I recently had the dealership diagnose my car turning over but not starting problem as a bad ECU.

Since its easy enough to replace I ordered a used (but tested) ECU from a salvage yard. Only catch is, my car is a 1996 Honda Accord DX the ECU part number is 37820-P0J-L60.
When the ECU arrived, I realized the part number was swapped out for the LX model of the same year, the 37820-P0J-L51.

The seller tried to alleviate my concerns by saying that they are interchangeable, and I want to believe him because the car starts like a charm now. However, now I have a check engine light for P0441 which wasn't there with the old ECU.

I have 5 days to pass smog in CA. I've already tried clearing the ECU and smog...they caught on since OBDII hadn't gone through its monitors, sent back for retest.

Since the car starts and seemingly runs just fine, should I trust this ECU and start chasing the Evap code?

Are these ECU part numbers really interchangeable?

Let's talk.

Those are interchangeable Cali emissions ecu's, yours was just an updated version (hence the -L60 )

Anything I should worry about with the older version? Nothing that would cause it to throw bad codes with older version is there?

Thanks for your help! I've been getting a lot of answers both ways, but not much from actual Honda specialists.

You shouldn't have any troubles whatsoever with than ECU. I'd double check all vacuum lines going to the evap canister, make sure the evap is all working properly, and that gas cap is in good condition.
