Switchable Remapping

Switch between multiple states of tune and stock with ByteFLASH Touch.

We understand one state of tune isn't always suitable for all situations so we launched ByteFLASH. ByteFLASH is a unique handheld switchable remapping programmer that allows the driver to switch between multiple states of tune quickly and easily as often as required. ByteFLASH stores your original 'stock' tune and up to 5 modified states of tune ready to be written to your vehicle at any time.

All switchable remapping software for ByteFLASH is written in-house by our technical team as per your requirements, opening up a world of possibilities. A race map for the track? No problem.. then switch to a high torque at low-rpm map for towing and then back to an economy remap for the daily commute to work? All possible with ByteFLASH switchable remapping.

ByteFLASH Touch will be shipped to you without tuning files. You'll plug the unit into your car and read the stock software from the ECU. Plug the ByteFLASH Touch into your computer via a USB port and send the cars original file to our technical department. We'll then develop multiple states of tune as per your requirements.
