No hardware modifications are required; tune add-ons to accommodate hardware changes can be purchased.

It is important to note that we do not remove factory readiness monitors or force readiness for any factory-installed components. If you are installing aftermarket hardware that is for off-road use only, please double-check with your state requirements prior to flashing.

• Flashed at home through the OBD port with the TuneZilla FlashZilla Pro and a Windows 10 or 11 laptop running the TuneZilla Portal App.
• Connect the FlashZilla Pro with a USB-A to USB-C cable. USB-C to USB-C cables are not compatible.
• Your tune is linked to your VIN and syncs to the TuneZilla Portal App, usually right away. Read and save your factory ECU file before flashing.
• Clear all fault codes and warning messages before flashing.
• TuneZilla recommends a battery charger for every flash. Turn the ignition on with the engine off, follow the prompts and do not interrupt the flash.

ECU check: the FlashZilla Pro flashes the 2-plug EDC17CP57 ECU. Vans with the 6-plug MD1 ECU cannot be flashed with the FlashZilla Pro. Confirm your ECU before ordering.

SCR / AdBlue: clear the SCR countdown before flashing (the message can stay on screen after an emissions-off flash). If you run an aftermarket exhaust, clear all dash errors first. Unplug the SCR controller after flashing but before starting the vehicle (TuneZilla confirmed). It is under the driver's seat on Sprinters and in the trunk under the spare tire on most other models. Emissions-off tunes also require unplugging the EGR, swirl flap motor, DPF temperature and pressure sensors, and NOx sensors, or you may get rough, smoky cold starts.
