For those who enjoy getting the most out of their vehicles, a Racechip is an excellent choice. It allows you to maximise the performance of your vehicle. Essentially, a Racechip is an electric monitor that optimises engine performance, allowing your car to produce more power while using less fuel. It is installed in your engine between the motor controls and the sensors. The monitor is installed by first disconnecting the existing plugs from the engine and connecting them to the monitor instead. Installation takes approximately 15 minutes for most cars and does not necessitate the use of any tools or mechanical expertise. It is completely safe to use a Racechip, and it can make driving a more enjoyable experience.
Part 1 Accessing the Engine
1. If the car has been driven recently, it is recommended that you wait approximately 10 minutes for the engine to cool. The engine becomes extremely hot and will not be safe to touch until that time. In the meantime, please turn off your vehicle. When you’re ready to start the installation, place your hand near the engine to signal that you’re ready. Allow it a little more time to cool down if you notice any heat emanating from it.
The amount of time you have to wait depends on how recently you have driven the car. If you’ve just returned from a long drive, give your car at least 30 minutes to cool down.
2. To gain access to the engine bay, lift the hood. Pulling the hood opening lever from inside your car is a good idea. It is usually found on the driver’s side of the vehicle, below the dashboard and close to the door. Following the removal of the hood, exit the vehicle and secure the doors with your keys. Prop the hood open so that you can get a good look at the engine.
The ability to lock the doors is beneficial in the event that someone accidentally turns on the car while you are working. If you have an electronic engine starter, make sure to place it in a safe location away from the vehicle as well as the car.
3. Remove the clips or bolts that hold the engine cover in place to detach it. In most vehicles, the engine is protected by a sheet of black plastic. Small plastic clips are used to hold it in place most of the time. Locate the clips that run along the top surface of the lid and pull them up to remove them from the lid. If your cover is held together by bolts instead, a 4 mm (0.16 in) socket wrench will suffice.
Depending on the vehicle, removing the cover may be a little more difficult. Due to the fact that the sensors and intake valve are connected to the cover, it is possible that you will need to remove them. More information can be found in the owner’s manual of the vehicle.
Some vehicles are equipped with a cover that does not require any attachments and can be pulled up by hand. Others may not have any sort of protection at all.
Part 2 Connecting to the Turbo Boost Sensor
1. Locate the turbo boost pressure sensor, which is located on the engine’s cylinder head. Look along the back of the engine for a large, black plug that is visible through the exhaust. The plug is typically located near the top right corner of the engine. The plug is also equipped with a round, flexible, black cord.
When you place an order for a Racechip, the manufacturer will inquire as to which car you own. If you provide them with the vehicle’s make and model, they will send you detailed instructions with full-color images showing where the sensor plugs are located. It can be extremely helpful if you are having difficulty locating them on your own.
2. Remove the turbo sensor plug from its connector by pulling it out. Look for a small tab on the top edge of the plug’s plug. Hold the back end of the plug in one hand while pressing the tab down with the other. Then, using your fingers, pull the plug away from the connector. The tab detaches the plug from the connector, allowing it to slide straight off the connector.
Keep the plug in a gentle manner so that the tab does not become damaged. If something appears to be stuck, don’t force it. Make sure the tab is firmly pressed in, and then pull out with firm pressure to release it.
If the plug is not accessible, it is possible that you will need to disconnect some other components first. Sometimes the air filter and intake tube are in the way, for example, and can be removed with a socket wrench to make room for the engine.
3. For gas engines, connect the Racechip plug with the letter A in its centre to the connector. Take the wiring harness for the Racechip out of the box and look for letter markings on the different plugs. An electrical plug and socket will be attached to the end labelled A. Ensure that the plug is aligned with the turbo boost pressure sensor outlet, and then push it in until you hear a snapping sound.
Because the plug can only be installed in one direction, you cannot inadvertently instal it the wrong way. It will not fit if it is not properly aligned with the sensor.
It should be noted that diesel engines operate in a slightly different manner. If you have a diesel vehicle, the plug with the letter B is intended to be installed in the turbo boost pressure sensor.
4. Connect the old turbo boost connector to the Racechip’s socket using the included adapter. Use the socket on the end of the wiring harness labelled A to connect the wires. It’s the one that’s right next to the plug that you inserted into the socket. To complete the installation of the first end of the harness, snap the two pieces together.
Keep an ear out for the snap that indicates that the plug and harness are properly connected. You may not be able to hear it because it is quite loud, which could indicate that the plug is still loose. While holding down the tab, apply a little more pressure to it so that it goes in.
If it doesn’t fit, it’s possible that you’re using the incorrect end of the cable. Check the letter label a second time.
Part 3 Completing the Wire Harness Installation
1. If you have a gas engine, look for the absolute pressure sensor in the manifold. Located on the upper left portion of the engine, close to the passenger side of your vehicle, is this sensor. Even though it’s a little more difficult to locate than the turbo sensor, it’s not impossible. A black plug and cord are also included to connect it to the rest of the vehicle’s electrical system.
Refer to the instructions that came with the Racechip for more information. The manufacturer includes an image that shows you exactly where the sensor is located on your vehicle’s instrument panel.
2. If you have a diesel engine, you must locate the common rail sensor. Every diesel engine is constructed with a metal tube in the centre. When looking down from above, the tube is referred to as the common rail, and it is easy to see because of its colour. One end of the rail will have a round plug on it, which will be the location where the Racechip’s connector is intended to be connected to the rail. If you don’t see the plug at the ends of the rail, it may be in the centre of the rail for some cars. If you don’t see it at the ends of the rail, check the centre.
