Frequently asked questions
How does a remap with the REPROG pack work?
You install the MyFlasher app (iOS or Android), plug the REPROG by Dynaparts Bluetooth OBD dongle into the OBD port with the battery on a charger, and start the read: your ECU's original map is sent to us. You request your map in the Chat tab; our workshop prepares it from this file, then you write it from the app in a few minutes, without removing anything.
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 well-maintained stock vehicle: they may vary with engine condition, fuel and measuring conditions. A remap changes the vehicle's characteristics: remember to inform your insurer.
