Fuel Economy instrumentation - do you use it?

[diesel_john]

just started using the KEL in my truck.

it does work on any MFI gasoline or LPG engine.

uses the pulse width and the VSS signal. it does not have all the functions of the super mid but i am still checking accuracy and learning the functions.

second pic the KEL is on top of the dash, left side (2008)

mid 30's - my mpg driving like a normal person
low 40's - mpg hypermiling with no instrumentation
low-mid 50's - hypermiling with a scangauge

It's no contest, it helps absolutely.

And P&G works wonders on the highway, too. I took a 200 mile trip (400 round trip) a few months ago. P&G with a 55-65 mph range on the interstate = 55mpg. On the way back, I set the cruise control at 65. The terrain was mostly flat, so hills were not an issue. 43mpg.

I will soon.
I haven't yet.

WHOOPS,
On my mechanical injected diesel i mounted a throttle position sensor near the pump linkage and attached, so that under like conditions, i can compare A vs. B vs. A mods. Just by reading the ohms across the TPS. would apply to carbureted engines, to compliment vacuum.

On pre ODB injected engines, you can also compare % load if you have an accurate dwell meter. JUst hook to an injector to get the percentage of time the injector is open. Under given conditions, same gear, speed, road, day, etc. you can compare A vs. B mods. for example windows up vs. windows down.

I recently installed a scanguage II. I have it set on IGN RPM WTP and MPG

[PaleMelanesian]

That should be useful sometime soon. I like the Scangauge.

Another useful instrument to have in a FE oriented car is a voltmeter so you can monitor your battery voltage, especially useful when FAS'ing at night when outside temps are well below freezing.

[PaleMelanesian]

I absolutely agree! In my case the Scangauge does that, but everyone should have one.

Instantaneous feedback is important to me. I have two daisy chained scan gauges and the Prius MFD. I monitor RPM, SOC, IGN, Tank Ave MPG, Instantaneous MPG, Water temp, and two different Current Ave MPG's. That is 8 gauges total. In city driving I watch the MFD arrow display to help engage and control stealth and warp stealth. I use RPM and IGN to help engage and control super highway mode. I also have a GPS which I use to monitor cruising speed (highway) and elevation.

Elevation? Which model has that?

I have double ScanGauge envy now! 4 isn't enough but I could get by on 6.
