New SGII- What settings do you use?

Set-up is easy. Just take your time. You will be setting it for hybrid mode, 1.5 liter engine size, and 9 or 10 gallon tank depending on your preference. The hardest part for me was finding the OBDII port to plug it into. SOC is one of the x-gauge things you need to program for.

Duh. The settings I use are: RPM SOC
wFT mpg

 

Near your right shin when you are sitting in the drivers seat.

I use RPM, WT, IGN, GPH.

I don't see many people discussing GPH, but I am convinced this may be the best feedback of all. It is somewhat redundant because it is fuel flow per unit time and you already have Instantaneous MPG from the MFD. However, it has an interesting math relationship to iMPG: MPH / MPG = GPH

Jimbo has his theory that the acceleration rate should be so that the iMPG is about 1/2 of MPH on the speedo - this is GPH = 2. I find it pretty easy to accelerate and keep GPH between 1.8 and 2.

Hobbit has talked about 60 MPG @ 60 MPH -> GPH = 1 I am able to hold GPH = .5 @ 50MPH -> iMPG = 100 mph on the flat parts of my commute subject to wind, traffic, etc.

The combination of RPM, IGN and GPH let me know when I am in stealth mode -> RPM = 0, IGN = 5, GPH = 0 (sometimes 0.01 but I believe this is roundoff error) Warp Steath is RPM ~ 960, IGN =5, GPH =0.
Super Highway Mode is RPM ~ < 1600, IGN = 14 , GPH ~ .3 - 1.0.

When GPH gets around .2 with low demand, I know it is about to go to WS, so I can adjust to keep GPH @ .3 or a little higher if I want to keep it out of WS.

 

Here is a lot of info in a small space:

Here is the list of XGauge modes, including the specific ones for the Prius:

I use the engine coolant temp and RPMs because I miss those gauges from my last car.

I also use the instantaneous MPG and the MPG for the current trip (which I had to set in xgauge). I prefer the ScanGauge MPG over that of the MFD because ScanGauge MPG goes up to 9999. Having the average FE for the trip right next to the current MPG helps me see if I'm on track to reach my MPG goal for my commute. (I figure I'm doing well if I get ~53 MPG, or about 10% over the EPA estimate.) Those readouts were also accessible in my last car.

I expect that I will tweak these selections as I get to be more conscientious in my driving and learn better how to drive the car for optimum FE.

 

Yes, if you are going 60 mph and holding GPH =1, then the MPG reading on the MFD will be ~60 mpg. Sometimes you can hold this pretty easily, sometimes its harder with crosswinds.

Too bad about the PDF - it downloads and opens for me. It is a one page summary of the five stages of operation, plus short summaries of the different techniques used to maximize mileage.

 

Sorry to show my ignorance but.... what is WT, WS & IGN. Just ordered my scangauge & trying to up my learning curve (not easy for us old farts). TIA

 

WT is Water Temperature - Actually, Engine Coolant Temperature.
The scanguage gives you a choice of fWT (Farenheit) or cWT (Centigrade) depending on how you've set your Units.

IGN is Ignition - Actually, degrees before TDC.
This is, in my opinion, one of the most valuable gauges. It enables you to zero in on Super Highway Mode.

WS is Warp Stealth. This is not a gauge at all but a hibrid operating mode. When speed is above 42mph, only yellow arrows are visible.

Hope that helps.

OK .... so what is TDC and kindly do not use acronyms.

 

TDC = top dead center. see the following link for a good explanation:
Ignition Advance and Speed mapping

 

Has anyone figured out how to read inverter temperature? I've e-mailed Linear Logic, but I haven't received a response.

 

on the left side I've got rpm and horsepower
on the right side speed and mpg

 

Just curious -- I'm about to receive my Scangauge in the mail, and was wondering if there is a quick way to setup multiple profiles. In other words, the ability to switch quickly between two or more displays, each display with a user-programmed 4 gages. Reading all the threads out there about the Scangauge, I think I'm going to want to monitor more than 4 gages quite frequently.

If not possible to set up multiple profiles, then is it possible to connect and use multiple scangauges to the vehicle at the same time, perhaps by using a cable splitter? From pictures, it looks like the Scangauge uses either an RJ-11 or RJ-45. The only concern I would have is that the CAN bus supplying the power and signal through the OBD2 connector could be damaged with the slightly greater current draw of 2 scangauges. Has anyone experimented with this, or have knowledge of the current draw of the Scangauge and the current limitations of the CAN bus?

 

Great question! I doubt if its standardized computer network communications. If it were, you could install a 5-port network hub and have 2 in front, and one on the back of each front seat for the rear passengers to look at!

 

I might end up buying a 2nd Scangauge for my other vehicle. If I do, I suppose I could experiment with connecting 2 Scangauges to one OBD2 outlet, using a splitter.

Any electrical-techies out there, please chime in if you think I shouldn't attempt this. I wouldn't want to damage the CAN bus circuitry.

Years ago when I was installing network data ports in my new house (CAT5 / RJ-45), I fabricated 2 simple devices, 1 male, 1 female, to test the continuity of my connections and wiring. I could resurrect those to install in-line with my Scangauge to determine how much current each wire draws. I suspect the signal wires will be almost nil, and the power wires will indicate some fraction of an amp. If any of you have already done this, please share your knowledge. Thanks!
