If you plan on leaving the car stock, use a stock ECU.

All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. e.g. 37820-P72-A01
The part number consists of three components:
Honda's part number for ECU, which is always 37820
Three characters (which are loosely related to the model of car/engine). e.g P72
Three characters (which are the revision of the ECU) e.g. A01 or G52
The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters. e.g. a P72 OBD I ECU is different from a P72 OBD II ECU. Here is a list of common ECUs:
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.
