Reviews & Frequently Asked Questions

Why Choose LNR Performance

At LNR Performance, we specialise in custom ECU remapping, dyno tuning, and in-house calibration. Every file is custom-built and tested on our dyno to ensure optimal performance, reliability, and drivability. Below you’ll find answers to the most common questions about our services, tools, and vehicles we work with.

  • What is ECU remapping?

    ECU remapping is the process of fine-tuning your vehicle’s engine control software to unlock better performance, torque, and efficiency. LNR Performance develops and calibrates all remaps in-house for precise, safe gains.

  • Do you create custom maps or use generic files?

    Every map is written and tested on our own AWD Linked Bapro dyno using your vehicle’s data. We never use "off-the-shelf files". All tuning is bespoke to your car.

  • Is remapping safe for my engine?

    Yes. Our calibrations are thoroughly tested and stay within safe limits for your engine and drivetrain. Reliability is always our top priority.

  • How long does a remap take?

    Most remaps take around 1–2 hours, though will take longer if it includes dyno runs etc.

  • Can you return my vehicle to stock?

    Absolutely! We keep a secure backup of your original ECU file and can restore it anytime.

  • Will a remap void my warranty?

    Any modification can effect a manufacturer warranty if detected. We offer safe, conservative calibrations and can restore the vehicle to stock if required.


  • Do you tune Automatic & DSG/TCU gearbox?

    Yes, in many cases we can tune the transmission (TCU) for faster shift times, unlock torque limitation and create an overall better driveability. Availabilty depends on the vehicle and ECU/TCU type, get in touch and we can let you know.

  • Do you offer pops & Bangs / crackle maps?

    Yes, though we only recommend this feature be enabled if the hardware can handle the modification and it won't damage components such as the GPF/OPF or catalytic converters, we will advise you on this should you choose to have it done. 

  • Do you sell tuning tools?

    Yes! We’re authorised suppliers for Autotuner and KESS3 and can advise workshops or tuners on the best setup for their needs.

  • Which tuning tools do you use?

    We use industry leading equipment including Autotuner and Alientech KESS3 for safe, accurate ECU and TCU calibration.

    Yes, LNR are TASSA Certified and qualified installers of Ghost Autowatch, Scorpion and Trackstar Trackers.We supply and fit at both of our locations in London. Go to our Alarm & Tracker page to book your Installation.

  • Do I need supporting Modifications?

    A stage 1 normally requires no hardware changes. If you are looking to push your vehicle further, you will need supporting hardware in order to achieve this. Get in touch with us for more information 

  • Can you diagnose issues before tuning?

    Yes, we perform a pre-tune health check including full diagnostic scan, boost leak inpsection and data logging. We will not tune a vehicle that isn't mechanically sound.

  • What happens during a dyno session?

    We run the car under controlled conditions, record baseline figures then calibrate the map data and perform multiple verification runs. You'll also receive before/after printouts  (logs) from the dyno.

Called these guys with some questions about my fiesta ST as I have never had a car mapped.


Turned out to be a great idea. These guys talked me through the process and helped me pick the sort of map I wanted.


Would 100% recommend to anyone! My dad is booked in with them now for his car!
