Fuel flow meter?
My boat has extensive fuel mgmt capabilities, I can glance anytime at my burn rate in gallons per hour (ouch).
Does anyone make an aftermarket device for cars/trucks that would do this or something similar? The typical mpg readouts that many vehicles have seem inaccurate and dont provide instantaneous data.
Really what I'd like is to see how much Im burning at what rpm when towing but also Id like to see what highway speed yields optimum economy.

The higher end power programmers give fuel readouts, but I don't know if they make one for your truck. You can read that sort of info on a scanner, but then you have to drive around with a scanner plugged into the truck.

Yes, for about $170 you can buy a Scan guageII and it will give fuel burn rate and a whole lot more. I have one more for the curiosity, and find its not that usefull, but it'll give you a ton of info.
BTW, it plugs into your OBDII port...pretty simple.

The Scangauge II uses either data from the FLI sensor or from calculations derived from the MAF sensor. It does not and cannot provide "real" fuel flow data.
To do so, you'd need to install a flow meter sensor in the fuel supply line to the rail (and another in the return line and use the difference if not a returnless delivery system).

Anyone know where to get a set of these, and how much? Or even better, a single unit "differential-flow meter"?
I'm curious to know the idle fuel consumption rate on my 12.7L Detroit...
"Industry Standard" figures state about a gallon an hour; observation indicates substantially less. I'd like to know how much less. Anything less than .75 GPH substantially undermines the affordability of commercially available anti-idle solutions, and observations seem to point in the direction of .5 to .7 GPH at idle.
(incidentally, the S-60 does not use an OBD-II interface, but an SAE J-1708 data bus.)

FWIW, My V10 uses about .8GPH at idle, my 4.6 Towncar is about .5 - .6GPH

Actually I think its derived from the pulse time of the injectors...either way it is not directly measured but it is fairly accurate, as it also determines number of gallons consumed, and that seems to be right on.

Thanks for the tips. Its actually a Chevy 5.3 (gasp) that I tow with though I'd like to know the highway burn for all my vehicles. I have a scanner, Actron or something its called, I dont know if it does fuel but I'll look. I had bought it read codes so Ive only barely used it.
