Add the service to your cart, then attach the read from your MED9.1 control unit (original) in the cart and provide the make, model and year of the vehicle. Without a file the cart will not let you proceed to payment, so nothing gets lost along the way. We support .ols, .bin, .hex, .frf, .sgo, .fls formats and ZIP/RAR archives.

We prepare the map so it operates within a safe range – without raising temperatures beyond permissible values. By default we apply a moderate setting; with a very aggressive effect the exhaust system wears out faster, so stronger variants are made only on explicit request.

No. The effect is already audible on the factory exhaust system. With a sport exhaust or after removing the particulate filter the crackles are noticeably louder and sharper.

Orders are usually processed within a few hours on business days. We send the file to the e-mail address given in the order, together with a short note on what to watch for when flashing.

Yes. Simply flash your original file back, which is why you should always keep a backup of your read. We also store your file for the duration of order processing.

For some control units we prepare a version switched on with a button in the car. Check the Pops & Bangs category to see whether such a version is available for MED9.1 – if not, we will tell you what is possible.
