Why does the DPChip for my vehicle need to be wired in while others are plug in?
A. All common rail vehicles are simply plug and play using original adapter plugs and the DPChip fits in around 5 mins. Other vehicles such as the GU Patrol for example must be wire in for safety reasons. Many people do not realise that the Bosch VP44 pump has another ECU inside the injector pump (called an Injector Pump Control Unit). This is where the other plug in chips plug into so they are still upstream of this ECU. The DPChip comes in after that ECU, which we believe is a much safer system, hence the hardwire connection. Any chip that claims it is after the ECU on that model fuel pump must be wire in because of the inherent design of the pump. Having that Injector pump control unit means it is impossible to be plug in and not have all the inherent potential problems that effecting the signal before the ECU can cause. The DPChip is designed to avoid these problems and our loom must be wired in on these type of fuel systems. Once the DPChip loom is wired in the chip itself then ju
