Scangauge installed-amazing difference

[red08fit]

I finally decided to order a scangauge and after 24 hours of installing-it has really surprised me! Before the scangauge, I was averaging 34.5 with an occasional 37mpg in my MT Sport. So far on this first tank with the scangauge-44.5mpg with one trip hitting the 50mpg mark! Definitely helps with hypermiling techniques and will end up paying for itself in less than 3 months at this rate! I'm sure after another couple of days I'll have refined the techniques even more. I found it best to pulse from 50mph to 60mph fairly quickly then shift into neutral to get a longer glide.

Ill have to try that pulsing technique..

[GD3-Fit]

eh? so it tells you how to get better MPG?

[pb and h]

NO, but it is like a scale(someone else made else here made that analogy ). The gauge will give you instant feed back. The driver can adjust the driving technique to get a different response from the instrument. Very useful tool for achieving better mpg, assuming you know what techniques to use and how.

I just purchased a SGII 2 weeks ago and I love it. I should of bought one a long time ago.

[GD3-Fit]

how much and where to get one?

[red08fit]

$159.99 with free shipping off ebay, also amazon or jcwhitney have them for I think a little more. Just let me say that I tried the pulse glide techniques for a week or so before the scangauge and I actually got LESS mpg, so it really does help to have the instant feedback to let you know what works and what doesn't work. I took a short 25 mile trip today and averaged 58mpg. In addition to the 50-60 pulse in 5th gear, I tried 40-50 pulse in 4th gear and it seemed to help a little. Instead of setting the scangauge on "gauge" and watching the instant mpg, I've been setting it on "trip"-"current" and use the pulse and glide to gradually increase the trip average. On average, the pulse will cause a decrease in about 0.5-1.0 mpg depending on conditions, and the glide will cause an increase in about 0.8-1.6 mpg. So your goal is to note your avg mpg exactly when you pulse, then after the glide be above where you started. Using this method, you can vary your techniques and know what works best.

cleanmpg.com - become a member and get it for $149, sometimes you can get it for $139. That includes shipping.

I use the gauge function to watch Load, instant mpg, average mpg for the trip and voltage or water temp depending upon the driving circumstance. Instant feed back FTMFW!

bump for cleanmpg.com

also, sorry, the OP just sounds like this in itself gets better MPGs in the Fit...

Out of curiosity, when you set it up, did you program it for a 10gal or 11 gal tank?
Since the fit is 10.6 u.s. gal, I rounded up to 11. Even when I had instant feedback and I adjusted my techniques I didn't get as huge a difference as you.
For me it was more like 31mpgs before SG to 34-35 after.

Unless you were driving like it was stolen before the SG then driving like grandma, I'm a little skeptical.

[solbrothers]

for me, it went from like 33mpg before, to 45-55mpg. depending on the weather

[MINI-Fit]

Scangauge II a good learning tool for any driver.

For the Fit with manual transmission it's very helpful.

For the Automatic it's interesting but may not be worth the effort.
MPG is definitely not as good for AT in 2007-2008 Fits. On the highway about 32-33 mpg for me if that much, daily driving about 25-26 no matter how much effort was used with the help of scangauge II.

There is also a "sticky" ScanGauge thread;

How much work is involved in putting a Scangauge in a Fit?

[CBX]

I probably spent the majority of the install time rummaging through the kitchen junk-drawer for the black industrial velcro I knew I had.

In the '09 Fit, the OBDII connector is easily accessible above your right knee. After a test-fit in several locations, I settled on placement above the compartment at the front end of the console.

Surprised no mention of how most of the time the SG is optimistic for avg FE. Don't get too excited as a new user.

The more sophisticated you techniques to save gas become the worse it gets. Mine is off by 13% now. P&G is the biggest.

Miles drive is within a few percent unless you have the key off and coast. It's fuel flow thats off.

It turns out that the scangauge was off and after I calibrated it after the first fill-up I've been getting 40mpg average on the last 2 tanks. I don't drive like a granny (before or after scangauge). I simply pulse and glide with an average speed 5mph above the speed limit (example: speed limit 55mph-pulse at 55mph and glide at 65mph) I drive to Knoxville from Chattanooga and back frequently, so I decided to try setting my cruise control at 75mph on the interstate going to Knoxville. I got an average 32.8mpg for that trip. Then on the way back from Knoxville I used pulse and glide with the same avg mph (pulse 70mph, glide 80mph) and I got 42.5mpg for that trip. It was about 10 degrees warmer coming back but still that is a great improvement. I've been getting anywhere from 46 to 53 mpg trips in the city, so the interstate driving is what kills my mileage because of the higher speed. I set the tank size to 11 gal also. Does anyone know if the constant pulse and glide (going to neutral) will harm my clutch? With this technique, I'm only getting a glide about the same length as my pulse unless it's downhill, so I'm constantly pushing in clutch shifting to neutral pushing in clutch shifting back into gear.

[sevenaprils]

I'd think you'd wear the clutch faster by going in and out often with P&G like that? Anyone else with evidence/better info?
I think I read somewhere that its negligible difference between completely letting off the gas or shifting into neutral at speed. I could be wrong because my memory is a little fuzzy.
Maybe see what the closed/open loop on SGII says??

I've heard setting the SGII prefs to hybrid vs. gasoline or diesel also helps, since you can squeeze the same if not better MPGs out of the Fit compared to say a Prius. I think it has to do with those who use FAS or if you turn your car off at lengthy traffic stops - the SG will not reset itself/turn off after a few seconds of the car being off.

I am interested in the results for the "pulse-glide" technique. No matter what or how, you still have to move so many pounds so many feet. I cannot see any tricks resulting in a free lunch, but am always willing to be proven wrong. The foot-pounds rule is iron bound. There is no way around it. So I want to really see how folks can consistently get around this. Lemme know.

[pb and h]

Not being a smart ass, but if you want proof, then try it. If you can't figure how to do it then search. P&G works, I didn't think it would either until I tried it. I like to say, the proof is in the pudding. The question then becomes is it worth it to you?

Good luck

Questions: these amazing MPG increases, are they actually measured by gallons divided into miles or as indicated by the gauge?

And what does the gauge tell you that the gauge already built-in does not? They both indicate a real-time average MPG.

Has anyone actually tested this or is this all in the "I am now getting 80 MPG since installing <you fill in the blanks> on my car."? An actual test would compare indicated MPG against actual measured MPG and compare the SC against the gauges in the car already, several times and in several cars. A test sample with an observation of one is not always accurate.

In the time I have been driving I have gotten some amazing average MPG on a tankful. It was always measuring error as the next tankful was low and the two would average out to about what was reasonable.

And again, to move a 2,000+ pound object over a distance of x miles requires energy. Unless you increase the efficiency of the propelling device or reduce the friction inhibiting the motion of the object I cannot see how you can actually achieve any real change in MPG.
