  • What is the difference between the Doho Flasher and other tuning methods?

    Other tuning methods, such as chip tuning boxes or pedal boxes, require the installation of visible, physical devices to bring about changes. The Doho Flasher, on the other hand, allows you to directly access the control software of your vehicle. As a result, it is more efficient without vulnerable intermediate steps.

  • Can I tune my vehicle myself with the Doho Flasher?

    Yes, with the Doho Flasher, you can easily and safely tune your vehicle yourself. Take a look at our guide on doho-flasher.com for more information.


  • What is the difference between the original and modified software versions?

    The original software version is the control software of the vehicle as intended by the manufacturer. The modified software version is the customized version of the control software that improves the engine’s performance within reasonable tolerance limits.

  • Can I switch between the original and modified software versions?

    Yes. For example with the Doho Flasher, you can switch between the original and modified software versions at any time. In this case, a backup copy of your original software version is stored directly on your Doho Flasher, as well as in our system.

  • What do Stage 1, Stage 2, and Stage 3 tuning mean?

    The stages in chip tuning refer to the extent of modifications made to the vehicle. Stage 1 usually involves software optimization without hardware changes, Stage 2 requires some additional hardware upgrades (such as a sports air filter or exhaust system), and Stage 3 goes even further and can involve extensive modifications to the engine, drivetrain, and more.

  • Is tuning / chiptuning generally detectable?

    Generally, chiptuning is detectable as it involves changes to the vehicle’s software stored in the control unit. There are various ways in which chiptuning can be detected. The extent of detectability also depends on the type of tuning.
