The PedalBox was developed in order to improve response in modern cars. The PedalBox is an additional control unit, with four user-selectable programmes, that increases throttle response by removing delays in the accelerator, enhancing driveability.
Explanation: The “Throttle Response” curve shows the speed at which an engine responds to the driver’s pressing of the accelerator. Deficiencies are evident here, especially at times of strong acceleration. Throttle response has less to do with how much power a vehicle has but rather how long it needs to fully release this power, with petrol engines frequently performing better here than diesel ones in this regard. Usually, a naturally aspirated engine is more powerful than a compressor or a turbocharger, a fact which is however not often noticed as the cars are given different response times by the manufacturer. But even when the same engine types are compared, ultimately a difference in response will be determined, as there are a wide range of factors that influence the response of an engine. The throttle response of a stick-shift or a semi-automatic car can be easily enhanced simply by changing gears – in the case of a small car trying to overtake another car for instance, by moving from 5th to 4th gear. Most vehicles are equipped with a drive-by-wire system. Here, acceleration is achieved by way of an electric signal and not by the familiar Bowden cable, something that most people are not aware of. This system is called ETC or ECM. The problem is that these systems often suffer from a significant signal delay, which the PedalBox can compensate for perfectly. This means that more energy is available to the car once again.
The PedalBox is located between the accelerator pedal sensor and the control module and works by capturing the accelerator pedal signal and transforms it. Lots of manufacturers offer similar functions via standard “sports buttons”. The PedalBox reduces the pedal travel necessary in order to reach a “throttle wide open” state (full throttle response). This allows the driver to exploit the full potential of the engines.
Greater control. User-Adjustable.
All drivers face a wide range of driving conditions and situations. The PealBox allows drivers to choose between four levels, each with three seperate modes offering improved response. The PedalBox includes different programmes tailored to meet the most drivers range of driver’s wishes. The driver can select the programme most suited to the driving situation.
Reduced response time. More dynamic.
Moments of delay are a thing of the past. The signal is immediately followed by the response, giving the driver the feeling that he or she is accelerating faster. However, the torque remains the same. It is merely the response ratios that have improved.
Maximum efficiency. Greater driving pleasure.
Once responsiveness has improved, driving is a lot more fun. Plus, quick acceleration without any delay gives drivers the feeling of being in better control of their vehicle.
Practical and beneficial.
Modifying the values set by the manufacturer therefore has advantages. The PedalBox will meet the expectations of customers and their cars. The often delayed throttle response of modern engines is gone, while retaining the standard engine control unit.
