Hi everyone. I bought an ultragauge about a month ago and I have attempted to
calibrate the mpg by calibrating the amount of fuel I pump at the gas tank and then
letting the gauge know that I fill up the tank. However, I forgot to do that
last time I filled up the tank. And when I filled up the tank today it said that I
used "33.83" gallons of gas whereas my tank only holds 18.5. I attempted to set
it back to 13 gallons (what I really used since I last filled up the tank) and it doubled
my gas mileage. Telling me I was getting 70 mpg when I actually got 28. Is there
any way to fix this or should I just set it back to factory settings and calibrate it anew?

Good Luck! ScanGauge has just came out with the ScanGauge-e. It is a lower price ScanGauge. You can't beat the support from Linear Logic and the 18 gauge function of the all new ScanGauge-e.
Here is the link to the ScanGauge-e article on the home page. (http://www.cleanmpg.com/forums/showthread.php?t=39050)

MPG graph is on the main screen all the time and you can read and clear OBD II coded too.

For ease of use and lifetime warranty, buy a ScanGauge II.

You'll be able to correct the offset in the UG the next time you fill up.

For future reference, what you should have done, if you kept the receipt from the last fill, simply add the two fills together, how much you pumped this time and last time, and used that amount to calibrate. It may have been off a little, but far more accurate than a half fill ;)

To start off closer, you can just go refill your tank now, and reset the factory calibration, and just wait through the tank to do another calibration.

I thought the warranty was only "1 year limited warranty"... and not lifetime? that sounds too good to be true?

Thanks for the advice!

Is it supposed to keep a running total of how many gallons of gas you have used?

Or did I really mess up?

I write down how much gas I pump and keep it in a log so I can recalibrate it based
off of that. That was a good idea!

The gauge keeps a running total of miles driven and gallons used since the last time you reset it (using the fillup menu). You'll be able to reconfigure it fairly easily. :)

Wish I could answer your question. You got some good advice that will work. I just got my UG on Thursday and love it. That being said. I am truly disappointed by the the long time SG II users on this site. Why all the attitutude against the UG?

The reallity is we are all here to see how far we can stretch a gallon of gas. Just because we use a diiferent tool to do it so what.

It's funny how since the SG is the "official" tool of this site, that the UG is looked down on by the SG users. I know each one has it's strengths and weaknesses. The truth is competition is good, to all you SG users that now have a lower priced SG with graphing, you can thank the competition UG for the added feature and lower price point. See competition is good, right?

There is a place for both of these very capable tools and ultimately we each have our own criteria as to what is most important as far as price, functionality and ease of use for the end user.

I would really like to see the thumbsdown on all the UG posts I have seen, go away, seems kind of childish and really tarnishes this sites credability to the casual observer.

Just a quick reply... Will say more later, but the thumb down is put there by the original poster, not a moderator here. I will also say that, as an SG owner who now also owns an UG, and is thoroughly enjoying it, as it does not seem to have the issue the SG seemed to have with my vehicle. For a while, the only fully versatile tool available... but not all of us are anti-UG ;)

Hi Brandon,

Thanks for the reply. I wasn't saying the thumbs down was done by a modertor, sorry if it seemd that way. It just seems like many SG users tend to tell UG users they should have got the SG instead.

I looked at both and for right now the UG fit my budget and needs. I very well my get the SG also so I can see if one is better for my needs over the other. I wonder if some of the SG users who downplay the UG have even seen or used it? I just hope it isn't a case of the typical forum fan-boy mentality I have experienced on other forums I frequent.

The reallity for me has been the out of the box thinking that Wayne used to start the hypermiling scene is great. I know Wayne uses the SG and that it cetainly is a more powerful tool for the hardcore hypermiler. I just feel that the UG is easier to use fo the casual newbie like me. I very well may turn hardcore and need a more powerful tool such as the SG.

Don

Just got the Ultraguage today !!!

have some questions

q) what is your strategy for having a less cluttered setup w/ minimal wires showing?

