What is chip tuning?

We were able to produce the power chip series by most complex tests. At the  moment we are on the highest level of  Chip Tuning. Within shortest time  simply and safe installed, it optimizes the power of your diesel car  up to 35 procent.

The new extended version of power chip V-PD  works in principle equal to the already existing chip. The PD engines have several injection nozzles which are separately optimized by our chip. Through this process the power of your car is optimized even more.
These chips are also simple and fast to install:  no opening of the control unit is necessary! The chip is already adapted to your cars engine - readjusting is not necessary usually.

The chip is preconfigured and can be installed with a simple adapter between the original connectors (absolutely
WITHOUT any auxiliary cable).

What is Chip Tuning?


Chip tuning refers to changing or modifying an EPROM chip in a car's or other vehicle's electronic control unit (ECU) to achieve better performance, whether it be more power, cleaner emissions, or better fuel economy.

This was done with early engine computers in the 1980s and 1990s. Today, the term chip tuning can be misleading, as people will often use it to describe ECU tuning that does not involve swapping the chip. Modern ECUs can be tuned by simply updating their software through a standard interface, such as OBDII. This procedure is commonly referred to as engine or ECU tuning. ECUs are a relatively recent addition to the automobile, having first appeared in the late 1970s.

As technology advanced, so did the electronics that go into cars. The ECU in a modern automobile, together with advanced engine technology, makes it possible to control many aspects of the engine's operation, such as spark timing and fuel injection. The ECU may also control electronic throttle control (drive-by-wire), valve timing, boost control (in turbocharged engines), ABS, the automatic transmission, and the electronic stability control system.

Performance gains are realized by adjusting the ignition timing advance. Higher timing may result in higher performance. However, to cope with advanced timing, one must run high-octane gasoline to avoid pre-ignition detonation or pinging. Manufacturers design for a specific timing and this may limit performance accordingly.

In addition, changing fuel maps to coincide with the stoichiometric ratio for gasoline combustion may also realize performance increase. Most manufactures tune for optimum emissions and fuel economy purposes which can limit performance.

Another reason to change the ECU map is if there are engine, intake, or exhaust modifications to the car. These bolt-on modifications alter the way that the engine flows, often causing the air to fuel ratio to change. Without re-mapping the fuel tables, some of the performance gains from the modifications may not be realized.

A common misconception is that the ECU can be tuned to provide different power maps optimized for different driving courses (e.g. race tracks). In fact, once the ECU is tuned for optimal torque at all RPM ranges, there is no reason to "de-tune" the ECU for any RPM. A poorly tuned ECU can result in decreased performance, drive ability, and may even cause engine damage.

Additional Tuning

Manufacturers point out that with the advancement of engines it can be analyzed very exactly there whether the reserves leave still sufficient clearance, which changes are necessary in the engine surrounding field (cooling, fuel injection system, transmission gradation to the existing construction), whether not nevertheless substantial design details must be revised, like e.g. more rigid crank case or the higher loads adapted alloys for pistons and piston rings.
Also interpretation of chassis and brakes are included into these investigations with. Consequence: Tuning is in principle rejected, further details under point guarantee.
 

Experiences to the service life
 

The General German Automobile Association(ADAC) are present for this neither positive nor negative field reports. To consider it is however that such worked on vehicles exist so far only in comparatively small numbers of items. The magazine Gute Fahrt (english: property travel) had afterwards at 100,000 km - with one of Oettinger an engine disassembly lasted accomplish to let worked on trade wind TDI. Up to this odometer reading no wear could be determined, the result refers however only to this concrete vehicle! Vehicle manufacturers indicate anyhow to get cases of damage again and again for (futile) warranty adjustment submitted

Operating licences/pollutant classes
of interferences in ignition and air/fuel mixture leads inevitably to expiring the so-called General operating permit, with appropriate unfavorable consequences according to the energy government.
Absolutely pay attention therefore to the collecting main of an existing type testing by California Air Resources Board (CARB).
A component of this appraisal are exhaust behavior (complex procedure, nothing has to do OUTER ONES with that!) as well as possible further requirements at chassis, type etc. Statements how: the TUEV registers that already to you, if you do not want to make that at all are acceptable. The change of the exhaust gas composition can besides cause that a worse standard than so far is determined and registered. The pollutant class with high order euro 3-D3 today many models keep already, a degradation lead then to according to higher sentences in the automobiles tax.

Guarantee and Insurance

Premiums: The earlier rigid pattern in the liability insurance, which oriented itself at the engine strength, existed no more, nevertheless does not save increase in output the danger that insurers take out and to a higher class assign the concrete vehicle of the past so-called type class. Since there is no uniform procedure here, this, also regarding insurance against all risks part-insurance, should be clarified absolutely before.
Case of damage: One not into the Cars papers registered engine increased output, which was not communicated also to the insurance, to the loss of the insurance protection lead.
 

Guarantee and Warranty

Tuner: These give (isolated) on the upgraded engine a warranty of 1 year (max. 100. 000km pro year). In the case of loss certainly not always to be clearly provable, to which causes the loss is to due, proof difficulties are thus pre-programmed. Negative examples are not present the General German Automobile Association however.
Vehicle manufacturer: Within new vehicle warranty and following voluntary fairness trading (in general. 1-3 years) the adjustment of damage to the engine or also associated “outside” construction units becomes (e.g. Inject - equipment) throughout rejected. This can itself in addition, on completely different ranges, like e.g. the switching or automatic transmission, expand. A proof that the current damage with Tuning procedure does not have to do anything, is difficult according to experience to impossible
 

Technical problem in the workshop

A change of the original state can lead in workshops to complications with the error tracing. Substantial electronics construction units are equipped nevertheless with so-called “error memory”, which cannot supply useful data after reprogramming more. Also within the regular exhaust investigations (OUTER ONES) to searching adjusting and emission values are usable only if this from the data of the operating permit (S. Point 8) comes out

Which Tuner are recommendable?

To deliver evaluations, which would require detailed in each case tests and also later constant contact with these vehicles. With the multiplicity of Tuning company's is not for capacity reasons however with the best will feasible. Test (thus no long-term observations!) isolated in the usual automobile magazines is published, whereby particularly VOLKSWAGEN/AUDI drivers in the magazine property becomes travel (Delius Klasing publishing house, Bielefeld) more frequently find.
