Has anyone been able to add the air to fuel ratio gauge on xgauge?

Thinking about getting one, found this info and thought I'd share this here:

^Interesting installation.
I was thinking of trying something using the same "velcro" strips that the Illinois tollway
gives out to mount the I-Pass.
How hard is it to route the cable under the headliner?
Do you have any pics looking back into the windshield to see the back side of the install?

toy_toronto · 05-01-2011, 07:37 PM

Sorry I don't have any pics looking from behind that's why I drew up the sketch of the mount. You can't tell it's there looking from the outside due to the tint on the (upper) windshield. It's not difficult to hide the wire under the headliner, just tuck it in under there.

I actually used the same velcro/fasteners they give you to mount your EZ pass or Transponder toll devices to your windshield.

From my pictures above you could actually see two other velcro/3m dual lock strips (right behind the ScanGauge) where I stick my transponder to.

Now that you mention it, I do see the strips of velcro.
Illinois wants theirs mounted lower and more toward the driver's side,
IIRC. I mounted it more centered and below the tint, so it actually
sits behind the mirror and isn't seen by me unless I crank my head a little.

Thanks for the info and ideas!

Got mine last night. Did the basic setup, have not adjusted the cut off setting, have not filled up. This morning I checked what I could on my drive to work. The speed readout was about 1.5 mph below the read out on my GPS, pretty close. The instant MPG reading seemed pretty close to the Eco-meter built into the car. The average for the trip was a little higher than the eco-meter. The SCII indicated 53 mpg avg, the Toyota Eco-meter indicated 51 MPG. I guess as I dial it in it should get more accurate.
I have mine set to fast updating, and I find it easy to watch.

Anyone know if the scangauge can display knock retard values?

jambo101 · 03-31-2014, 10:18 AM

As an instrument to measure MPG my Scangauge is useless and cant be trusted to give an accurate reading..

With a full tank of gas and sitting at the gas station I put in all the required parameters for setup in miles and gallons as the trip was entirely in the USA,also included an Xgauge setting to show me average MPG per day,went to the fillup and pressed DONE then off for a 2000 mile trip,MPG read steady at around 36MPG through the first tankful but when i refilled the tank with 8 gallons of fuel going to the fillup icon it said i just put 12 gallons in so i adjusted/recalibrated the 12 gallons back to 8 gallons and started off again but now the MPG reading was reading a steady 25MPG.Throughout the trip the amount of gas i actually put in got further and further away from reality and i saw fluctuations as low as a steady 10MPG to as high as 90MPG

The problem was probably my my fault but i cant figure out what i was doing wrong as the set up is quite straight forward and subsequent fillups should have read very close to the amount i was actually putting in the tank but in reality that fillup number just got further away from actual gas input..

Any one got an idea whats going wrong?
And can anyone suggest a less problematic MPG device?

Thanks

The problem with how devices like ScanGauge, Ecometer, etc. calculate MPG is what they do when the car is standing still. If the car was always in motion it is very accurate, but as the ratio of in to not in motion increases it becomes a crap shoot.

As for the 10MPG to 90MPG fluctuations; That is actually normal. When the Yaris is under heavy load the MPGs decrease significantly. For example, driving up the 1/2 mile hill of the road that I live off of, I see a pretty steady 8-12 MPG. Coming down it I start off in the 80-90 MPG range (when my foot is still on the pedal) and I quickly hit DFCO where the scangauge shows 9999.

How DFCO is handled is probably another issue with how these devices do their calculations as well. You have infinite MPG during this period, so depending on how you average that in can skew things quite a bit in the opposite direction of averaging the theoretical 0 MPG while stopped.

The only time my ScanGaugeII hasn't been very accurate was the first tank or two before setting it up. After that, it has been within 1mpg accurate on every tank. Maybe you got a faulty device, but I don't know.

A lot of people also love the UltraGauge, and it's less than half the price of a ScanGauge.

I don't have any experience with an UltraGauge, so I can't tell you if it is any better or not. I do love my ScanGaugeII though.

Hi, ScanGauge it's compatible for JDM Vitz RS 2005 ncp91-AHMVK?
Es compatible con ese modelo?

pribek · 02-01-2017, 01:18 PM

Yes it is.
