What is chip tuning?

What is chip tuning?
Penetration of injected totally changed internal combustion engines. For a more precise operation of the engines have their e-regulation. This regulation is carried out through various electronic sensors of the so-called engine computer (ECU). It hosts the processor that controls all processes and memory which is stored in software management. The very name "chip tuning" in translation means setting the software in memory. By modifying the software that can achieve improvements in power and engine torque, and elimination of various restrictions, factory-set (maximum speed, etc.)..
What can be expected from chip tuning?
For atmospheric engines - increase power and torque to 10%. For turbocharged engines - up to 30%. Besides more power and acceleration through chip tuning is possible and eliminate various types of electronic limiters (eg speed limiter - most 250 km, speed limiter, etc.).. After increasing chip tuning and sensitivity "to the engine throttle. By chip tuning to achieve lower fuel consumption due to improved torque at low engine speeds.
Are changes to the engine?
Optimizing software engine control unit (ECU), requires no other changes to the car. Changing the optimized software is done in three ways depending on the model of ECU-it:
Are changes to the engine?
1. Hardware replacement of memory in the ECU-it

2. Reprogramming of the memory in the console diagnostic (OBD Tuning)

3. Reprogramming the software in the ECU-direct it if it is not possible replacement of hardware support. (BDM tuning).
