With over 25 years of diesel and petrol fuel injection experience, we are pleased to announce our expertise in Engine Control Unit (ECU) remapping. Modern engines are governed by sophisticated computers and for a considerable period of time original manufacturers’ ECU’s were not reprogrammable. Now however we possess state of the art microcontroller readers which enables us to read and modify up to 90% of the vehicles in the Sri Lankan market.

Our performance remaps will deliver up to 30% increase in power and our economy remaps will deliver up to 20% increase in fuel economy. Furthermore we give solutions to Diesel particulate filter (DPF) and Exhaust gas recirculation (EGR) issues.
