was at the junkyard and found a 95 integra ls...pulled the ecu out and it says p54? Looked up all honda ecu's online and every site says this is a 97 edm accord 1.8 ecu..I did a search on here and it came back as 94 del sol with b series vtec...What ecu did I find and will it work on a obd1 LS?

 

Did you ever get an answer to your question about that ecu? I have an ecu I got from a friend, but the i can read up to the p54 part. Have not opened the board to look inside, and what I have found on the web is conflicting. Most links I'm directed to say that is an ecu for b18b1 accord ls jdm/edm with no vtec support. But I found one table that says is for a Domani b18c4 which does support vtec which was sold in edm.

 

P54 or pr4? Pr4 is 92-93 obd1 ls

 

The one I have, I can at least read that it says p54, thank you for any input.
