CHIPTUNING

Most engines in modern cars are controlled by an electronic control unit (ECU). This will continuously adjust the amount of fuel injected, turbine pressure, ignition timing, etc.

Ecotuning optimizes the engine management program based on many parameters (measured values). The chips in the ECU contain software and these programs are usually well written within the maximum load range of the particular car engine. Therefore, this space offers the possibility of Ecotuning for car engines without causing irreparable damage to the engine. This optimization can save up to 20% fuel. This differs per vehicle type. Your vehicle warranty is also maintained by Chiptuning or Ecotuning from Chip Performance.

The principle of EGR is that a certain amount of exhaust gas from the engine is returned to the combustion chamber through the intake manifold. The exhaust gas mixes with the incoming air, reducing the oxygen content in the combustion mixture. Therefore, more inert gas is introduced into the combustion chamber.

In gasoline engines used in the automotive sector, exhaust gas recirculation is controlled by the EGR valve. The valve is located between the exhaust manifold and the intake manifold. In early systems, the valve was operated by the differential pressure in the intake manifold.
The mechanical action is adjusted in such a way that the valve only opens at partial load. In more modern systems, this is mainly done with the help of electric valves, so that better control can be achieved.

Chip Performance Chiptuning is your partner for DSG tuning. Your DSG is controlled by a separate electronic computer that communicates with your engine's ECU. This computer has a standard program that ensures that the gearbox shifts based on factors such as your accelerator pedal position and engine load. Do you want to reprogram this computer? Then discover our service about DSG tuning.

A common problem with DSG/S-Tronic transmissions are early shift points, late downshifts and/or slow gearbox response time. We can customize your gearbox by rewriting the software to your liking. However, from the adjustment of the second stage (or above 400Nm) the gearbox software must be adjusted because the torque limiter and shift pressure must be adjusted.

Chip Performance Chiptuning recently purchased a Dynorace 4WD HLS. The dynamometer can measure power up to 1200 hp or more. The roller dynamometer is suitable for 2WD and 4WD vehicles.

Due to the HLS system, Dynorace is the only dynamometer that can choose to connect and separate the front and rear axles.

The hydraulic connection ensures that the front and rear axles reach the same speed. Using the HLS system, 2WD vehicles with ABS, ESP and anti-slip adjustment can also be tested without any problems.

Today, most cars and commercial vehicles are equipped with Diesel Particulate Filters (DPF). The purpose of this is to allow exhaust gas to pass through and to collect soot particles. This is of course good for the environment, but certainly has disadvantages for the engine.

The soot particles are temporarily stored in the soot filter (DPF). Because the filter is saturated, a regeneration process takes place every few hours. This is measured by the pressure sensor in the diesel particulate filter (DPF). During this process, soot particles burn at high temperatures. Therefore, a large amount of diesel must be injected into the diesel particulate filter (DPF).

The NOX sensor has two chambers. In the first chamber, the oxygen content in the exhaust gas is kept at about 10 ppm by a so-called pump flow. The current required for this is inversely proportional to the air-fuel ratio and can be used to correct the NOX signal based on the measured air-fuel ratio.

The NOX reaction takes place in the second chamber. The current required to keep the environment around the platinum-rhodium electrode oxygen-free is proportional to the NOx concentration and thus provides a measurement signal
