Frequently asked questions
How does a remap with the REPROG pack work?
You plug the REPROG by Dynaparts Bluetooth OBD dongle into the vehicle's OBD port and install the MyFlasher app (iOS or Android). The dongle reads and saves the stock map, then loads the Dynaparts map for your engine. Flashing takes a few minutes, with no dismantling.
Why give my vehicle's VIN?
The map is prepared for your engine and ECU. The VIN (field E of the registration document) lets us check the exact vehicle version before shipping.
Can I go back to the stock map?
Yes. The stock map is saved during the first read and can be restored at any time from the app, in a few minutes.
What is the difference between Stage 1 and the E85 pack?
Stage 1 optimises injection, ignition and boost management on the original fuel. The E85 pack installs a FlexFuel map to run on E85 bioethanol, cheaper at the pump, without an add-on box.
Are the stated gains guaranteed?
Indicative figures measured on a stock vehicle in good maintenance condition: they may vary depending on engine condition, fuel and measurement conditions. ECU tuning changes the vehicle's specifications: remember to inform your insurer.
