket chip just put it where the stock chip was. Push it down and clip it in to place. After you have done this you can place the cover back on and begin the reinstallation.

Like I previously stated the right chip can help your car a lot, you should take the time to look into a good chip to make it worth your time and money to buy the chip and install it. Check out our links section for good chip choices. BerettaSpeed recommends the chip produced by Ben Phelps of
