What is Chiptuning?

Chiptuning - electronic tuning of a motor controller.

It aims to improve the engine parameters by changing the driver software itself (ready-made software, simpler, cheaper, and more risky tuning, widely available) or by using program changes on the basis of optimizing the engine's operation by adjusting its relevant content based on a precise measuring range. This is a chip tuning option that gives high security, high quality, and the best possible results.

Tailor-made chiptuning consists of making individual program adjustments or by an external controller. This best chip tuning option is preceded by precise load diagnostics, condition verification, and individual reserves of a given item. This chiptuning is based on a series of measurements in a dynamometer, road conditions, and tuner's extensive experience. The characteristic curves, maps, and limiters contained in the program are modified in terms of improving = increasing the power and torque of the engine, but the priority is to obtain optimal and safe parameters of its operation. By editing the program, you can change values ​​such as:

- max speed
- engine revolutions
- boost
- fuel dose
- ignition angle
- moment of the start of pressing
- injection time
- mix composition
- torque characteristics
- and many others (practically everything controlled by the engine controller)

The manufacturers of combustion engines leave a certain reserve of power and torque in both its mechanical design and control, e.g. through software. It aims to ensure the universal operation of the drive unit regardless of its operating conditions. Safe increases for "naturally aspirated" engines are approx. 15-40% of the original power (often mechanical changes are required to obtain increases higher than 7%, e.g. change of the air intake), for engines, "charged" from 15%, and even up to 60% of the nominal power.

Chiptuning also allows for savings on fuel. However, made in a responsible manner. not professional, without condition verification by chiptuning, without a precise measuring range, without power measurements can often result in a significant shortening of service life and not achieving the desired effects. On the other hand, tailor-made chiptuning is characterized by obtaining a safe way to improve power, torque, and fuel savings in an optimal and safe way for a given copy. In addition, it allows you to maintain life and even extend it.

ECU - Engine Control Unit

An electronic device managing operation of the internal combustion engine.

It can cooperate with such sensors as lambda probe, shaft position sensor, camshaft position sensor, vacuum sensor, flow meter, coolant temperature sensor, intake manifold temperature sensor. Based on the information collected from these sensors, and data saved in the memory, the controller computer selects the appropriate proportions of fuel and air in the mixture and determines the moment of fuel injection into the cylinder, determine the moment of ignition(advance angle) of the mixture in spark-ignition engines.

Electronic injection engines use less fuel than comparable carburetor engines. The first electronic control of engine power supply was installed in cars in the early 80s. The engine with electronic injection is also safer in operation - the computer does not allow high shaft revolutions and automatically cuts off the fuel injection at given revolutions. The ECU controller also automatically selects the right fuel dose at low temperatures, which eliminates the need for the choke to start the engine.
