What is Custom Car Coding?

Custom car coding involves modifying your car’s electronic systems to customize its features and performance. It is done by accessing the car’s computer system, also known as the Electronic Control Unit (ECU), and changing its settings. This can be done through specialized software that connects to the car’s OBD-II port, which is usually located under the dashboard.

Custom car coding allows you to change various settings in your car, such as the lighting, sound system, throttle response, and other performance metrics. It can also give you access to advanced features that may not be available in your car’s default settings.

Welcome to Custom Car Coding! Our company was established in 2019 to address the frustrations that many Ford Ranger, Raptor, and Everest owners experience. Our founder, Mitch, personally experienced these frustrations when he purchased a Ranger Raptor from the first shipment in Australia. He was annoyed by incessant chimes and horn honks when exiting the vehicle, an intrusive start-stop system, and most importantly, the factory transmission tune.

Unfortunately, Ford was not very helpful and claimed that the Raptor transmission was functioning perfectly. Mitch’s hope for a solution was fading until he started tuning the 10R80 transmission himself and noticed significant improvements. With over a decade of experience as a diagnostic technician in the automotive industry, Mitch made it his mission to optimize Ford’s 10-speed transmission to perform as it should have from the beginning.

After more than 12 months of daily tuning and adjustments, we finally released the tuned transmission to beta testers. Their feedback helped us perfect it for the official release.

Since then, we have diligently worked to make similar enhancements for any contemporary vehicle that did not meet the mark with its original transmission tuning. At CCC, we firmly believe in the pursuit of perfection, which is why we continuously fine-tune and improve our tunes long after their initial release.

Our goal is to eliminate the frustrations that come with modern automobiles, just as Mitch aimed to do with his personal Raptor.

We are incredibly grateful for your ongoing support and patience as CCC naturally grows. We do not believe in aggressive marketing tactics; instead, we strive to provide a product of great value and a level of service that speaks for itself.

We hope to hear from you soon!

How Does Custom Car Coding Work?

Custom car coding involves using specialized software to access the car’s ECU and change its settings. This software can be downloaded onto a laptop or tablet, which is then connected to the car’s OBD-II port using a cable. Once connected, the software can read and modify the car’s settings.

The software used for custom car coding varies depending on the make and model of the car. Some popular software programs include VCDS (VAG-COM Diagnostic System) for Volkswagen and Audi cars, INPA (BMW INPA Software) for BMW cars, and FORScan for Ford cars.

Before attempting any custom car coding, it’s essential to do research and understand the risks involved. Incorrect coding can damage your car’s systems, and it’s recommended to seek the help of a professional if you’re not experienced in car coding.

What is custom code?

What exactly is custom code? To better understand, let’s use a metaphor. Imagine that code is comparable to a vehicle, specifically a blue Honda Civic.

Imagine you have a desire to own this specific blue Honda Civic. In order to obtain it, you would have to assemble the car yourself, build the engine, paint it, install all the necessary electronics, and ensure it meets all legal requirements for road use. Additionally, you would be solely responsible for driving and maintaining the vehicle. If any issues arise, whether it be breakdowns or the need for enhancements or fixes, you would be personally accountable for resolving the problem or would need to hire someone to take on that responsibility. This is essentially what custom code entails.

On the contrary, envision receiving a Honda Civic, or code, that comes as a ready-to-drive car package. You’re then informed that if any issues arise with the car, you can simply bring it to the nearest authorized Honda Civic Repair center for free repairs and maintenance whenever necessary. In this scenario, the code is not customized.

As you can observe, creating, maintaining, and modifying custom code is a time-consuming and complicated process. However, it offers the advantage of being able to support any use case.

Custom code: Point-to-point integration

Custom code takes on various forms and serves different purposes. Frequently, it is utilized to establish connections between two systems, referred to as point-to-point integration. Point-to-point integration necessitates developers to construct custom code that links multiple applications, systems, data, and devices within an organization.

While custom coded point-to-point integration facilitates quick and easy communication between data, it lacks future-proofing capabilities and scalability. This type of integration creates individual connections between data, resulting in a “spaghetti architecture” that is intricate, fragile, and challenging to maintain.

Due to the constantly changing business requirements and initiatives, the existing spaghetti architecture poses challenges and inefficiencies when it comes to making minor modifications. While custom coded, point-to-point integration may seem like a quick fix in the short term, it actually creates long-term complications and hampers scalability and business agility.

To overcome these issues, enterprises need to move away from custom coded, point-to-point integration and adopt a new approach called API-led connectivity. This approach is based on reusable, purpose-built APIs that enable easy plug-and-play integration, similar to connecting LEGO blocks. Applications are connected to data through modern, managed APIs that can be easily discovered and controlled through governance.

Beyond custom coded point-to-point integration

API-led connectivity empowers retailers to integrate data from different applications, systems, and devices, allowing them to create new applications or extract more value from existing ones. Unlike custom-coded point-to-point integration, API-led connectivity simplifies change by using APIs to connect assets, systems, or data. Adding, changing, or removing assets becomes a seamless process of plugging or unplugging.

Why Consider Custom Car Coding?

Custom car coding offers many benefits, including:


Custom car coding allows you to personalize your car’s features and functionality to suit your preferences. Whether you want to change the lighting, sound system, or performance metrics, custom car coding gives you the ability to do so.

Advanced Features

Custom car coding can give you access to advanced features that may not be available in your car’s default settings. For example, you can add an automatic start-stop feature to save fuel, or enable a hidden performance mode for a more aggressive driving experience.

Cost Savings

Custom car coding can be more cost-effective than buying aftermarket parts or upgrading to a higher trim level. For example, instead of buying a new sound system, you can code your car’s existing system to produce better sound quality.

Increased Resale Value

Custom car coding can increase your car’s resale value by making it stand out from the crowd. If you’re selling your car, having unique features and functionality can make it more appealing to potential buyers.
