The Supernaut TD5 Switchable Dual Map package lets you switch between two custom tunes on your TD5 with a simple flick of a switch.

The maps are your call - choose from our off the shelf maps from Stage 1 through to Stage 2+, along with your choice of hardcut limiter. We can also change the idle speed of each map so you get an audible confirmation you've changed map.

You also have a choice of switch, from an OEM style switch which will blend seamlessly into your dash, or something bespoke (see our Defender pictured with a red dual map switch along side our proprietary cruise control system).

Our work has been proven on our own and customers vehicles over many thousands of accumulated miles, through structured development trials, customer feedback and testing and validation, where performance figures, drivability, and long-term reliability are all optimised as part of the development process.

Our own TD5s run a dual map system featuring stage 2 and stage 2+ switchable maps, both of which have more than enough power for our applications.

Mobile Delivery: We generally from the South West to the North Midlands. Please contact us with any questions about mobile delivery before ordering.

Note: If you are unsure if you have a NNN ECU please refer to your engine number. This will start with 15p for NNN ECUs. As a guide, NNN ECUs came in around 2002. If in doubt give us a shout. Mapping for older MSB ECUs is coming soon.
