One other thing to consider is that some Flo-Scan
gauges can be tied in to a GPS and actually read out
miles per gallon.
I'd sure like to install one of their dual gauges
on my boat that uses a pair of 454 GMC engines.
Don't complain about 10 mpg on your GMC coach. I'm
lucky to get 1 mpg at 9-10 mph.

Boats like the gas alot, my friend said it best when he said B.O.A.T. meant "Break Out Another Thou". in some aspects our GMC is like a land boat, I think a fuel consumption meter would be great to measure MG and find the optimal cruise speed for a coach since some are more modified then others, it would make it exact science out of mpg rather then approximations made between fillups...

I have not found a price on the Lowrance yet. Do you know about what they sell for? I have the scan gauge on Teri's Vibe GT and love it. I would love to have something like this on our GMC. Lowrance is a good company and I would trust their work.

Zemco made a computer for automobile use with carburators in the 70's and early 80's. It gives a lot of information above the fuel mileage, average and instantaneous consumption. You can find one occasionally on Ebay that usually go for around $75. They work pretty well, I have had two of them over the years. Just type in zemco in the search and sometimes they are available, sometimes never used.

I remember those zemco things...
What about adapting one of those units that GM and Chrysler used to put in their higher end cars? they usually ran off of RPM, vacuum, etc...
It is a cool idea.

IIRC didnt those computers use a vac signal to compute their MPG? the thing I like aobut the fuel consumption meters is they have a device which plugs into the fuel line and accuraely measures fuel as it passes though which makes it very preceise as to how much fuel you are burning.
I would estimate the floscan unit we sould need the gauge head showing 1-10 or 1 to 20 GPH since I the needs of a coach is a little different then a boat, the only tme I think one might exceed 10 gph is during WOT with secondaries open.
looking again at the manual for the Lowrence unit, it says to make the gauge work properly you need their network hub, so I dont know if it will function as a stand alone but the floscan will.

I wish they were still available. I had one and it worked well for a long time but, over time, various functions started "disappearing" and I finally removed it. If I found one NIB, due to age, I would have to wonder how long it would work. But for a reasonable price I sure would give it a try. Once you got it calibrated, not hard to do, it gave good results. I like the cruise function where the desired MPH could be entered for cruise. It had a lot of functions that were unheard of at the time such as miles to empty and gallons remaining.

I had one of these on my first GMC and found it to be great once you
got it calibrated. As Steve noted it had many functions, one of which
I liked was that you could switch from MPH to Kilometers. However I
also found that the inline fuel consumption device would starve the
engine on a hard pull and if you disconnected the 12v power then you
would have to re-calibrate which was a PITA.

Installing the LMF-200 would cost MUCH more than 2 bills.
from the manual:
| Quote: |
... This gauge will only work with a NMEA 2000 network. It MUST be connected to a NMEA 2000 network or it WILL NOT function. When properly installed, the LMF-200 will display information from a variety of Lowrance Electronic Probe (EP) sensors and other NMEA 2000 devices connected to the network. ...

NMEA 2000 network is a "boat" variation of the CAN Bus used in many cars. Looks like neat stuff but it would require more research and thought to put a system in.

yeah I found that out, which is why im leaning to the floscan unit which is a stand alone. those are $290 out the door...

I dont know if it will function as a stand alone but the floscan will.
________________________________________________________
According the the boat guys, the Lorence will operate as a stand alone for fuel measuring, per hour, I don't know if it would do total gallons, I cant find the manual.
If you want miles per gallon, you have to hook up the network with gps so it can get bearings to make measurement.
Guess boats done have speedometers to input this info.

you know another thing I was thinking is the floscan gauge is the fact that the fuel use totalizer would be extreamly useful for determining an exact MPG. normally you fill up, look at the milage, then when you fill up again you take into account the miles traveled between fills and devide that number by the gallons used to fill to get your MPG. however given the nature of the fill necks in our coaches and how some gas pumps like to shut off sooner then others, this could throw off the MPG total a lil bit. with the fuel totalizer, you just reset it at a fill up or just log down whats on the totalizer and our starting milage, then when you get to where you are going, you have an exact amount of fuel used over an exact distance giving you a very accurate MPG, this would even allow MPG calculaion with out filling a tank, and average MPG over a short trip as well...
Happy Thanksgiving all!
