Nissan Engine ECU
Nissan gasoline engines commonly use Hitachi-made MEC series engine ECUs (e.g. MEC93-620). The letter and number groups following the number indicate the software version. On diesel engines, Bosch ECUs are also used due to the Renault partnership.
On models such as the Qashqai J10, the same MEC number may come with different suffixes. Compare the full code on the label to choose correctly.
