 A cars ECU (Engine control unit) is programmed to a vehicles immobiliser system and cannot be simply placed onto another car for re-use. A diagnostic scanner used by garages & workshops does not have the capacity to code it to another vehicle. We can transfer data from a faulty ECU to a donor secondhand unit enabling it to work without any further programming necessary using your original keys etc. This method of ECU replacement is far more cost effective than ECU repair with no parts being used from your faulty unit. All you have to do is simply bring or send us your original ECU and your donor unit. We can also 'virginise many ECU's some of which selfcode to your vehicles immobiliser system. We also offer an immobiliser delete service enabling an ECU to be 'Free running' - call us anytime to discuss your needs.
