How does the Speedhawk-Tuningboxes function?
This Electronics is used with vehicles, which are equipped with conventional electronic injection pumps of the manufacturers Bosch or Lucas. Here an increase in output takes place via a change of the injection pump signals from the controller to the injection pump.

How does the Speedhawk-Tuningboxes affect the fuel consumption
With equal lasting and/or defensive driving fashion the fuel consumption remains the same or sinks.One "before - afterwards - measurement" with a Mercedes 220 CDI on a test track: a fuel reduction of 1,2 l/100 km in the case of defensive driving fashion and a maximum speed of 140 resulted in 30 km highway, 10 km city travel and 30 km motorway km/h on the motorway

Why less consumption after the tuning?
The torque characteristic of the engine is changed by the Speedhawk-Tuningboxes and substantially more flexibly. Therefore it can be driven in the town traffic with less switch-process. Each shifting process is constant accelerating and deceleration of the masses and costs most fuel. The number of shifting processes, otherwise needed, and thus the fuel consumption are thus reduced = higher torque = smaller number of revolutions = smaller consumption.

Grime my vehicle after installation of the Speedhawk-Tuningboxes?
No. Only badly coordinated vehicles grime

How does the Speedhawk-Tuningboxes affect the finale speed?
The Speedhawk-tuningboxes was developed to the torque increase and optimization in the lower and middle speed area. Nevertheless, it comes with some vehicles for a rise of the final speed. This lies within the range of 5 - 15 km/h and is vehicle dependently.

Why doesn´t the manufacturer adjust the vehicle equivalent optimally?
The manufacturer builds a car for the world-wide market. In other countries the fuel often does not correspond to our German quality standard. Also the continuous operation by extreme heights can make worse the combustion. Indeed, are of these qualities which must not be taken into consideration within Europe. Besides the manufacturing tolerance can also play a role. If the vehicle after the production on the test bench stands the achievement must be raised perhaps something else. Tolerance is necessary for it.
