Does remapping void the manufacturer's warranty?

Engine remapping is invisible to most standard dealer diagnostic tools. At King ECU we offer a 5-year software warranty and a free factory restore before any dealer visit if you wish.

Is chiptuning dangerous for my engine?

No, as long as remapping is carried out by professionals. At King ECU we develop custom maps while strictly respecting the manufacturer's mechanical tolerances.

Will I really use less fuel?

Yes, in most cases. Increased low-end torque lets you drive in a higher gear sooner, reducing engine speed and therefore consumption.

How long does the process take?

Our online file modification service is delivered in under 30 minutes after we receive your original ECU file.

Can I return to the original configuration?

Of course. We always keep a backup of your original map on our secure servers. Factory restore is completely free for 5 years.
