V-tech Tuning - Performance Chip Tuning Files Manufacturer

Our chip tuning offer consists of two different channels of distribution:

  • for individual customer
We can tune your car (virtually any car equipped with ECU), using serial (OBD & CANBUS) programming or just by desoldering and re-programming your ECU flash.
  • for tuner / distributor

We offer quick modification of files sent to us, and all also equipment you may need (serial OBD & CANBUS programmers for cars, BDM interfaces for ECUs, flash programmers). Communication with our company is immediate, using proprietary web interface (faster and safer than e-mail, you can log in and download/upload chips virtually anywhere, where you can acces internet). We deliver tuning chips in less than 1 hour, even on saturdays or late evenings. Prices for files are excellent (contact us for dealer prices).

Over 100 tuners from many countries rely on our job! Click to get access to our dyno tested chip tuning files database.

Performance Chip Tuning Basis

The tuning chip in the context of tuning ia modification of engine control software located in the central control unit (ECU, i.e. the computer,) of the engine. In the terminology of electronics a "chip" means an integrated circuit. Modification of the contents of the external program memory is the most frequent operation in engine controlling computers. The memory is usually located in an integrated circuit called Eprom or Flash memory. The contents of the microcontroller memory is sometimes modified too. In general, the philosophy behind the modification is not important for the results achieved – the most important is the careful development of the program, as well as its versatile modifications, rather than the method of feeding it into the ECU.

With respect to the results of the tuning, chips could be classified into two basic categories:

  • tuning chips for cars with turbochargers or other type of forced induction,
  • tuning chips for normally aspirated cars, i.e. without any forced induction.

Usually, a normally aspirated (N/A) car might be tuned by approx. 8% of their power and 8-10% of the torque. It is done by a modification of some fundamental parameters: fuel pressure, time of the beginning of dosage, ignition advance angle and the calibration map of the lambda probe. Some automobiles may be improved significantly, whereas the modification of others is not possible at all. From the user's point of view it is sensible to combine mechanical and electronic modifications. If the modifications are well matched (e.g. a sports camshaft and a suitable tuning chip) the power gain can exceed 15% of the power and torque. Fuel consumption does not change or it decreases a little (as a result of the fact that a part of the power increase comes from the ignition advance, so it does not require more fuel).

Cars equipped with a turbocharger (both the diesel and petrol ones) can be tuned by 20% to 30%. In this case, apart from the parameters mentioned above, pressure characteristics of the turbine is modified (of course in turbodiesels the fuel injection angle is adjusted – not the ignition anticipation angle). The fuel consumption decreases by approx. 5% for turbodiesels and increases by approx. 10% for turbo petrol engines. We give a 2-year-long warranty for the software and the modules.
