Oxford Tuning & Remapping | VIEZU

The term “remapping” refers to the change of software within the electronic control unit (ECU) of a vehicle. Increasing the vehicle’s performance, economy, and/or fuel efficiency is possible by modifying the operating parameters within the code (or “map”).

Often, the onboard diagnostics port (OBD) provides access to the map contained within the ECU. Some newer models require the ECU to be removed before a bench modification can be carried out, which takes us a bit longer.

Following an evaluation of the ECU by an IMI professional certified engineer, the file writing team will adjust the original calibration to maximize performance, fuel economy, or a clever blend of both.

Remaps are custom-made, so we can adjust not only the performance and economy, but also fault codes, DPFs, EGRs, and removal of speed limiters.

It normally takes less than an hour to replace the ECU in a vehicle, depending on the vehicle and type of ECU.

We offer 30-day money back guarantees on all of our remaps. In the unlikely event that you are not satisfied with any aspect of your car’s performance, bring it back to us and we will return it to its original parameters and give you a full refund.
