Fleet services

What we can do for a fleet

Fuel economy tuning

Economy software for each engine, usually worth 5 to 15 percent better mpg on diesels driven the same way.

Speed and rev limiting

Speed limiters fitted or adjusted, plus rev, throttle and torque limits to protect vehicles and drivers.

Power where you need it

Performance tuning for power take-off on HGVs and plant equipment.

The fleet approach

Planned around your vehicles

We profile the vehicles you run, taking account of each one's warranty period and de-fleet date, then recalibrate the ECU to suit how they're used.

Fuel savings work best alongside driver training, journey planning and tracking, and we're happy to work with whoever runs those for you.

  2. Free trialWe offer a free fuel economy trial on a few vehicles, so you can see the results on your own fleet first.
  3. Roll outWe tune the rest and keep records, so new vehicles get the same software as they join.

Questions

Common questions

How big does a fleet need to be?

We work with fleets from 5 vehicles upwards, and with single vehicles too.

Will it affect the vehicle warranty?

We look at each vehicle's warranty period and de-fleet date before we suggest anything, and talk you through the options.

Can you fit speed limiters?

Yes. We can fit, adjust or remove speed limiters, and set rev, throttle and torque limits.
