Modern cars heavily depend on electronics. Many of the components in a vehicle will now be managed and monitored by so called Electronic Control Units (ECU). Typically, there are now ECUs for the gearbox and for the engine management. The ECU for the engine management will be programmed to meet specific requirements. For example, it will prevent high fuel consumption by translating a full throttle when accelerating into a gradual increase in fuel supply.
Tuning companies make use of the ECU and the ability to re-program them. This process is called ECU remapping (also known as ECU tuning or chip tuning). It involves modifying a car's Engine Control Unit (ECU) to optimize engine performance. This can affect the fuel efficiency and driving experience. The most common, potential benefits are increased power, torque, and throttle response.
The exact outcome depends on the approach a tuner will take or what the driver is aiming for. The car’s manufacturer will set ECU parameters to ensure reliability and compliance with regulations, but these settings can be customized. German Motors has been working with providers of engine tuning kits and our consultants will be able to give an overview of what options there are for your car.
While chip tuning offers the ability to enhance the performance and to improve the vehicle’s handling according to a driver’s preferences, there are also risks involved with chip tuning. For instance, this practice may void warranties as the ECUs have been manipulated. Another risk is engine damage: amended settings may be detrimental to the engine’s health. A word of caution should also be spoken when it comes to DIY chip tuning. The process of adjusting the settings in the ECU is a delicate one and amateurs may accidentally amend parameters to levels that are damaging to the engine. Costly repairs may be the result.
Whether chip tuning is something you should consider or not is not an easy question to address. German Motors will stand ready to assist you on your journey though and if needed, we will assist in any possible way to get your chips tuned.
