ECU remapping of a van’s electronic brain can transform performance and driveability without dramatically affecting economy.
Most think of racing cars or high performance road models, but the same thinking can be applied very well to vans or pick-ups which have a heavy job to do every day.
In tests, a Renault Traffic van had its horsepower increased from 90 to 149, and its torque in Nm was raised to 334. With power gains of over 50 per cent, the ECU mapping had a significant impact on the overall running of the vehicle.
In a Mercedes Viano van that runs on a 3 litre diesel engine the horsepower was only increased by a modest 27.5 from 236.5 to 264, but the real difference was seen in the torque. The remapping saw it rise from 477 Nm to 614 Nm, a figure above that found in a BMW M4.

At the garage, the engineers also performed tests on Isuzu D-Max and a Mitsubishi L200, both pick-up trucks, and found they provided similar results.
A spokesperson for GAD Tuning, who can use their racing expertise for CV users, said, “What we have seen here is the full benefits of ECU remapping being exemplified by a selection of vehicles that you wouldn’t normally associate with top-level performance.