* I connecting wire is quite long and dangles... any tips on how to tuck it away + also best location on windshield (i go to school in camden and dont want any curious thiefs getting any ideas)

q) whats the best setup for guages? (in your opinion)

* i have rpm, instant mpg setup for now


q) what is code 9141?


q) (this may sound stupid but..) how do i best take advantage of this thing?

* i keep glancing @ the screen but how should i use the display to change my driving habits from now on... i've already discovered that sometimes driving @ higher speed (44+mph ) is better than trying to go 35 mpg... any other ideas.


q) * i got 9141 then 34 ~ something guages found... i can't find what code 9141 means... check engine light is OFF


So glad i went for the ultraguage instead of spending almost double and going for alternate brands... this suits my needs very well for now. The display is soo easy on the eyes and i like its compact yet large screen.

Sorry for random questions but just want to see quick results b4 i empty this tank

ateebtk,

9141 is not a trouble code, it's the OBD II protocol that your particular vehicle uses to communicate.

As for what gauges to use, that is entirely up to you. I just got my UG last week so I'm a newbie with it also.

On the first page I have Instant MPG, TPS which is throttle position, Instant G/H , engine Load,Average MPG and ignition timing.

In the Fiesta with 2 scangauges we are using the following gauges. They should all be available on the UG as well.

Instant MPG - keep this above AVG and you'll keep improving.
AVG MPG - keep this going up... and up and up.
LOD - moderate LOD is good (50-75 in an automatic), but keep a close eye on the rpm - that needs to be low first, then look at the LOD
TPS - helps you fine-tune your right foot

GPH - another reference to go along with LOD and TPS but it doesn't really add anything
FWT - the Fiesta has no temperature gauge.

question on "engine load"... my engine load is always 35-47 max ... SHOULD it be 50-70 OR should it be as low as possible.

When accelerating in an auto you want the Load 75-85. When cruising it depends on the car.

Just once, for a test, try a near-full-throttle acceleration and note the LOD value. Then look at the idle LOD. When accelerating, aim for 1/2 to 3/4 of the difference between them.

Example
idle 20 LOD
max 60 LOD
aim for 40-50 LOD while accelerating.

For steady cruise, keep it as low as you can while still maintaining speed.

I just started with the Ultragauge as well.

LOD This is the same as % engine load?

TPS, is that literally the % the throttle is open?

Yes, LOD is % engine load.

TPS is not a %-age, but a numerical value assigned by the manufacturer. Bigger number is still a more open throttle. You can find the max value of TPS just by pushing the pedal all the way down with the engine off and the UG on. With the SG you can program an XGauge that will display % throttle.

The UG has two TPS options - one is the TPS setting, and the other is Relative Throttle, which is the percentage (0-100) that the throttle is open, relative to idle and WOT. Set the gage to the TPS and you get the number seen on the SGii. Choose the Relative Throttle and you see 0% at idle and 100% when you bury the pedal (or at least I think so - I haven't given the Chevy a Brooklyn Tuneup in a very long time). The UG also has "Throttle Position Commanded" and "Accelerator Pedal Position" gages, but they're about as useful as the "Cat Bank Temp" displays.

TPS is technically more accurate in terms of it being an absolute value relative to a closed throttle and stalled engine. The Relative Throttle will show 0% at idle, even as the throttle is opened to compensate for additional drag from the A/C compressor or power steering pump.

I have an original Scangauge I that I purchased 4 or 5 years ago and I have always had trouble reading the thing in bright light conditions which is why I initially purchased an Ultragauge for my new FEH.
I also purchased one of the new Scangauge II simply because of the Xgauge capabilities.

In my opinion the Ultragauge is easier to use (and see).
I have my Ultragauge on the windshield suction cup mount just above the left side of dashboard and I NEVER have any problem reading it.
When I received my new Scangauge II, I initially mounted it above my rear view mirror
but had to move it down low on the shift console simply because I could not read it in bright light.
