General Information

Why is Quality that important?

A reputable chip tuner will always develop the software especially for your vehicle, which is reflected by a significant increase in performance, a comfortable ride and a lower fuel consumption. All safety functions of the vehicle persist and no thresholds are met or even exceeded.

Dubious chip tuning companies buy cheap software tuning files from the internet, and this pre-developed software, which is basically some kind of generic file for a whole group of engine models, will be programmed into your car. To prevent, that these not fully compatible files throw any error codes or bring up any kind of warning lights or messages, all security functions of the car/engine are simply disabled. Needless to say, that the car will turn into a time bomb.

Beside this dangerous behaviour, there are a number of drawbacks which you might not thing from the beginning.

'Side effects' of bad chiptuning software:

  • Most of the time it is impossible to set the car back to original version. The original Software is not stored, and it is nearly impossible to put an generic ECU back to stock and enable the safety functions again. Buying a new ECU is most likely the only solution.
  • It might be dangerous to the engine or turbo. Preconfigured files are often used for same engines/ECUs with different turbos and original stock power. You might imagine what will happen if you put in the tuned software of an 170hp stock car to an 100hp stock car.
  • To prevent troubles, all the security features are disabled, if you fe. drive to high mountains, the turbo will spoil.
  • No warranties at all.

Advantages going with UPsolute (or most other reputable chiptuning companies):

  • The software is tuned to each vehicle
  • All safety functions are still working
  • Power reserves will be used , but never exceeded
  • Set the car back to original mode (eg, vehicle sale) is at any time possible and free of charge
  • The original software is stored on a high-availability system
  • Money back guarantee

We don't want to tell you that we are the only reliable and serious chiptuning supplier out there, but please be warned, that especially during the last few years really a lot of black sheeps jumped the train, and try to sell cheap software. Just make sure to be aware of the possible consequences. 

What is Chiptuning / ECU remapping?

At the professional chiptuning (remapping) , the software of the ECU (Engine Control Unit)  is optimized individually for each car. The result is the release of power reserves and lower fuel consumption. UPsolute will never exceed the specified limits of the car manufacturer, which would have a negative effects on the driving experience (behavior) and the engine wear.


Why UPsolute?

Only UPsolute offers the following additional services completely free of charge:

  • 14 days money back guarantee
  • Free back to stock
  • Free software updates
  • 3 year warranty on the engine control unit
  • Individual adjustment to your vehicle
  • 100% Satisfaction Guarantee

How are power boxes working (also called tuning boxes)?

These boxes (also called tuning box) are connected before the control unit and deliver the vehicle falsified sensor values​​ which results in an increased performance, but less than in a real chip tuning. Through the distorted sensor values​​, the vehicle alarming system is no longer working and the car can not switch to the emergency program or stop the engine in case of a problem.

Technical Details

Chiptuning and the secret behind it

To understand the Chiptuning process, you need to know where and how the optimization will take place. The optimization will be exclusively performed in the ECU (Engine Control Unit), that means the engine itself will not be modified in any way, only the chip (Eprom/Flash) which contains the data used for the engine management. The OEM software will be optimized and programmed to a new chip. To fully lift the secret, we need to go more into detail...


How it is done (OBD vs. BDM vs. Soldering)

There are four different processes, how the software can be read from the control unit and be rewritten:

Variant 1 soldering ( Replace the chip in the engine control unit):
The ECU have to be removed from the car and the chip will be removed (unsoldered). The original software is then read using an EPROM programmer. During the software is optimized by a chip tuner, a socket can be soldered. This has the advantage, that you can replace the chip simpel at any time without soldering. The tuned software is stored on a new chip - the original chip remains unchanged and can be re-installed into the socket anytime.

Variant 2 OBD (read / write via the service interface ):
Via the diagnostic interface of the vehicle, the software can be read/write with an appropriate tuning tool to the ECU. This method requires neither mechanical tasks nor soldering.

