Fleet Remapping


MTech Tuning also specializes in Fleet Remapping.

Our technicians visit your location, connect their computers to your trucks' diagnostic ports, and install custom software designed to modify your truck's ECU response to engine sensor inputs. This process allows us to adjust torque curves, optimize air-fuel ratios, and fine-tune injection timing, resulting in enhanced fuel efficiency (MPG), increased torque at lower rev ranges, and improved throttle response for smoother acceleration.

For most HGV makes and models, a well-crafted remap can yield 10-20% more horsepower, improved low-end tractability, increased torque, and enhanced fuel economy. Actual results may vary based on your specific model and engine details.

Remapping for Fleets or Individual Trucks – Our Service is Flexible.

For optimal improvements tailored to each HGV or fleet vehicle, our remaps are meticulously hand-coded for specific make, model, and engine. We can also customize maps to suit individual driver preferences.


If your team faces challenges like tractability, torque, acceleration, or handling issues, we can adjust map parameters to address their concerns and enhance the driving experience.


Our service is streamlined and efficient. An MTech Tuning technician can visit your location, connect to your trucks' diagnostic port, and start coding a map within minutes. This allows us to remap multiple HGV makes and models in a single afternoon, making it ideal for fleet operators managing diverse trucks.


Our quick and reliable service is equally suitable for owner-drivers seeking significant performance upgrades for a single HGV. Our hand-written maps fine-tune performance without compromising reliability or engine lifespan.

How it Works!

Modern truck engines rely on a complex sensor network, measuring factors from camshaft speed to fuel pressure and injection timing. These sensors transmit data to the ECU, which utilizes lookup tables or 'maps' to make adjustments based on changing conditions.


Ideally, default maps would optimize fuel efficiency, torque, and power. However, manufacturers must consider diverse real-world conditions, leading to compromises in default maps due to factors like air pressure, temperature, fuel quality, emissions regulations, and servicing infrastructure.


With MTech Tuning it's possible to enhance your vehicles performance by adjusting the data in these maps. Our in-house team of skilled technicians has the expertise to remap your ECU, tailoring it to your engine's capabilities for improved fuel efficiency and overall drivability.
