Diesel ECU upgrades – better economy, better ecology.

ECU upgrade modules work by interacting with the original Electronic Fuel Injection (EFI) Mapping. They alter the fuel injection and injection timing to get the right match of air, fuel and burn rates best suited to you and your vehicle.

An EFI diesel can be returned to accommodate changes due to age or atmospheric differences. For example, high altitude drivers will often have problems with fuel delivery. Because the factory ECU is limited to its standard mapping, this will cause high smoke emissions, high exhaust temperatures, reduced reliability and increased fuel consumption.

An upgrade is the answer! An upgrade EFI Module is not just a modified chip that creates predetermined changes in performance. It is a unit specifically designed and programmed to assist the original EFI system achieve the best power and economy at all times and under variable conditions.
