Greetings to all. I just joined and am looking forward to being a part of this.

I'd like to start with a question. Short version is, what is the correct part number for the 91 Civic Si ECU, 5 speed, multiport injection and programmable ignition? This is a D16Y7 motor. With that said, I need one. Just don't have the original.

Any help out there?

 

Local parts house confirmed that it is a PM6 but I'm still getting two options there. By "programmable ignition" I mean the timing variables are controlled by the ECU. Initial timing has to be manually set at 16 degrees BTDC.
