Fleet Efficiency Programme
Individually calibrated economy remaps for working vehicle pools, fitted at your depot or yard.
Cut fuel spend across your fleet
Running multiple vehicles? Fleet economy remapping is one of the most cost-effective things you can do to reduce fuel spend across a working vehicle pool.
Every vehicle in your fleet gets its own custom-written calibration rather than a one-size-fits-all file — because a Transit Custom does different work to a Sprinter, and both deserve a map that reflects that.
I work directly with the fleet manager, come to your depot or yard, and can turn vehicles around one at a time to minimise operational disruption.

Built around your operation
Minimal disruption to vehicles that need to keep working.
One map per vehicle
Each vehicle gets its own custom-written calibration, not a one-size-fits-all file.
At your depot or yard
I come to you, so vehicles never leave site.
One vehicle at a time
Vehicles turned around one at a time to minimise operational disruption.
No mechanical changes
This is a software-only calibration. Nothing is physically fitted, removed, or altered on the vehicle.
Fleet tuning FAQs
Yes. An economy remap adjusts settings like fuel mapping and injection timing so the engine runs more efficiently. Real-world results vary with driving style and vehicle, but a 5–15% improvement in fuel consumption is a realistic, honest expectation — not a guaranteed figure.
No. It's a software-only calibration change to your ECU — no physical parts are fitted or removed, and it can be reversed back to the factory file at any time.
Yes — a 30-day guarantee, underwritten by me. It covers problems with the calibration file itself: if something isn't right with the map and it can't be resolved, I'll restore your original file and refund the cost of the work. VIEZU's technical support sits behind me on file issues, so problems get fixed properly rather than argued about. To be clear, it's a guarantee against a faulty file — not a guarantee of a specific MPG figure, since real-world economy depends heavily on how and where you drive.
Potentially, yes — most manufacturer warranties can be affected by a remap, as it's classed as a modification. If your vehicle is still under manufacturer warranty, I'll talk you through the risk honestly before going ahead. For peace of mind, I keep a backup of your original factory map and can restore it at any time, for example before a warranty repair or dealer visit.
