RaceChip started in 2008, when founder Manuel Götz wanted to take his passion for automobiles to the next level. They initially operated and sold their tuning products within Europe, but in 2010 they expanding their dealer network to offer their products globally.
Today, RaceChip is one of the biggest and most well-known aftermarket tuning companies in the world. Their focus on building quality tuning systems which increase horsepower without sacraficing reliability has allowed them to serve hundreds of thousands of customers all over the world.
Why Choose RaceChip?As you probably know, there are a lot of tuning companies within the automotive aftermarket. Some are small niche tuners who specialize in tuning specific platforms, such as Ford EcoBoost, and some tuning companies offer products for nearly everything. RaceChip is one of the companies with a very broad product catalog.
Quality of Tune FileHow much time is spent developing a tune file or tuning product makes a massive difference. On the surface, it may seem like advancing ignition timing and optimizing air/fuel ratios, but creating a quality tuning product is much deeper than that. RaceChip tuning doesn’t simply turn everything to the max - it optimizes intelligently within your engine’s design limits.
Customer ServiceWhen you’re installing aftermarket tuning products in your vehicle, the last thing you want is an issue during installation without a clear way to solve the problem. RaceChip provides easy-to-understand instructions with every RaceChip tuning box. If you run into an issue during install, RaceChip can help you with their knowledgeable customer service team.
Bluetooth ConnectivityUnlike most tuning solutions, RaceChip tuning boxes allow you to connect your smartphone to the tuning box to make changes. Straight out of the box you’re able to switch between three performance levels: Efficiency, Sport, and Race. If you need a customized tuning file, RaceChip can provide a modified tuning file which you can install on the tuning box.
Tuning Box vs ECU TuningWhat makes RaceChip special compared to many other tuning companies is the type of products they offer. Many tuning companies offer ECU flashes AND tuning boxes, but RaceChip offers just tuning boxes.
A “tuning box” works by capturing sensor outputs such as MAF, Oxygen Sensors, TPS, Ignition, etc, and modifying the signal before the vehicle’s ECU receives the signal. With this type of system, your OEM ECU is left completely stock.
Unlike many tuning boxes on the market, RaceChip tuning boxes are intelligent. They work more like small computers and modify sensor signals in real time, compared to traditional tuning boxes which don’t modify the signals in real time.
Compared to ECU flashing, installing a tuning box is very easy and does not require overwriting your OEM ECU with a new file. With a “plug and play” design, it’s easy to uninstall a tuning box without a trace of it ever being installed on the vehicle.
