What is chiptuning?

Chiptuning is the tuning of an engine for better performance. Nowadays, every car contains a computer. This computer controls the engine and is called engine management or ECU (Electronic Control Unit).

The engine management is the brain of the engine and regulates the engine running based on various values, including turbo pressure, throttle position and injection amount.

By adjusting the software, we tune the engine differently. If possible, we always remove the speed limiter from your vehicle.

of the motor

The vehicle manufacturer has set the engines to a default value. We determine new settings based on the engine’s technical data (turbo, fuel pump and drivetrain). We want to get the maximum out of it in a safe way. When tuning an engine, improved drivability is just as important to us as an increase in power and torque.

Why do not tune the

Manufacturers offer motors in various designs. The motors are positioned to fit into the product range. For cost reasons, an engine block is therefore supplied in different power variants. This creates leeway, which we take advantage of.

Tuning is a profession

All engines today are equipped with advanced injection technology. In recent years, diesel engines have increasingly used common rail technology with piezo injectors, while gasoline engines are increasingly equipped with direct injection.
Tuning requires a lot of knowledge and experience. As you can read about us here, we have a team that has been in the business for years. That’s why we know what we can get out of your car in a safe way

An optimal ratio of
the air/fuel mixture

When chiptuning, our team adjusts various parameters in the engine management. If you add a little more air and inject more fuel, your engine will deliver more power. It is important that the air/fuel mixture remains in an optimal ratio. We pay a lot of attention to that.

An optimal fuel mixture favors service life and ensures less pollution. A mixture that is too rich leads to higher consumption and more pollution. A lean mixture leads to a higher engine temperature and to the fact that the engine can no longer start properly.

One side effect of our chip tuning is that your car drives more economically because the engine has to make fewer revs and no fuel is lost. The fuel savings is a byproduct and unfortunately not always guaranteed. Your driving style also plays a big role in this. You also have more torque available, so you can drive in a higher gear sooner.

Tuning according to the highestTÜV requirements

On request, we supply all tunings with TÜV certificate which require an individual acceptance which is calculated separately. The CO2 and consumption measurements in an ECE cycle remain at least the same with us.
With the chiptunings developed by us, we keep the emission values under control.

We adjust the engine so that the CO2 emissions and fuel consumption remain at least the same. On our test bench, we simulate an ECE cycle with an exhaust gas analysis. An exhaust analysis is important for cars in a favorable tax class to continue to meet government standards. Tuning from Tuningbase provides even more driving pleasure!


Since not every engine management system is programmable, we have developed two tuning options to give all engines an improved tuning. This way we can get the best out of your car. Both methods guarantee a high-quality tuning.


Programming the original engine management
(software chiptuning).

During chiptuning, our team adjusts various parameters in the engine management. If you add a little more air and inject more fuel, your engine will deliver more power. The software of the original engine management system is read via diagnostics or directly on the ECU (debugging mode). Then we rewrite the software and put it back. The advantage of this method is that we can influence all values. Even values that are not essential for chiptuning. It is important that the air/fuel mixture remains in an optimal ratio. We pay a lot of attention to this.
An optimal fuel mixture favors durability and ensures less pollution. A mixture that is too rich leads to higher consumption and more pollution. A lean mixture leads to a higher engine temperature and to the engine not being able to start properly.


Programming of a free

When programming a freely programmable ECU, we replace the original engine management system with a freely programmable ECU. In this way we adjust the performance of your vehicle to your own wishes. This method of chiptuning offers much more possibilities when installing a different turbo or larger injectors. We use engine management systems from AEM, Vipec, Autronic, Hondata and Haltech. The Mitsubishi EVO IX, Nissan 350Z and Hyundai Genesis are examples that can be tuned this way. We use a free programmable ECU for racing and rally purposes, but there are some vehicles for which this is the only tuning option.Tuning detection

. The manufacturer has equipped the ECU of some new models with tuning detection. If a tuned vehicle is locked to a diagnostic device during service, for example, the factory can be alerted to the chip tuning and the warranty will be voided.


The development of a chiptuning for a new engine type can take weeks. Recalibrating your vehicle will take at least 2 hours. We want to explain exactly what we do to keep you happy on the road. You can also read more about us here. What our mission is and what is so unique about Tuningbase.

Phase 1

When a new engine or model is launched on the market, we first carry out technical studies on the engine and powertrain. It is important for us to know the characteristics of the turbo and the injection system. Then we read an engine of the type in question and see how safety can be bypassed. We examine and analyze the original software completely. In doing so, we analyze the key fields that are important to us. This way we know where the injection control, rev limiting, turbo pressure and torque limiting are set. In some cases, tuning certain (atmospheric) engines is not worthwhile. We are always very honest about this, because we want to ensure a good result.


As soon as we have a car with a new engine available, we test the vehicle in its original condition with diagnostic equipment and a performance measurement on the test bench. We then compare the values requested by the ECU with the specified values.


After the test, our team goes to work and we recalibrate the engine. Using diagnostic equipment, we calibrate our settings to guarantee an optimal air/fuel mixture ratio. For gasoline engines, we also talk about the ‘lambda’ values. The developed tuning is adjusted for daily use and we always keep a safety margin. The engine is not loaded with maximum load. The entire development process can take weeks.

Research & Development

Besides the development of chiptuning, we do even more. Together with Injen, we develop new intake systems and manufacture customized intercoolers and compressors for various vehicles.

Phase 2


Our engineers develop the tuning software of your car on a Superflow (Tuningbase Gent) and Dynocom (Tuningbase Houten) four-wheel dyno. For a correct measurement all four wheels are turning. The cooling of the engine is variable to ensure a realistic measurement. With diagnostic equipment we calibrate the desired and delivered values of the turbo and injection system. While the engineers optimize the software, we keep a close eye on the injection, injection quantity, fuel mixture, turbo pressure, and intake and exhaust temperatures on the test bench.
After making an appointment, we make arrangements so you don’t have to wait unnecessarily. Once your car is in, we first diagnose it. For older cars, we check the condition of the engine and always look for trouble codes. If necessary, we take a test drive, where we examine the running engine. Then we read the software from your car’s ECU and adjust it accordingly. We do this using programming that we have developed.

. Optionally, we check the performance on the dyno. We always do a test drive to see if the air/fuel mixture ratio is set correctly. Tuning your vehicle will take at least 2 hours (2-3 hours on average). Individual adjustments, e.g. for racing purposes, are of course possible and it is also possible to get the best out of an engine. However, we do not give any guarantees and different prices apply.


Passion for the job and a professional approach ensure that we deliver solid and long-lasting car tuning. To emphasize our quality, we guarantee our software and offer an additional software warranty.

. After tuning, you don’t have to drive your car. This is an urban myth that some tuners will tell you to postpone possible disappointment. We don’t like that. Our goal is 100% satisfaction. Of course, it is still advisable to let the engine warm up properly and cool down after a quick run. This does not change even after tuning.

If you are not satisfied with the chip tuning, you can always contact Tuningbase customer service. We can then schedule an appointment to further customize the tuning to your specific needs. So get a quote today and see what can make your car better!
