FAQ

For naturally aspirated engines, i.e. without supercharging, you can safely increase the power by about 2-10%, for supercharged (turbo) engines, the gain on power without compromising durability can be 10-35%.

Modifications for motorsport Chiptuning is currently one of the most popular ways to raise power, at a relatively low cost. The possibilities come from the fact that the factory control software is made in such a way as to ensure the lowest possible fuel consumption, be in harmony with the ecology and have a safety margin for the use of bad operating measures and simple ignorance of the user. With extensive expertise, experience and measuring devices, you can therefore improve its parameters without harming the engine.

Individual chip tuning for off-road motorsport vehicles

Our tuning software is adapted to each vehicle for all vehicle characteristics. Includes and maintains all standard vehicle software specifications. Our goal is the error-free transmission of all individual vehicle-specific data to the tuning software, incl. vehicle and engine identification numbers, gearbox types, modules, diagnostic identifications, fail-safe programs. This corresponds to the natural quality deviations of the components supplied by the supplier (in the engine construction, e.g. pistons, heads, manifolds, turbochargers, exhaust systems, etc.). As a result, your vehicle behaves and can be serviced and diagnosed like any standard vehicle. Manufacturers use dozens of new software versions every day, which are developed for individual pallets of engines and vehicles and programmed in the vehicle engine ECU.
You can distinguish among others:

1. Vehicle type, gearbox version and vehicle driveline ...
are of course primarily decisive factors in software tuning, i.e. there are differences between the designs of individual vehicles, also between identical engines
Rear, front or all-wheel drive: Quattro, X-Drive, 4-Motion, 4-Mtic etc.
Sedan, Coupe, Cabriolet, Station wagon, SUV
5-speed manual, 6-speed manual, S-Tronic / Tiptronic, MultiTronic, DSG, POWERSHIFT, 5G-Tronic or 7G-Tronic etc.

2. Characteristics of the engine
Of course, differently tuned software also changes the characteristics of the engine. Therefore, an automobile company is able, with the same engine, with differently tuned software, to produce a diverse range of vehicles associated with its automotive marks. Each sign of a vehicle, as well as each type of vehicle, therefore receives its own slightly modified engine characteristics, without the need to re-develop the entire engine.

3. Mechanically identical engines - may have different performance variants
For example, almost all manufacturers now offer mechanically identical or almost identically designed engines with different performance variants. The more powerful and usually also more expensive performance variant, which is otherwise almost mechanically identical, often only has revised software in the engine ECU.

4. Deviations of series engines within series and supplier
The manufacturer produces, for example, 1000 engines with a rated power of 150 HP in series. After final assembly, these motors usually undergo an engine test bench test of approximately 20 minutes to verify mechanical functionality and determine power rating and maximum torque. However, the production of engines is subject to the so-called serial deviation, i.e. due to the different mechanical tolerances of individual components (piston, cylinder head, etc.). Of these 1000 engines, only about 330 will have the desired 150 HP. Another third of these engines will be above 150 to 160hp, and the last third will be less powerful, below 150hp, in the 140-150hp range. In order to compensate for these deviations, the software versions are uniquely adapted by the manufacturer to the engine series, i.e. by means of the ECU software the individual engines are adjusted to the rated power. There are also variations and stability characteristics of the individual components supplied by the vendors that need to be included in the ECU software. For reasons of cost, quality and logistics, it is common to use different suppliers for the same vehicle parts.

5. Fuel quality and emission standards
Basically, there are currently two different vehicle designs with regard to emissions and fuel quality. For us, however, only the so-called EC standard for all European vehicles. US vehicles usually only run outside of Europe. Just change to 98 octane fuel (super plus), most Otto engines have a noticeable improvement in "revitalization" and agility. Some manufacturers already recommend, especially with higher performance engines (eg M3, M5, Porsche 996, E55 - CL55 etc.), refueling with 98 octane fuel. Although most vehicles are only run on 95 octane fuel (super unleaded). Therefore, most standard production vehicles cannot run on 98 octane fuel. A good example is that Italy delivers the same vehicles as Germany, with identical performance figures. However, in Italy 98 octane (super plus) fuel is not available. Italy only has 95 octanes (super euro). However, if the necessary fuel for the rated power is not available nationwide, the vehicle would have to be delivered with a lower performance, however in Italy this is not done. A similar situation occurs for all turbodiesel engines in terms of the sulfur content and the cetane number of the diesel fuel available ...

6. Software Updates

While we regularly update our computers, tablets or phones so that they run faster and more efficiently and use less energy. The ECU and TCU can also be updated as continuous research and experience shows that better performance can be achieved for the engine or gearbox. You can think of a software update.

Modification of the software of the TCU automatic transmission controller - DSG, S-Tronic, PowerShift and hydrokinetic: 6HP, 8HP, 5G-tronic, 7G-tronic and many others.

Changes to the gearbox control software can meet the needs of a sporty and ambitious driver.
We will adjust the following parameters to specific requirements:

• shorter switching times
• changeover at engine speed
• freewheel engine speed when changing full load
• engine speed limitation on request
• adaptation of the torque limit when reprogramming the engine electronics
• launch control optimization
• shorter response times of shift paddles
• higher setting of forced up gear in manual mode
• Deactivating the kickdown function
• starting or clutch adjustable more smoothly
• Oeco mode with special switching operations
• If necessary, the modification maps will be adjusted in D or S mode. For cars with active / variable exhaust, we recommend only adjusting the S mode according to your wishes, because the exhaust in D mode sometimes has different cruising parameters.

In the context of Chiptunig, there are car models that can no longer be driven without modifying the software in the TCU gearbox. In these models, the correction is automatically included in the price of the chip tuning.

Not all automatic transmission models require modification of the TCU software as power and torque increase. It depends very much on the needs of each user. About 80% of users are satisfied after modifying the engine software, even without increasing the torque limit. 20% of users admit that during sports driving, the torque limit is too high immediately after shifting gears and therefore needs to be adjusted. These additional tweaks are available as well as the aforementioned improvements.
Here are some examples that require modification.
Gear type / modification required from NM / Max. Clutch mechanical torque
DQ200 / (Transverse) for example 1.4TSI, 1.8TSI / 250NM / 380NM
DQ250 (transverse) e.g. Golf 5 2.0 TFSI, 2.0TDI / 400NM / 480NM / 700NM (modified clutch)
DL251 (longitudinal) for example Audi A4 2.0 TFSI / 400NM / 480NM
DQ500 (Transverse) e.g. 2.5 TFSI / 550NM / 750NM
DL501 (longitudinal) for example Audi A6 3.0TDI / 550NM / 750NM

We also copy / clone TCU drivers, necessary for most modern gearboxes when installing a used gearbox for another car.

For racing use, we are able to modernize gearboxes according to customer expectations. Whether it is shifting, installing a differential lock or a heavy duty clutch, please get in touch. We can meet your requirements. We needed your vehicle for such modernizations for a long time. Price depends on development, mechanical and testing work. The service time required varies by model, type, software version, desired settings and associated test work and will be charged on a per-cost basis.

Yes, at any time we can restore the serial program that was.

We have legal access to serial programs used by manufacturers, as well as to updates and previous versions.
