Digital MPG indicator?

the Veypor gives instantaneous mpg readouts and a bunch of other stuff and you can get it for 130.00

"Want more info on your mileage, how far a tank gets you? Don't have a gas gauge? The Veypor fuel estimation tools accurately predict fuel use, distance remaining on a tank, instantaneous and average mileage. Track how far you've gone on a tank with a separate tripmeter and see your fuel level with the fuel gauge graphics."

I don't know how accurate that would be. It just looks at your engine RPM and your speed. I think you have to tell it what your mileage was at one point and then it will guess for you. Thing is, I can do that math in my head for free... All I need to figure out how much gas I've got left is the existing trip meter and a memory of the mileage from the last tank of gas...

Eeew! 

This one is all old and wrinkly.

Throw it back!

It will prolly throw some random number and call it your mileage.
Cool.

Now even I can do THAT in my head.   

They Veypor has an optional Cylinder Head Temperature pickup, I believe. That would be fun.  But it doesn't plug into the vacuum system anywhere, so how much fun could it REALLY be?

I played around with a vacuum gauge almost 30 years ago in my 1972 Plymouth Duster.  Slant six (198 ci) with a ONE-barrel Holley carb.  Just by watching the vacuum I could make the car get WAY better mileage and run cooler.  Unfortunately, you had to go really slow up hills and really fast coming down them to do it (Honest, officer, I was AVERAGING the speed limit).  It has intrigued me ever since! 

A cruise control that allowed some "play" in the set speed but maintained (as close as possible) a high vacuum figure would be cool.  For example, set it at 55 mph on a 70 mph limit.  Allow up to 75 mph going down hills and 55 going up them.  I'd be willing to bet a few beers that fairly remarkable gains in mileage could be achieved (at the cost of lower average speed).

(from DoD#1):
The basic reality - drive like an old fart, get better gas milage.

Pretty much!

In 1980 my parents bought a shiny, new kaka-brown Chevy Impala wagon with a 3-speed shifter on the floor.  Anyway, they went to Sears and had a cruise control installed. From my point of view (in the back seat) it consisted of a black plastic pod that was zip-tied to the turn signal stalk. On the tip of the pod was a shiny black button for setting the 'hold' speed at cruise. Out the back of the pod came a black plastic tube (which I'd bet money was plugged into the vacuum system).  I remember the semi trucks passing us on the uphills, and my mom's screaming panic as my dad let the car run freely down the hills.  Can you say vacuum-regulated cruise control, anyone?

Perhaps the origin of my foolish infatuation with vacuum tubes?
