The actual ecu part # should be 37820-P08-900. The rest of numbers are possibly serial numbers.

Look at the last 3 digits -900. The middle digit (0) denotes manual while if there is a (5) its auto.

^yup there are variations to this "convention"


-900 and -901 on JDM P08 are known to indicate auto as well.

it is a bit confusing. :(

it's most likely that you would have a Japan spec ecu so it would be auto.
