SCR DPF EGR Off for ALEXANDER DENNIS

Optimize Urban Bus Performance with File Services for Alexander Dennis

We specialize in delivering tailored File Services for Alexander Dennis buses, providing full ECU recalibration to eliminate the drawbacks of restrictive emission systems such as EGR (Exhaust Gas Recirculation) and DPF (Diesel Particulate Filter). These components, while intended to reduce emissions, are often responsible for power loss, poor fuel economy, and frequent service intervals—especially in stop-and-go urban conditions. Our services target popular models like the Enviro 200 ISB4.5, equipped with a Cummins ISB4.5 4.5L engine and CM850 ECU, a common setup across city fleets. By applying our advanced Calibration Files for Alexander Dennis, we restore full engine performance, enhance throttle response, and eliminate recurring emission-related errors. Operators benefit from smoother operation, reduced maintenance costs, and maximized vehicle uptime, ensuring reliable and cost-effective transport for every mile driven.

All models of the brand might not be listed due to the extensive scope of work, but we can operate on 95% of the brand's fleet.
