BT Group, one of the UK’s largest fleets, is set for a series of major environmental, performance and financial improvements following a partnership with Bromsgrove vehicle tuning and ECU remapping specialist Viezu Technologies.

The programme, which began in late August, will see more than 20,000 of BT’s light commercial vehicles remapped using Viezu’s proprietary technology, to deliver better fuel consumption and reduced CO2 emissions, while also improving vehicle driveability.

“BT is committed to being a responsible and sustainable business leader, so remapping our vehicles for economy and better environmental performance makes complete sense,” said Steve Watson, senior innovation and design specialist, BT Fleet.

“But it’s not just these benefits which make it appealing. Once we saw what was technically possible, we crunched the numbers and the business case also stacked up.”

The vehicles being tuned within the upgrade programme range from small Corsa-sized vans through to larger Transit chassis-cab vans, with much larger payloads and different driving cycles.

Viezu, on Aston Fields Industrial Estate, and BT Fleet have developed a blend of tuning solutions to match BT’s requirements, including throttle, rev, speed and power limiting. It is anticipated the programme will help BT deliver savings of over £3 million.

“Vehicle remapping offers fleets a host of opportunities and we’re being increasingly asked by companies like BT to help them achieve their own environmental and cost reduction targets,” said Paul Busby, chief executive, Viezu Technologies.

“With an ISO-certified process and a potential payback period of just three months, any technical risks are minimised and rewards can be felt almost instantaneously.”

The remapping programme for BT’s 24,000 vehicles is set to be completed within four months and more than 5,000 vehicles have already been converted.
