What is the chip tuning? All modern petrol and diesel engines are controlled by Engine Control Unit (ECU) where the values of the different parameters are set in the factory. Through special hardware these values are read then they are modified and again recorded in the control unit and more specifically in the chip located in the control unit.

What is the chip tuning with additional module? Depending on the different systems used in modern electronically regulated petrol and diesel engines an exchange of data is performed   between the Engine Control Unit (ECU) an the fuel-injection system. The relevant chip tuning module RAPID or RAPID BIKE I, II, or III makes a connection between the ECU and the fuel-injection system that at definite momentums or permanently is involved in controlling the engine.

Why the manufacturers set the automobiles yet in the factory? By rational resp. economic reasons automobile manufacturers make cylinder unit, that can be advantageously equipped with additional components as different makes and models turbochargers, injection systems, fuel-injectors and most of all modified fields of characteristics that are programmed in the ECU in advance.  Depending on the set values at the factory, the engine has more or less power (e.g. 1.9 liters cylinder unit of VW has serial power of 68, 90 or 110 hp). Furthermore the automobile manufacturers set the power to the best possible insurance class in the relevant country as in this way the same automobile is adjusted and sold abroad with different performance data i.e with different engine power.

Can the chip be installed to a new automobile? On principle, yes, because the manufacturers themselves equip and deliver their engines with more greater or lesser power. However it is recommended in the first few weeks to wait with the software pre-programming or with the installation of a chip tuning module, because often in new automobiles when started to be used some small technical defects occur that had not been detected at delivery. Then they could have been falsely related to the modification of the software or the installation of achip tuning module.

Does the maximum speed changes?  In some automobiles the ultimate speed is increased  with approximately 10% (depending on the wind and slope), some software products offer the opportunity to change the maximum speed set in the factory but on principle all settings that are made does not affect the speed limitation set.

Does the operation life of the engines shorten? On principle the operation life of the engine depends on the drivers’ way of driving at the ride itself but this also refers to serially manufactured   automobiles with no chip.

Will the change in power be noticed?  Yes, most of all increasing the torque value is noticed at the lower limit – at lower RPM. The more evenly spread power is noticed at the first troy out ride.      The acceleration values are far greater than the serial ones.

Does the fuel consumption increase?  No, in diesel engines a significant reducing of fuel consumption is noticed while in petrol engines it stays unchanged.

How does higher power and at the same time lower fuel consumption is achieved?  The engine has more power and torque, reaches the higher gears quicker and the ride on a higher gear is longer during the trip. The higher gear affords the engine to work at lower RPM. In lower engine RPM there are fewer injection cycles and from there lesser quantity of injected fuel.

What are the ways for changing the power and the torque?  There is a number of methods that we use: 1. Standard method, where software reading and recording is possible after dismounting the ( EPROM ) chip; 2. With special hardware, the software can be read from the chip directly through the jack for diagnostics  ( OBDII ), 3. After the dismounting the (ECU), using special hardware an exchange of data with the chip is performed through control points on the very plate. This method is used when it is impossible to dismount the chip or it is set in the microcontroller ( BDM ), 4. In this method an additional module is installed between the ECU and the injection-fuel system that in definite momentums or permanently is involved in controlling the engine ( MODUL ).
