Hello Folks,
I am a newbie and apologize if this post seems convaluted, 'cuz it is!)
I reviewed the "Reference Materials" section, to no avail. Can someone please tell me what is the model of STOCK ECU for my Accord? I am looking to get a pin out diagram.

Long story:
I live in VA and need to return to stock to pass OBD-2 emissions. When I replaced my P28 9and Hondata s200) with my stock ECU, the CEL went on. The error code was "speedometer error". I found out that my original tuner kluged the wiring. When they replaced the stocker, they added a harness and the P28/s200. I just recently found out that the original tuner is one of the worst in the Baltimore area, so I do not want them to touch it. Two other tuners in the DC-area are willing to restore to stock, but need the pin-outs for the stocker.

Can anyone help me?

Thanks,
Shamun

 

What's your original ECU?

Check out that, that *should* be your stocker, I'd imagine you'd be OBD2b
