so looking to get a new ecu and the first number matches with other parts but the second number wont match with any of the parts in finding. Is the first number the most important? let me know thanks!

numbers:
37820-pob-a51
381-299091
BA5

 

The 37820-P0B-A51 is the number to match.... This is for a 94-95 (OBD1) F22B2 Non VTEC automatic Accord. Correct?

 

Yes sir!

 

OK so any ECU listed for a 94-95 (OBD1) Non VTEC 2.2L F22B2 with A/T will work. You may find a few with the last three digits that are different.
