We employ some of the most experienced and talented people in the industry, combined with an enthusiastic and skilled national dealer team, we are one of the leading Remapping and Chiptuning businesses in the UK. We do not change any hardware in your vehicle, we just modify the operating parameters in the ECU’s program or ‘map’. In many cases the map stored on the ECU’s processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. In some newer models the ECU will have to be removed from the vehicle and the casing opened, our technicians will then use specialist tools to read the original map straight from the processing chip. The technician will then upload the original map to our map writing team who will adjust the parameters to maximise the performance, fuel economy or a clever blend of both. Depending on the vehicle and ECU type the chip tuning process can take under an hour and if at any time you wish to return your vehicles ECU to its original default settings, this can be done easily and free of charge as we always keep a copy of the original software as a backup. ## Key features - Increased power and torque - Improved fuel MPG - Custom ECU maps - Global dealer network - No hardware changes - Return to original settings ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/q-tuning/id1176525111/reviews.md ### 5/5 — Awesome app 👌🏻 *2017-09-01, version 1.0* Great app ### 5/5 — Excellent :) *2017-09-01, version 1.0* Easy to navigate, impressed with speed of app.. bravo :) ## Frequently asked questions about Q ### What does Q-Tuning do for my vehicle?
