Choosing the Right RaceChip Product

The first step in enhancing your Fiat 500 Abarth’s throttle response is to select the appropriate RaceChip product. RaceChip offers a range of tuning products, each designed to suit different driving needs and requirements. It’s vital to identify the product that will best match your vehicle’s specifications and your performance expectations.

The RaceChip GTS Black, for example, is designed for high-performance cars and comes with a comprehensive app control. This product offers a substantial power increase, making your throttle more responsive.

Similarly, the RaceChip S is a more basic model that still offers a noticeable power increase without the app control feature. It suits drivers looking for a simple yet effective tuning solution.

Installing the RaceChip Tuning Product

Once you’ve selected the right RaceChip product for your Fiat 500 Abarth, the next step is the installation. The process involves attaching the RaceChip tuning box to your car’s engine control unit (ECU). It’s a straightforward task that you can do with some basic mechanical knowledge and tools.

First, you have to locate the ECU in your vehicle. For the Fiat 500 Abarth, the ECU is typically found in the engine compartment. Once you’ve found the ECU, you will connect the RaceChip tuning box using the included wiring harness.

The tuning box comes with several different connectors that match the various sensors in your engine. You’ll need to identify the correct connector for each sensor and plug it into the corresponding socket in the tuning box.

Controlling Car Performance with the RaceChip App

Once the installation is done, you’re ready to control your car’s performance using the RaceChip app. This app allows you to select different tuning programs for your vehicle depending on your driving needs.

The app offers several performance modes. These include the ‘Efficiency’ mode for fuel-saving drive, ‘Sport’ mode for a balance between power and efficiency, and ‘Race’ mode for maximum power output.

In addition to selecting the performance mode, you can also adjust the throttle response using the app’s pedal box feature. This function allows you to control the responsiveness of the accelerator pedal, making it more sensitive for a quicker response or less sensitive for a smoother drive.

Monitoring and Adjusting Vehicle Performance

Another crucial aspect of ECU remapping with RaceChip is monitoring and adjusting your vehicle’s performance. The RaceChip app provides a range of performance data, including real-time engine parameters, to help you monitor your car’s performance.

You can view data on your engine’s power output, fuel consumption, and more. This data can be incredibly useful in identifying any potential issues with your vehicle’s performance and making necessary adjustments.

By regularly checking this data and fine-tuning your vehicle’s settings through the RaceChip app, you can ensure that your Fiat 500 Abarth is always performing at its best.

Remember, ECU remapping with RaceChip is not a one-time process. It’s an ongoing commitment to maintaining and enhancing your car’s performance. By staying on top of your vehicle’s performance data and making necessary adjustments, you can continue to enjoy a responsive, powerful, and efficient drive with your Fiat 500 Abarth.

RaceChip Warranty and Support

When enhancing your Fiat 500 Abarth’s throttle response with a RaceChip product, it’s essential to note that the company also provides a one-year engine warranty. This warranty covers the engine, turbocharger, and transmission, thus giving you peace of mind as you embark on the ECU remapping journey.

Before starting the engine remapping, verify the compatibility of your vehicle with the selected RaceChip product. Technical support is available to help you through the process, ensuring a perfect match between your vehicle and the RaceChip product.

In addition, RaceChip offers a 30-day money-back guarantee. If, for any reason, you’re not satisfied with the performance improvement after using the RaceChip tuning product, you can return it within 30 days for a full refund.

Enhancing Additional Features

While tuning the ECU primarily increases engine power and throttle response, it can also enhance other features of your Fiat 500 Abarth. For instance, the RaceChip XLR can improve the interior suspension, making your ride smoother and more comfortable.

Similarly, upgrading your engine exhaust system can increase your vehicle’s power. With a more efficient exhaust system, your engine can rid of exhaust gases more effectively, leading to higher engine speeds.

Furthermore, the RaceChip app allows you to adjust your vehicle’s torque efficiency. By adjusting the torque mapping, you can influence the gear-changing behavior for a smoother ride and more efficient fuel consumption. Whether you prefer quick gear changes at lower engine speeds or to keep a higher gear for longer, you can customize this in the RaceChip app.


The Fiat 500 Abarth is an impressive performance vehicle straight from the factory. However, an ECU remap with RaceChip can further enhance its performance, improving power output, throttle response, and fuel efficiency. Moreover, with the RaceChip app, you also get the convenience of real-time performance monitoring and easy adjustments to your vehicle’s settings.

Whether you’re seeking to make your daily commute more exhilarating, or wanting to extract every bit of performance for a track day, the RaceChip products offer a versatile solution. Remember, enhancing your vehicle’s performance is not just about power. It’s about creating a balance that delivers performance, efficiency, and drivability, turning each drive in your Fiat 500 Abarth into an extraordinary experience.
