Sounds like you've been taking advantage of the nice weather.
That definitely seems like a low number considering all the black smoke. I would have expected at least 1200F-1300F.
You could buy a 12V to 24V DC step up converter to run your Auber. Would be a lot cheaper than buying a new pyrometer. Maybe something like this:

Yeah, not just the number but how slow the gauge was to react. Clearly something wasn't right.
I dug the auber out to do a side by side....note the scientific testing aparatus.
Out of curiosity, I hooked it up to just a pair to see if it worked on 18v....it did. So then I had to try 13v. and yup. appears to work just fine....ordinarily I'd email the company in question and see if it's kosher to run it on lower voltage, (the flashing led is good for 8-32 v or something like that ) but my last communications with that "Suyi" person who answers emails there were largely in "all caps" and rather impolite. Long story. Won't be asking him(her?)
Don't most of those little 24/12 jobs work both ways? Just a gauge from auber is pretty cheap, but I'd have to get someone else to order it...doubt they'll send anything to me again after our last conversations...
So yeah. It's all installed, and to be honest, looks better than the isspro anyways. Switch and blinky light above are for the afterglow. Blinky light is freaking bright, so pretty hard to ignore when it's on. still may find a timer relay, but low on list.
And now that glow and afterglow function, and I advanced the timing a bit, cold starts are much better. It always caught and idled, would just start to stumble after a bit with no afterglow, and could fumigate bc place when you revved it up.
Took it for the obligatory "drive the grandmother out of it" test drive with gauge installed. Got it up to 1100 and change on the henry road hill. So pretty much what you'd expect, a lot like a 3b. There's room for a bit more fuel, but I'll leave it for if or when I turbo.
Got 30mpg on the first tank. With a fair bit of that doing 60 in 4wd, so it might improve. Haven't checked accuracy of speedo tho. I was hoping it would get at least close to 30, so I'm ok with that.
