Its a matching 914 2L brain, the 037.
I did throw the old one back in and it "seemed" ok, but I only drove it a
few miles and its done that before after Ive changed something.
It could well be the connector, Im going to lift the lid and have a look see
for any connection issues, when I have more time I may put the old one back
in for more of a test but for now, im so far behind on things I just need to
keep driving it and this will wait for spring.
I also want to pull apart that suspect alternator, especially if long haul
runs to the camp in the spring show better holding of voltage than the old
one had, so far so good around town though.
yes, its quite a relief having this taken care of as winter bears down...

Hmmm, what brain are you using? What part number, and Type 3, Type 4,
Any chance this was just a contact problem, that might have been fixed by
the action of simply moving the contacts? I'd love to see you go back to the
original ECU to confirm that the problem was actually the ECU. The Idiot's
guide suggests that some problems may occur because of loose contacts in
the brain connector. I've never seen this, but I cut up a scrap brain board
make test pieces that I can slide into that connector to check the tightness
one contact at a time. Need one?
Nevertheless, it's inevitable for there to be variations in the ECUs, even
there's nothing "wrong" with them. Unless this was a contact problem, that's
probably the case here, because I don't see any other reason for your miss
to occur in just one RPM range.
