The primary purpose of a performance chip is to optimize your engine’s performance. By adjusting the car’s internal computer, these chips change the engine’s default settings to improve power and torque output, fuel economy, and throttle response.

Chip tuning with RaceChip Pro will make your Ford Fiesta ST more responsive, increasing acceleration and reducing throttle lag, especially in sport mode. It also promotes better fuel efficiency, meaning you’ll get more miles out of each tank.

Step 2: Preparing Your Vehicle for Installation

Proper preparation is key to a successful installation. Start by ensuring your Ford Fiesta ST is well-maintained, with no underlying mechanical issues. Any existing problems could be amplified by the tuning chip, so it’s crucial to address these beforehand.

Next, familiarize yourself with the car’s engine and its components. The performance chip will typically be installed near the engine control unit (ECU).

Ensure the engine is cool before starting the installation process, which means avoiding installation immediately after driving.

Step 3: Installing the RaceChip Performance Chip

Now, let’s get down to the actual process of installing the performance chip. The RaceChip comes with a set of instructions, but we’ll outline the critical steps here.

First, locate the ECU in your Ford Fiesta ST’s engine bay. Connect the supplied wiring harness to the RaceChip unit. Now, find the factory sensor your RaceChip will connect to. This could be the manifold pressure sensor, air mass meter, or fuel pressure sensor. Attach the supplied connectors to this sensor.

After connecting everything, secure the RaceChip unit to a non-moving part of your vehicle using the supplied zip ties. Ensure it’s away from hot or moving parts of the engine.

Step 4: Configuring Your RaceChip

Once the installation is complete, the next step is setting up the performance chip. Using the RaceChip App, you can easily control and adjust the chip’s settings.

The app offers several modes, including Efficiency, Sport, and Race, each providing a different balance of power and fuel efficiency. You can simply switch between these modes using the app, tailoring your car’s performance to your driving needs.

The pedalbox feature in the app allows you to adjust the throttle response. A lower setting will give a more relaxed drive, while a higher setting will provide a sportier feel.

Step 5: Testing and Adjusting the Performance Chip

After setting up the chip, it’s time to test drive your Ford Fiesta ST. Start with a gentle drive to ensure everything is running smoothly. Pay attention to how the car feels, especially the throttle response.

If you’re not satisfied with the performance, you can make adjustments using the RaceChip App. You can continue to tweak the settings until you find the perfect balance of power, fuel consumption, and throttle response.

Remember, installing a performance chip is an investment in your car’s performance. Not only will it make your driving experience more enjoyable, but it can also improve your vehicle’s fuel efficiency. The process might seem technical, but with the right tools and this guide, you’ll be able to unleash the full potential of your Ford Fiesta ST. Happy driving!

Step 6: Understanding the Features of the RaceChip App

Without a doubt, one of the most significant advantages of the RaceChip performance chip is the accompanying RaceChip App. This app is designed to work in tandem with the performance chip, offering customizable tuning mappings and an intuitive user interface.

The RaceChip App allows you to switch between different performance levels, from efficiency to sport to racing, all at the touch of a button. This user-friendly app provides you with a wide range of settings to fine-tune your Ford Fiesta ST’s engine performance according to your driving style and preferences.

Another brilliant aspect of the RaceChip App is the Pedalbox Pro feature. This option lets you adjust the throttle response of your car to your liking. If you prefer a smoother, more relaxed driving experience, you can opt for a lower setting. On the other hand, if you crave a sportier feel with immediate throttle response, the higher setting is right up your alley.

In addition to these benefits, the RaceChip App also assists in managing fuel consumption. By changing general settings, you can drive more fuel efficiently, thereby saving on fuel costs in the long run. The app’s gear-changing advice even suggests the optimal time to shift to a higher gear for maximum fuel efficiency.

Step 7: Protecting your Engine Warranty with RaceChip

One common concern about installing performance chips is the potential impact on the vehicle’s warranty. RaceChip, however, has you covered on this front. With a 2-year product warranty on the RaceChip XLR, you can install and use the performance chip with peace of mind.

The majority of car manufacturers cannot void your engine warranty merely because you have installed a performance chip. The RaceChip is designed to work within the safe parameters of your car’s engine, avoiding any damage. In fact, when you remove the RaceChip, no permanent changes are left on your vehicle, and it reverts to its factory settings. Therefore, it does not pose any risk to the engine warranty of your Ford Fiesta ST.

Nevertheless, it is always recommended to check the specific warranty terms of your vehicle manufacturer before installation. If you are concerned about voiding your warranty, you can always switch off the chip before taking your car for a service.


To conclude, installing a RaceChip performance chip in your Ford Fiesta ST can significantly enhance your driving experience. It offers a more responsive throttle, improved fuel consumption, and the ability to fine-tune your vehicle’s performance to your liking – all controlled through the user-friendly RaceChip App.

While the installation process may seem intimidating, this guide should put you at ease. It walks you through every step, from understanding the benefits of performance chips to installing and adjusting the chip, and even protecting your engine warranty.
