A Quick and Easy Guide to Installing a Performance Chip
Better fuel mileage, enhanced turbo boost, and improved handling and transmission are just some of the benefits of an automotive performance chip. Installing this aftermarket component is one of the most popular car performance upgrades that drivers really like because it's very easy and effective. You can get it done even at your own garage in a matter of 30 minutes. Here are the steps that you should follow:
Required skill level: Intermediate
Tools and materials you'll need:
Preparing the car before the installation
Familiarize yourself with the right instruction procedure of the specific chip you're installing. Don't forget to engage the emergency brake to prevent the car from moving. Before you start, make sure that the negative terminal is off from the battery to avoid being grounded.
Accessing the ECU
You can install a performance chip directly in the dashboard if you will remove the glove compartment. Open the glove box by removing the screws that hold it in place. If the glove box is mounted by tabs, simply pry the tabs with a flat-head screwdriver.
Clipping the chip/chips
Find the ECU box once the glove box is out. Locate the stock chip that you want to replace. Check the vehicle owner's manual to know the exact location of each chip. Remove the old stock chip by unclipping it. Fasten the new chip in place of the old. Make sure that the copper pins are touching the base of the chip slot. When theses pins are loose, the chip might not work properly.
Installing chip to the engine
Some chips such as the fuel injection adjuster chip must be installed to the engine. You have to open the car hood and clip the chip to the specified spot or point on the engine.
Wiring the chip to the ECU
After installing the chip, you have to connect it to the car's main computer or the ECU. Pull the wire from the chip until it reaches the wiring harness at the back of the ECU. Simply attach the black clip at the end of the wire to the car's ECU. Avoid bending or kinking the wire as much as possible.
Testing the chip
Reconnect the negative cable to the car's battery. Insert the key and switch the ignition on but do not start the engine. Leave the key there for three minutes to allow the ECU to adjust the throttle positions. Check for errors and wait if the check engine light turns on; if it doesn't, it means that the installation is successful.
