Technology

If you own a diesel car, van, SUV, or truck, you probably desire more power and better overall performance. In recent years, many improvements have been made to the once noisy and sluggish diesel engine. Despite the latest technology that has produced a quieter ride and cleaner emissions, diesel engines still lack the power and responsiveness of their gasoline counterparts.  If you are like many diesel owners who are seeking a practical and high-quality tuning device, TDC Technologies has the answer - the PowerBox.

The PowerBox is an adjustable plug-in power conversion that provides up to 30% more horsepower (HP/bhp) and torque.  Power gains vary depending on the type of engine and fuel injection system used. The unit is digital and consists of a microprocessor housed in a shock resistant casing. The unit can be installed in less than 5 minutes. All TDC Technologiesí PowerBoxes are equipped with OEM plugs that are inserted into the wiring loom between the fuel injection system and the Electronic Control Unit (ECU). The PowerBox intercepts the signals that pass back and forth, and modifies them to create an increase in fueling by altering the timing of the injectors, holding them open longer.

A larger amount of fuel injected into a diesel engine creates a significant increase in power and improves overall performance. Unlike the gasoline engine that provides airflow proportionate to acceleration, the diesel engine runs with an excess air flow most of the time, causing it to run well below its maximum combustion capacity. This means that optimal combustion can still be achieved despite the increased fuel injection produced by the PowerBox.

 

Increased Efficiency Means Increased Fuel Economy

It may seem ironic that increased fuel injection can lead to improved fuel economy, but that's exactly what happens under certain conditions. This is possible due to the increased torque, which enables the engine to operate in higher gears at lower speeds. By adjusting the PowerBox to achieve a modest improvement in power/torque, slightly more fuel is used. However, the fuel consumption required to increase torque is offset by an increase in fuel economy due to better operating efficiency in that range. Of course, someone with a radical driving style would see no improvement in fuel economy.

 

Reliability and Safety

The PowerBox will not change the service intervals or reduce the life of your engine. The performance enhancement offered by all of our units takes into account the safe mechanical limits of your engine. Remember, only the parameters of the injection timing are altered, while pressure and fuel/air ratios controlled by the ECU remain unchanged. The result is smooth and responsive acceleration that produces sportier handling, without increased emissions.
