Stage 1 remapping in Hounslow
Moto Heston Services sits on the M4 just 2.5 km from Hounslow, and the M3 is also on the borough's list of main roads, alongside the A4, A30, A312 and A316. With two motorways on that list, plenty of journeys can include a slip road and a stretch of fast traffic. That is where Stage 1 remapping is easiest to feel: on a diesel, extra mid-range torque brings the car up to speed with less effort and makes overtaking less of a stretch. The change is made in software, to the fuel, boost and timing settings, within the engine's limits. Fuel use changes are modest and depend on how you drive.

Driving in and around Hounslow
In the 2021 Census, 29.4% of working residents in the Hounslow council area drove to work and 14.5% travelled 10 km or more, while 32.8% of households had no car. Petrol leads the private fleet: 66.4% of privately kept cars in the council area at the end of June 2026, with petrol hybrids on 11% and diesel on 15.2%. In 2025 MOT tests across TW postcodes, the Mercedes-Benz E Class and C Class were the most tested diesel cars, and the Ford Transit and Mercedes-Benz Sprinter led the vans. London's ULEZ covers the borough and charges cars and vans, and a remap leaves the emissions standard unchanged, so the charge is unaffected. Richmond upon Thames is 4.4 km away and Ealing 6.5 km.
