What we do
Let Us Restore Your Vehicle's Performance IN 3 STEPS!
Diagnostic & Read ECU
NM TUNING provides custom remapped tuning files. Before proceeding, we run a full diagnostic to check for any major fault codes that could interfere with the ECU writing process.
Original ECU Files
We extract the vehicle’s original ECU (Electronic Control Unit) file using tools such as Autotuner, Kess V3, Flex, and others. For both ECU reading and writing, we always use 100% genuine hardware and software to ensure reliability and safety.
Modify & Write File
Finally, we modify the ECU file and safely write it back to your vehicle, delivering improved performance. We collaborate with a WinOLS authorised reseller and an authorised WinOLS dealer to ensure the highest quality and reliability.

Our engne management light came on while driving to Longleat on holiday so we called Nico and he came to meet us within 10 minutes, and on a Sunday, which was amazing! Ran the diagnostic and then fixed the issue within the hour - so friendly and helpful, we're very grateful to him. We were even able to continue our day out at the safari park 😊 Excellent service, would definitely recommend 👍Posted on Harrison Williams30 June 2025Trustindex verifies that the original source of the review is Google.

Great service by Nico, removed my vans speed limiter and applied a stage one remap. Very happy with the work done, went the extra mile to make sure I was happy with everything. Highly recommended.Posted on Jessica Cullen3 June 2025Trustindex verifies that the original source of the review is Google. I contacted NM tuning &diagnostic to ask that they map my car. I didn’t know much about mapping and went with the advice he gave and has stage 1 done. I was shocked by the power it has given it and also helped the fuel economy. He was a really nice guy and got the job done nice and quickPosted on doug smith27 May 2025Trustindex verifies that the original source of the review is Google. Friendly and knowledgeable fixed the issues I was having within the hour . Highly recommendedPosted on Edward Kirton-Darling10 April 2025Trustindex verifies that the original source of the review is Google. A light came on the dashboard while we were driving back from Bath - it said the car was overheating. A mechanic we stopped at told us it needed an oil change urgently. I called NM when we got home to Frome, and Nico came out first thing the next day - quickly identified that it was a sensor issue, then got the part, and did a full service. Car now running beautifully, and all very conveniently done outside our house, and for a very good price. My only concern with recommending this service to everyone on here is that once everyone knows how good NM is, Nico might be too busy to come fix the car next time it breaks down!Posted on ashley cooper7 April 2025Trustindex verifies that the original source of the review is Google.
