Absolutely. DFlasher includes a factory reset feature that restores your ECU to its original factory state with a single tap. This is ideal for dealer visits or if you sell your vehicle.
Stage 0 (stock with full diagnostics), Stage 1 (safe daily performance tune), Stage 2 (aggressive performance with supporting mods recommended), and Custom (upload your own maps from a tuner).

Aftermarket ECU tuning can affect warranty coverage. However, DFlasher's factory reset feature allows you to return to your stock calibration before dealer visits. Consult your warranty terms for specifics. Contact our support team if you have questions.
DFlasher is available on both iOS (App Store) and Android (Google Play). Your phone needs Bluetooth 4.0 or higher. Most smartphones manufactured after 2015 are compatible.
