Frequently Asked Questions


How do the Speedhawk tuning modules work?

Our tuning Modules work by intelligently changing the signal from the injection systems to the ECU depending on the loads and conditions of the engine at any point in time. This change of signal causes the ECU system to adjust various areas of the engine parameters to make it more efficient. This in turn improves the power, torque and fuel economy of the engine.

It is the accurate and superior tuning map settings that determine how much increase in power should be applied at any time, resulting in the most powerful yet smooth driving experience.

Which vehicles can be fitted out with the Speedhawk diesel tuning module?

We supply tuning boxes for most modern cars with either Common Rail or Pumpe Duse injection systems. To see if there is a Speedhawk tuning box available for your car, use our 'Find The tuning Box for My Vehicle' tool at the top of the page.

Can our tuning module damage my engine?

No, the tuning module cannot put the vehicle outside its manufacturers limitations govern by the ECU.

Does the vehicle have a shorter lifetime after modification?

No, Speedhawk tuning modules only cause the ECU to adjust the systems within the manuafactures known tolerances of the engine. If there is an existing fault within the engine at the time of installation, having the tuning box fitted may highlight it.
