The emissions cutting capability of Viezu’s BlueOptimize remapping service has been confirmed by tests carried out at a VCA approved facility, it says.

BlueOptimize was tested on a standard 2013 Ford Transit 2.2 tdci to the New European Drive Cycle test (NEDC). Analysis of the results showed that as a consequence of Viezu’s engine remapping, the vehicle’s Nitrogen Oxides (NOx) output was cut by more than 17%.

Furthermore, the van’s fuel consumption was also improved, meaning the total amount of fuel burnt, and therefore overall emissions, was also lowered, says Viezu.

“With recent concerns about emission levels, it was important that our fleet customers could have the added confidence about BlueOptimize’s air quality credentials brought about by certified independent testing,” explained Linda Busby, managing director, Viezu Technologies.

“These results prove this to be the case and show that fleets can clean up their emissions while also saving fuel and even improving vehicle driveability at the same time.”

Its BlueOptimize service was launched in 2012 and since then more than 250,000 vehicles including some of the largest fleets on UK roads have had their emission levels and fuel consumption improved with the service.

Viezu’s team of in-house software engineers develop bespoke engine maps for every vehicle, taking into account the vehicle’s typical drive cycle, load and other key characteristics.

The engine map is then modified to introduce factors such as rev or throttle limiting to ensure that performance is improved, without any detrimental impact on the environment.

Vehicle emissions have been under extreme scrutiny this year after the High Court air quality ruling in April and the use of defeat devices by Volkswagen Group.

Indeed, it is thought that more than 29,000 premature deaths occur each year in the UK as a result of poor air quality, which is being largely blamed on NOx emissions from diesel vehicles.

“Real world testing carried out by both ourselves and our customers have shown even more significant improvements,” claimed Busby.

“However, now we are pleased to be able to back this up with certified data which confirms the environmental and fuel saving possibilities available with BlueOptimize.”
