Diesel Injector Coding Equipment

After the ecu or injector is replaced injector code of each cylinder must be confirmed or re coded so that the cylinder can better identify injectors to accurately control fuel injection.

Diesel injector coding equipment.

Merlin s s1000 will give your injectors this offset correction code. Using the on screen directions change the existing code to the new number supplied and select write to ecu. Coding the injector we make adjustments ideally balancing the hydraulic parameters of the electromagnetic nozzle and in the case of piezo bosch also electric ones. Delphi denso and continental vdo systems all require this information and our software provides you with this capability.

Diesel injector coding and pilot learning common rail diesel injectors are manufactured with very tight tolerances however slight variations will always occur and as such all new injectors are tested and then stamped with a coding number which is used to inform the ecu how much compensation is required to achieve the optimum in lowering emissions and provide smooth running. All common rail diesel engine s need a calculated offset made by the ecu to ensure the injectors work cohesively with each other and optimize performance. Injector coding scan tools can be used to programme a new code to the ecu for accurate communication and injection control.
