ByteFLASH Touch

ByteFLASH Touch allows the installation of ByteFLASH Automotive Software quickly and easily at home, without the need to visit one of our installers, in six easy to follow steps!

1. Backup your vehicles current software calibration

ByteFLASH Touch will prompt you to read a backup from the vehicle the first time it is plugged in.

2. Download the ByteFLASH software to your PC

Install the ByteFLASH software onto your PC and connect ByteFLASH via the supplied USB cable.

3. Send your backup to the ByteFLASH technical team

Open the ByteFLASH software and copy the backup to your PC. Attach this to an email along with your tuning requirements.

4. Upload your modified software to ByteFLASH Touch

Once your modified file has been returned to you via email, use the ByteFLASH software to copy this onto the ByteFLASH Touch handheld programmer.

5. Upload the software to your vehicle.

Plug ByteFLASH into your vehicles diagnostic socket, and select which modified file you would like to upload to the vehicle.

6. Drive your vehicle, and enjoy the benefits of ByteFLASH!

Individually tailored to each specific customers requirements, ByteFLASH Automotive Software will have transformed the way your vehicle drives.

  • What if I don't have a PC?
  • Can my vehicle be returned to standard in the future?
  • Will ByteFLASH software effect my fuel economy?
  • Will the life span of my engine be reduced?
If you don't have a PC or are not confident installing the ByteFLASH software then you have a number of options. Either plug ByteFLASH Touch into your vehicle to perform the backup, and post the device back to us. We'll install your vehicles modified software onto ByteFLASH Touch and return the device to you at no additional cost! Alternatively you can visit one of our installers to have ByteFLASH software installed directly onto your vehicle.
Of course! If you're using one of our ByteFLASH Touch OBD programmers you can switch between stock and tuned as often as required, quickly and easily yourself. If you had ByteFLASH software installed by a ByteFLASH installer your original software will be stored both with the installer and us. You would be able to visit any ByteFLASH outlet to have your vehicle returned to standard.
In most cases the fuel efficiency of the vehicle remains unchanged in like for like driving conditions over the combined cycle. If you're looking to improve the fuel efficiency of your vehicle then our economy tuning software will meet your requirements whilst still giving performance and drivability improvements. Drop us an email or call us on +44 (0)1622 320496 and we can run you through the options available for your specific vehicle.
Well developed tuning software will not reduce the life span of your engine. All of our software is designed to work safely on a standard vehicle and within the capabilities of factory components. Of course we do see a lot of badly developed engine software in the market, which can and does harm engines. We urge customers to choose high quality software such as ByteFLASH.