One method of locating the sensor is to follow the fuel injection line that runs from the fuel tank to the engine’s fuel injection system. A union nut, which is a large, plastic ring that will be located nearby, will secure the rail. The nut makes it simple to remove the sensor’s plug from the sensor.
For more information, refer to the instructions provided by the manufacturer. It will include a photograph illustrating the location of the sensor on your specific vehicle model.
3. By pressing the tab on the plug, you can disconnect it from the sensor. You should be able to find a small tab running the length of the pug. Hold the end of the plug in one hand while keeping one finger on the tab in the other. Then, pull the tab away from the sensor to detach it from the circuit.
The absolute pressure sensor in the manifold of a gas engine is identical to the turbo boost pressure sensor in a diesel engine. You can use one to find the unlocking tab on the other, and vice versa.
4. Insert the remaining Racechip plug into the sensor’s corresponding hole. Take the other end of the wiring harness and connect it to the computer. It will be equipped with a plug and a socket. For the plug to work properly, first align it with the sensor outlet, then push it onto the sensor until you hear it click into place.
You should use the end of the wiring harness marked B if you are working on a gas-powered vehicle. If you’re using a diesel plug, use the one with the letter A on it instead.
In addition, because the plug is made specifically for the sensor, there is no possibility of installing it incorrectly. It may not fit properly if it is not aligned correctly with the sensor outlet.
5. Connect the sensor plug to the electrical outlet on the wiring harness. After you’ve finished connecting the rest of the wiring harness, you’ll be left with one final outlet. Take the old plug that you removed from the sensor and insert it into the harness as described above. It will be a perfect fit when it comes to wiring the Racechip into the vehicle’s computer system.
To avoid overloading the outlet, make sure it’s directly across from where you plugged in your device, rather than one at the other end of the wiring harness. That one is intended for use with the turbo sensor.
At this point, it is recommended that the Racechip be turned off. If it comes on, it means that your vehicle is still running. To reset the Racechip, turn off the car and unplug it from the power source.
Part 4 Installing and Activating the Racechip
1. Take the deactivation plug out of the wiring harness and set it aside. You are now ready to connect the Racechip to the wiring harness using the connectors provided. There is an extra plug in the centre of the wiring harness, but it will be covered by a blocker during installation. Locate the purple clip on the side of the harness and gently pull it away from the body. With the clip removed, you should be able to pull the blocker away from the plug.
If you’re having trouble removing the plug, look for a removal clip or tab on the side of the plug. Check to see that it has been pulled all the way out or that it has been held down.
Keep the deactivation plug in the glove compartment of your car. When it is necessary to deactivate the Racechip, simply reconnect the plug to it.
2. Connect the Racechip to the wiring harness using the jumper wires. Take the Racechip out of the box and align it with the plug on the wiring harness to complete the installation. Take note of the white sticker on the plug, as well as the brand logo on the Racechip, which are both visible here. Make certain that they are all facing the same direction. Afterwards, gently insert the Racechip into the plug until it snaps into place.
The Racechip will not fit unless it is inserted in the proper orientation. Before attempting to instal it, make sure it is properly aligned with the plug.
The Racechip should not be illuminated at this time. If this is the case, you will receive an error message. Remove the Racechip from your car and double-check that it is turned off.
3. Attach the Racechip to the mounting clips and cable ties with cable ties. In addition to four mounting clips and a couple of cable tie loops, the Racechip comes with everything you need to hang it inside your car. The mounting clips should be positioned in the corners of the Racechip and should be snapped into the small openings on the back of the Racechip. Slide a large cable tie through the upper and lower clips on the left side, and then repeat the process on the right side of the clip.
The clips are easily removed. To move the Racechip, pull the clips off of the car rather than removing the cable ties that are holding it in place. After that, you can rehang the Racechip using the old ties.
4. For the Racechip, choose a stable location along the side of the engine bay where it will not be damaged. See if there is a clear space around the edges of the engine bay where you can hang the Racechip. Locate a location where you will be able to use the cable ties. In many cases, vehicles’ frames have exposed metal bars or holes where the cable ties can be passed through to secure the vehicle. Tie the Racechip down with cable ties to ensure that it doesn’t move while you’re driving.
Always keep an eye on the wiring harness when working on a vehicle. Check to see that you will be able to safely route it through the engine bay and that it will not get in the way of any moving components.
5. Use cable ties to keep the wiring harness in the engine bay from moving around. Place the wire harness on top of the connecting cables that run along the back of the engine and see if that helps to stabilise it. It should be connected to the other cables by means of the smaller wire ties that came with the Racechip. After that, inspect the cable to ensure that it is securely fastened and out of the way of the engine components. Then, using wire cutters, cut away any excess length from the ties.
Caution should be exercised to prevent the cable from being stretched too tightly. It could snap if there is too much tension on it.
6. To put the Racechip through its paces, turn on the ignition. Turn the key in the ignition to turn on the car’s lights and radio without turning on the engine. Lights and radio will be turned on as part of the electrical system’s response. Make sure that the Racechip is receiving power as well to ensure that it is working properly. After confirming that everything is functioning as intended, reinstall the engine cover and close the hood. After that, take your car for a spin to see how it handles now that it has the new chip!
If the chip does not appear to be functioning properly, turn off the vehicle and check the plugs. To ensure proper sensor connection, check that the wiring harness is in good working order.
