Generic Nissan Ecu Sensor Or Data Register Table Ver 2

Generic Nissan Engine ECU Register Table. This is a list of all known registers and their function. Any particular ECU will only respond to a sub-set of these depending on the engine type and configuration. Please report inaccuracies back to the Nissan Technical egroup.
