ECU Remapping in Harrow
Stage 1 ECU remapping is one of the most popular performance enhancements for Harrow drivers. Our expert technicians reprogram your vehicle's ECU to increase boost pressure, adjust torque limiters, and optimise fuelling maps. Most vehicles see 10–30% more power and torque, alongside improved fuel economy in cruise driving. Your original file is securely archived and can be restored at any time. The entire process happens at your Harrow location – no transportation required.

AdBlue Delete in Harrow
AdBlue / SCR delete is a software-only solution that disables the selective catalytic reduction system through ECU reprogramming. We don't physically remove any components – the system is simply emulated in software. This eliminates expensive AdBlue top-ups, removes false warning lights, and restores some lost power on diesel vehicles. The service is delivered entirely at the customer's Harrow premises, with no downtime or transport logistics.

Diesel particulate filter delete removes DPF regeneration cycles that reduce reliability and performance. BSG's software approach reprograms the ECU to disable DPF monitoring and cleaning routines, ending constant throttle-up incidents and improving throttle response.

EGR Delete in Harrow
Exhaust gas recirculation (EGR) valves are prone to clogging, causing misfires, rough idle, and limp-mode activation. BSG's EGR delete software disables the EGR system at the ECU level, eliminating the root cause of these problems without requiring physical valve removal or component changes. Harrow vehicles regain drivability and responsiveness immediately. We perform the remap at your location – no vehicle drop-off needed.
