CleanMPG Reviews the ScanGauge II

Not a whole lot to add. It's a great value for what it can do!

Best features:
- current values of WT, RPM, MPG (use these constantly)
- trip MPG (of course )
- "TODAY" MPG
- not turning off on ICE-off (i.e. "hybrid mode")

Things I would like to see:
- Data logging!!! (1-sec values of at least MPH, MPG, RPM, and WT for starters)
- IMPG/Trip MPG on the same screen
- Minimum WT on trip data screens (max is stored, but not min)
- tenths for Trip MPG > 100

Things I haven't used (yet?):
- Diagnostic code reader
- Fuel remaining (i.e. calibrating to tank size and actual fill-up)

I am interested in buying one but notice that next to the buy button it says "Orders will be shiped when enough people have pre-paid".

If I order today when will it ship? Is this a cleanmpg.com discount price or something.

Thanks, Steven

Great comments everybody. I too would love the data logging.

One little thing I like about the SGII:

When highway driving, I keep the FCD on the consumption display so that I can track iMPG, 5 minute intervals, and tank average all on the one screen. I don't need the energy screen, since I'm nearly always pulsing.

But when I introduce warp stealth into the mix of tools, the energy screen theoretically becomes necessary because you can both pulse & warp stealth at iMPG above 99.9.

Well, the SGII iMPG tells you what you are doing. If your iMPG is roughly 180 or more, you are warp stealthing. 140ish or less, you are pulsing. I occassionally find myself depressing too hard, watching 180 drop to 140 or less, then backing off and reapplying warp stealth..............all without switching to the energy screen.

I just got my ScanGauge II a few days ago. Nice unit, and I even read the first few pages of the manual before plugging it in. But after a little while with it I wasn't very satisfied with its performance. It would blank out periodically and sometimes wouldn't work at all after I starting the car. Worst of all, although it did show MPG and other useful stats, it only updated about every 30 seconds -- better feedback than waiting until the next fill maybe, but not exactly the real time feedback I was hoping for.

As it turns out, buried in the back of the SGII manual is a short instruction saying that if you have problems with the display not updating properly, you should select MORE -> MORE -> MODE -> PIDS and change the setting from ALL to SUPPORTED. Interestingly, it specifically mentions 1995-1999 Subarus as requiring this setting, and this is the only mention of a specific vehicle in the entire manual. I guess Subaru's first try at SGII must use a slightly nonstandard communication protocol or something. 2000 and later Subarus don't need this setting.

Anyway, I entered that setting last night and it now works flawlessly, with updates every second or two, and the display is on whenever the engine is on. Took some baseline runs with it last night, and I'm pretty sure I can use the information from this thing to get my MPG up over 30.

I'm posting this for the benefit of other 95-99 Subaru owners who might be lurking, since it is buried in the back in the ScanGuage manual, is not very obvious, and is absolutely essential to getting the SGII to work in your car. Also Wayne asked me to post it here as well as in the separate thread I started.

Hi ALL,
I have a 07 Honda Accord 4cyl auto non hybrid...Was wondering if this will work on my vehicle?
Checked the purchase link it did not list my vehicle there.
I average 24 in city 40 on highway with my auto...Did much better on my 05 honda 4cyl manual.. :>)) got tired of clutch in city..

Thanks
Phil

If it has a OBD-II port it should.

I just checked - it works on all 2007 vehicles except Lotus Elise, whatever that is

Hi, Phil! I believe there is someone else on this board with an '07 Auto Accord and I believe that driver has one working just fine.

Neicy, the Lotus Elise is a cool sports car -- you can see a description of one here:

2007 Lotus Elise

Right Lane Cruiser,

Thanks for the link. But I could buy 2 Prii for the price of that, and am not interested in 0-60 in five seconds, thank you very much

I'm not interested in it either. At least not more than, "Gee, look at that!"

Hi Phil:

___Yes, the non-hybrid 7th gen Accord with the I4 and an Auto is compatible with the SG-II. Not a problem in the least other then during a FAS it takes 4 – 5 seconds for the bus to resend data to the unit. This review was written and the pics taken/uploaded while the SG-II resided on my 05 non-hybrid Accord. Notice the gauge layout as it should look very familiar

___Good Luck
