Chiptuning

Together with the development of control units that control combustion process and fuel metering, etc., there is a relatively new field of flowering in the field of tuning adjustments and it is chip tuning. Specialist firms can use simple serial data modifications such as control units improve engine performance or alter its course of torque.

The word originated Greenhouse composition of English words chip (integrated circuit with the ability to quickly process and store information) and tuning (tuning, adjustment).

History:

When in 1979 began series BMW car mounted the first electronically controlled ignition Bosch Motronic in the BMW 732i, also began to write the history of chip tuning. Electronic Control Unit ( ECU ) functions merged previously separate control units for dispensing fuel, ignition, etc. and the first control programs stored in the memory controller. Diesel engines enjoy an early controllers a few years later, in 1986, and again fell to the primacy of the BMW automobile.

The first control unit was equipped with a microcomputer with EPROM memory with a capacity of only 4 KB and master control unit, only a few functions. For comparison, today's controllers have a memory capacity of over 1 megabyte (1000 KB).

What is chip tuning?

If the vehicle is equipped with onboard diagnostics OBD II or EOBD software modification can be performed without mechanical intervention. With cable diagnostic socket will modify the software in memory controller. There is no exchange or substitution of the software, the software in the control unit modifies only. This modification can increase the performance of turbocharged engines by about 25-35%, at atmospheric engine with power increased by an average of 8-12%.

The original data controllers are usually carefully backed up. This allows the control unit in case of interest to return to its original state.
