FAQ - Frequently Asked Questions

Here we show the most frequently asked questions and answers from our experienced engineers. In case you do not find an answer to your question, please do not hesitate to contact us - by phone or e-mail. We are pleased to answer any of your questions.

Which fuel will I use after chip tuning ?

If you have diesel engine then certainly use diesel :-).

Bio diesel is a suitable fuel also but do expect a decrease of engine power.

n case your car has got a petrol engine refill the tank with petrol that has got a higher octane number. This means that if your car ran on Natural 95 before, it is highly recommended to use Natural 98 from now on.

Basically, it is about power increase - Natural 98 is more powerful and contains more octans that prevent "engine knocking".

The ignition is advanced a little inside the Engine Central Unit - therefore the increase of engine power is considerable.

I got my car adjusted by another service centre. I am in doubt over the actual parameters of my car now. How can I verify that I have got what I paid for ?

It is very easy - order a test.

After testing you will receive the test results - diagrams and graphs reflecting engine power and torque actual values. If these parameters do not match with the one you received from the service centre then we strongly recommend you to make a complaint and ask for either a new adjustment or your money back. It is necessary to test your car before and after adjustment.

Can chip tuning damage an engine or decrease its life expectancy?

Yes, it can indeed. Poorly conducted work can damage your Engine Central Unit and eventually the whole engine. It is in your own interest to avoid the doubtful work of apparently cheap motor mechanics and to contact a reliable and experienced service centre that can provide you with professional services.

For example - damage to so called failure diagnostic routines can lead to engine damage and damage to accessories. Damage can also happen if the adjustment is "sharper" than the recommended optimal parameters which are pre-set in every Engine Central Unit. This will lead to a decrease in engine life expectancy in routine use. Therefore this kind of adjustment is only done at customers' special request after consultation with an engineer who will make them aware of possible damage. Depending on the range of adjustments and engine usage, this could lead to engine life expectancy being lower by about 20 thousand kilometres or more.

Warning! If you intend to use your adjusted car for rally or other road competitions you should always make our engineer aware of this before adjusting your car. He will then recommend you the most suitable car care programme.

When chip tuning has got so many advantages why does the car manufacturer not deliver the engine adjusted already?

You can also find out more to your answer in the introduction part regarding chip tuning. To answer your question, unfortunately it is not possible to do this. Car manufacturers have to take into account a lot of requirements for engine and Engine Central Unit development and find a middle way, in this case actually a compromise, between the range of requirements. Not only does the car producer have to fulfil certain regional restrictions, such as for exhaust emission, but also provide the lowest fuel consumption. They also must take into account differentiated fuel quality, the contents of exhaust emission of low fuel quality and lax care of car owners for their engine.

Another important aspect is the financial cost of running the car. There is a different car tax system in different countries. In some you have to pay tax according to the volume of cylinders (as in our country) and in other countries you pay tax according to engine power. From all these restrictions, the engine becomes conservative and inefficient. But if you are willing to adhere to regular servicing and make a compromise regarding consumption you will have enhanced engine power.

What cars are preferably adjusted the most?

Based on our experience we most often adjust TDI engines. First and second place belong to engines 1.8T and 2.5 TDI V6. In third place is AUDI - especially A4 and A6.

There is also increased interest in adjustments of SKODA Fabia with all engine types and TDI PD engines. Adjustments of VOLVO, MERCEDES, BMW and SKODA Felicia are not so common.
