Engine tuning

Professional mobile ECU remapping

An ECU remap changes the software controlling the engine. Done properly, it can improve torque, throttle response and usable performance while keeping factory protection strategies in place.

What we change — and why

Factory software has to cover different markets, fuel grades and model positions. A vehicle-specific remap can refine boost, fuelling, ignition and torque requests within sensible limits. The result should feel stronger and more responsive without becoming difficult to drive.

All software is calibrated in-house by experienced engineers, so each remap is tailored to the vehicle and what you want from it: smoother power delivery, sharper throttle response and a noticeable improvement in everyday driving.

What's included with our ECU remapping

Custom ECU calibration tailored to your vehicle
Improved power delivery and throttle response
Increased torque and overall drivability
Diagnostics carried out before and after tuning
Fully mobile service at your home or workplace
Lifetime software warranty and lifetime support
14-day money-back guarantee

Stage 1: an efficient performance boost

Stage 1 optimises an otherwise standard, healthy vehicle with no hardware upgrades needed. We refine parameters such as ignition timing, fuel delivery and boost pressure to release extra performance while keeping reliability first.

Options such as DPF, EGR and AdBlue solutions, speed limiter removal and burble activation can be added where supported.

More horsepower and torque
Sharper throttle response
Smoother power delivery across the rev range
Better everyday drivability

Stage 2: for modified vehicles

Stage 2 builds on Stage 1 for vehicles with supporting hardware such as high-flow induction kits, performance exhaust systems or freer-breathing components. Because the engine can breathe more freely, the calibration can safely make more of it.

Higher peak horsepower and torque
Improved mid-range and top-end performance
Consistent power delivery across the rev range

Insurance and servicing

A remap is a vehicle modification and should be declared to your insurer. We provide clear information about the work carried out so you can describe it accurately. Routine servicing remains essential; tuning is not a substitute for maintenance.

Common questions

Is ECU remapping safe?

Yes. Every remap is developed with reliability as the priority, and every vehicle is checked with dealer-level diagnostics before and after tuning to make sure everything is operating correctly.

Will ECU remapping affect my warranty?

ECU remapping can affect a manufacturer warranty. We are always happy to talk this through beforehand so you can make an informed decision.

How long does a mobile ECU remap take?

Most mobile ECU remaps take between one and two hours, depending on the vehicle and ECU type.

Can ECU remapping improve fuel economy?

In many cases, the extra torque and improved engine efficiency can lead to better fuel economy when the vehicle is driven sensibly.

Do you offer a warranty on ECU remapping?

Yes. All ECU software installed by MTechTuning is covered by a lifetime software warranty, with lifetime support and a 14-day money-back guarantee.
