Unfortunately, the SG has to use the MAP sensor manifold vacuum data that the computer makes available through its diagnostic port. No data as to how much actual fuel is used appears to be available, and the SG is left guestimating with the limited data it gets.
People are reporting having to calibrate it over and over and it still remains off. Switching from highway and city driving also throws it off.
Unless someone proves me otherwise, this gadget is bogus.
have you used one yet? I manually calculate ever tank I burn and it is always within .5 MPG accurate. Also when it says I have 30 miles left on a tank, I wont be driving 31, its that accurate. the only bad part is the HP/torque readings because they are not rear wheel readings. but for everything else its awesome!
So that'd be an about 1 to 2% accuracy for you. I've seen another one claiming 3%. I have also seen another one claiming "wildly inaccuracy" of 50% sometimes, when changing the driving habits between city/highway ratio.
The problem is that the scangauge has to use MAF/MAP data, and does not have access to fuel injector data from the computer.
It's really just voodoo guessing, and the scangauge just can not be used to accurately determine real time mpg.
thats in PWM-coded vehicles. Mine is the Ford CAN-OBII which does read the fuel rate. also displays fuel pressure, pph reading, etc.
get one and use it before you bash it. and you can type all you want, It's not like your paragraphs are going to make me sell it or anything. its staying right where it is. topic closed
You can call it scamgauge all you want, I was getting a combined 28 mpg in my car until I got my scangauge. It forces you to be more aware of fuel economy and now I get a cool 36 mpgs. And I'm not coasting with the engine off, not drafting, not running stop signs...none of that crap.
28 -> 36... rriigghhtt. What car do you drive again?
I'm still highly doubtful of scangauge because of the way it works - it does not have access to fuel injection data, but has to guestimate by using MAF/MAP data which can't be very stable or accurate.
You know, you're right...I checked the "tank" display for the current tank of gas...I'm only getting 35.6 mpgs. I was stuck in a nice 30 minute traffic jam on wednesday, that dropped my numbers. Sorry to but up such a silly number like 36.
Make no mistake about it, the scangauge doesn't physically increase your mpgs. What it does is force you to become a more efficient driver.
I'd like to comment on this..."wildly inaccurate". To the untrained eye, yes. When you're driving and the the MPGs are all over the place, that's because they are. When you're doing 40 on a flat surface giving it steady gas, you'll get maybe 38 MPGs, when you let off the gas it will shoot up to around 160. When you want to accelerate up to 50, the MPGs will drop to 20 something. Yes, it's erratic, but so is your fuel consumption while you're driving. It constantly varies.
That's not a wildly inaccurate I was referring to. Someone reported that once calibrated, when you change you driving habit and city/hwy mix, it goes way off in some cases.
Problem is it doesn't have accurate fuel injection data, and has no make sue with things like mass airflow and manifold pressure.
The coolest part about this is, the savings in gas will allow you to pay for this gauge in a matter of time.

Does that require batteries or is it powered by the OBD?

powered by the OBD2 port. if the vehicle is competely off, you can press one of the bezel keys and "wake" it up

Thank you, Raptor. That was a pretty good review of the ScanGauge II. You showed me what I wanted to see. Thank you.

The scangauge as far as I know does not use CAN data.
Topic is not closed. I will continue bashing the scamgauge as I see fit.
