Hello to all I have a 90 Honda accord Coupe EX 2.2 Auto and was wondering what kind of transmission computer will work with my current transmission computer and model car. Example I was at the salvage yard pulling transmission computers out for my 90 EX and I got one from a 4 door auto 90 EX OR LX MODEL and the other computer was from a 2 door 91 auto EX OR LX MODEL. 1 computer was brand name OKI the other was Denshigiken Ecu transmission computer. So obviously there is some major differences here. Can someone please tell me what the differences are, How I can tell which ecu will work with my make/model accord, and if there is a way to tell from my vin # what kind of ecu transmission computer I have i.e. OKI or Denshigken? Please advise me and thanks for your help as this is a technical matter/question for the Hondas from 90-91.

The only way to know for sure if your accord and the donor accord use the same TCU is to look up the TCU at an OEM parts website like hondapartsnow[DOT]com.

If the OEM part number for the TCU is the same between the model numbers, then they are interchangeable.

 

Hello PAhonda,
Thanks for answering back you said "OEM part number for the TCU is the same between the model numbers, then they are interchangeable." Okay so I looked up this part # Honda Part 28100-PX4-932. So my question to you is where is the model # in this oem part # and how can I tell where it is?
