i was just browsing around on automotiveforum.com, and tell me im crazy but i was reading this post about an automatic B18C1. haha. i dont know about this one:

"Whats the ECU code for a b18c1 like p30.. etc. Thanks i'm really considering getting a Auto B18C1 swap instead of a manual B16a2 swap. Since i found an auto b18c1 for about $200 dollars more. Thanks ahead."

any thoughts? i may be dumb but how the f*** is this possible?

 

B18C ECU is P72

 

All Honda ECU's have a part number which is located on the side of the ECU and inside on top of the ECU connector. (Example 37820-P72-A01)

* The middle three characters are the most useful to identify what the ECU is (Example 37820-P72-A01)

* The 37820 is the general Honda part code for Engine Control Unit (ECU) or Engine Control Module (ECM).

* P72 is the code for the engine type, in this case it's a Integra GS-R.

* A01 is broken down into 3 parts. "A" generally is used for USDM ECU's, "G" is European and "J" is Japanese. There are other versions of this, but you get the idea. The second digit "0" usually means Manual transmission, where a "5" would mean Automatic transmission, and the last digit "1" is the firmware version number. I've seen these from "0" up to "3".
