Like the topic says, I need to know the part number on the side of the Mugen N1 ECU. Basically, I need to know if its a P28, P73 or what !! Thanks !!

"This is a complete Mugen replacement non-programmable ECU. Mugen does not produce or sell ECU chips, stock ECUs with replacement chips, or programmable ECUs."

None of the above.
I have one sitting here but an exterior pic won't do you any good!

 

From King Motorsports website re: N1 ECU

This is a complete Mugen replacement non-programmable ECU. Mugen does not produce or sell ECU chips, stock ECUs with replacement chips, or programmable ECUs.

I used to have one of them - they are not like any Honda ECU. They use an OBD1 harness though.

Plugs into a 97 w/o an adapter harness.

 

That is EXACTLY what I am looking to find out .. So the Mugen N1 is in fact an OBD1 ?? The situation is that I bought the harness from a friend who was using a Mugen N1 on his 2001 ITR and it worked fine.. However, when I installed the harness on my 2001 ITR with a JUN ECU (P73) I'm seeing several problems.. If the Mugen N1 is OBD1 that would make sense because the JUN P73 is OBD2a ..

this should have been your initial question instead of the blurb in your first post

 

Ouch man !! Be gentle, I've had a long day I figured with the ECU number I could cross-reference it and find out if it was OBD1 or what .. but thanks anyway !!

 

37820-XH4 is mugens part number for the DC2 ITR ECU. and if anyones interested:-

37820-XG5 is the EG6 ECU
37820-XG3 is the EK4 ECU

 

Does anyone have a picture of the Mugen ECU where the harness is connected ? I want to see where the pins are located.

 

I'm short of storage space but will leave these up for a couple days for you. Ed
