When I unscrewed it and examined it, I noticed a qr code. When I scanned it, I am sent to a website that no longer exists.  The website was Installapart.com. It appears that Installapart is no longer in business.

I found your Ford doppelganger from 2021.

"There is nothing I could find on the Computer that indicated where it came from or what calibration it is for. The only thing it had was a QR code that directed me to a site called "installapart" but the site itself looked closed."

You can see the site using the internet wayback machine: https://web.archive.org/web/20180307072216/http://www.installapart.com/

Thanks!  This was certainly an unexpected and unfortunate discovery.  I wasn't able to track down how to troubleshoot the ECU - those pages are probably long gone or that institutional knowledge died when the company went 6 feet under.  I have had nothing but trouble with aftermarket parts that one of the PO's installed - first the fuel pump now this.  I guess I am at a crossroads - Do I try to source a working 1976 Datsun 280Z ECU, go down the Resto mod path of installing a FAST ECU or other replacement system, or continue to struggle and troubleshoot with what I have (even though it may be an exercise in futility)?

Zed Head - that is Interesting, thanks for finding that site.  The OP never does say what he did with the ECU.

My 2 cents (45 cents)

If I owned a 280z, when I started having problems with the factory EFI system, I would ditch it and go to a more modern more easily tuned system