Variant 3 BDM:
In this method soldering is also not required, but the engine control unit must be removed. Inside the ECU a standard BDM interface can be found, which allows a read or write process of the software.

Variant 4 Tricore:
Similar to the BDM procedure, the internal interface of the engine control unit is also used to read / write the software. Here it is also necessary to solder 3-5 pins to perform the tuning.

The ECU - History and Benefits...

The very quick development of the technologies during the last 3 decades has of course not passed the automotive industry. Of course the automotive industry benefits very much from the new technologies, but in fact the end user benefits the most. We recognize this mainly at the new cars with good performing engines, less consumption, better handling and improved safety. Today modern cars are equipped with electronic Engine management systems, it does not matter if it is a carburetor like central injection, the much more effective multiport injection or a direct injection with common rail technology with electronic charge pressure control.

The most important development was of course the ECU (engine control unit). This device basically consist one or more small microcomputers which are responsible for the regulation of the engine. The microcomputer runs a program which is stored in a Memory (Eprom/Flash) device. The ECU is responsible for the whole engine management and controls, verifies, navigate and adjust all the important functions of the car/engine. This all happens under consideration of the current load condition of the engine in conjunction of the RPM and environment variables (outside temp., air density, engine temp., ...). This all is possible through the information of many sensors which are capable to measure fe. Pressure, temperature, RPM, speed and amount of air with a very high precision. Then the ECU reads the stored values out of the predefined maps for the injection, ignition, charge pressure, lambda, ... In this way, all the time the best possible ignition timing and the optimal amount of fuel in combination with the correct charge pressure is calculated out of the maps in conjunction of all the sensor values.

All this data is optimized at the chiptuning process. That means the maps for injection (at gasoline/petrol cars also ignition) and charge pressure, are measured in conjunction to each other in the whole RPM band, recalculated and with a very detailed computer programing in relation to load and RPM optimized. This is happening in a way that the maximum possible power and torque is gained, while the tolerances for the long life time of the engine is still kept, and the maximum possible fuel economy is reached. Keeping all this in mind, a noticeable power increase and also a stronger torque of the engine is gained. Power and torque improvement of 20-30% at Turbo engines, and 8-12% at normal aspirated engines are realizable, which causes an high improvement for acceleration, agility and top speed The engine will be more agile and stronger, while the lifetime, and the every day use of the engine is at liable use and regular service intervals the same as at the stock setup.

The main purpose at normal gasoline cars is the regulation of the requested and maximal possible amount of injection. Since the Air/fuel ratio needs to be very exactly to let the catalytic convertor work flawless, the injected amount of fuel depends on the amount of air that is available. In addition the optimal ignition point needs to be determined, when the compressed air/fuel mixture is fired. If the ignition point is to late, the consumption will raise, if it is to early the car will start pinging. In addition the ECU has many other purposes, which will not be changed.

At modern diesel engines the amount of injection is calculated out of the amount of Air, air pressure, outside temperature, RPM and load. This is needed to keep the emission restrictions. At turbodiesel engines, beside this the charge pressure and charge volume of the Turbochargers needs to be defined load and RPM depended. All these information are stored in the Eprom/Flash of a modern ECU. Out of this values (maps) the ECU calculates the at a special RPM/load condition possible or needed amount of fuel injection.

This are the most important functions that are optimized

  • Ignition control
    To use the fuel in a effective way, it's important, to calculate all the time the best possible timing in relation to the RPM, load, temperature and other control signals. At diesel engines - the optimal injection pressure.
  • Injection control
    In Relation of the available amount of Air, RPM, load and other correction factor, the electronic calculates the needed injection time and amount. This ensures the reduction of fuel consumption, a reduction of emission, and a gain in the engine power.
  • Charge pressure control 
    At Turbocharged engines, additionally the charge pressure is calculated to raise the benefit of the above explained settings.
