What we offer?

At JR Auto Performance we provide world class automotive tuning software for the newest BMW’s, Mercedes, Porsches, Vag Groups, etc. Our software is of the highest quality available in the industry, free of bugs or errors. We own high quality programming equipment that specializes in reading and writing today's advanced factory Engine Control Units (ECU’s).

All ECU programming is performed at our location either by flashing the ECU through OBD or by programing the ECU on the bench

We use advanced software which is prepared to modify the memory contents of ECUs.

Additionally we own factory level diagnostic equipment for BMW, Mercedes, Porsche, VW and Audi. We can easily diagnose, log or modify software at a dealer level and even update firmware if required.


What is Chiptuning?

A car powered by an injection system uses a device called Electronic Control Unit (ECU).

ECU is a specialized computer responsible for the parameters of the engine performance under every condition of car speed and load. To ensure that parameters are correct under every condition, a map of fuel supply and ignition control is available for the ECU. This map specifies approximate values of power supply and steering for current conditions in the engine. A special program, also recorded in the ECU, converts this map and corrects it according to the data provided by the indications of the lambda probe, knocking combustion probe and some other sensors.

Parameters recorded in the ECU, as well as the program, have been designed by the manufacturer at a level lower than optimal. There are three main reasons for such a situation:

  • Firstly, sometimes a car operates for a long time despite occasional mechanical damages. It is supplied with poor quality fuel (in general, each European car is calibrated for 91 octane, except French and English cars - 94 octane), or fed with inferior quality oils and maintenance materials. On the one hand, the margin of safety assumed by the manufacturer prevents damages caused by the users, who do not follow the proper maintenance schedule. On the other hand it results in substantial fuel consumption and a decrease in engine power. This margin amounts to no less than 15 % for cars without air-compressors and about 50 % for cars with air-compressor - that’s a half the power!
  • A car has to operate at a low fuel consumption level. However, as international standards determine the test speed rates (i.e. at 90 and 120 k.p.h), manufacturers are making their best to reduce the possible performance. Consequently, fuel consumption at these speed rates in 4th and 5th gear create artificial "gaps in acceleration". Big limitations imposed on the revolution range below 3000 RPM are intended to improve the city drive performance, resulting in decreased power and poor engine performance. As you know, people tend to buy economical vehicles. That’s why the acceleration is of secondary importance to an average customer, which results in car manufacturers using the strategy described above.
  • European and North American car owners are troubled by taxation. The majority of cars offered on the German market are characterized by lower power than their Japanese or American counterparts, despite the same torque. A 1400cc Vtec Honda available in Germany has a 75HP engine. Whereas the same Honda in Poland has 75 or 90 HP. In Japan, the same engine is capable of 100 HP. All of it depends just on the tax thresholds but really only limited by the software in the ECU

You do not have to lose this power! We can help You gain it back

If you look after your car properly, follow the proper maintenance schedule and you use at least 91 octane fuel from reliable filling stations, we will give you a chance to take back the horsepower the manufacturers of your car refused to give you. You can make your car stronger by about 10 per cent, or even by as much as 30 per cent (cars with turbines) just through application of an appropriate chiptuning performance software.

As you can see, chiptuning means modification of the computer software which controls the engine. It is intended to provide higher efficiency, power and torque, and possibly slightly decreasing fuel consumption when driving in unchanged style after chiptuning modification.
