how can you tell if the ecu's from a automatic or manual transmission?

JDM_SOHC

All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. ex 37820-P28-A01

On the ECU the last 3 characters are broken down into 3 parts. "A" generally is used for US ECUs. "G" is European, and "J" is Japanese. There are other versions of this, but you get the idea. The second digit "0" typically means manual transmission, where a "5" means automatic transmission, and the last digit "1" is the version number.

N could be a revision of the ECU....

And also just cuz its N, doesn't mean the word starts with N... United States = A, Europe = G, Japan = J... See, sometimes it matters sometimes it doesn't...
