New SGII- What settings do you use?

[Sheepdog]

Hi all. Intimidated is the word. I will set it up tomorrow hopefully. But not sure about setting for daily use. Does the gauge start off with settings for mpg, soc, rpm etc already? I will be reading the manual tonight after getting home (RTFM!) just hoping for any hints I need that I might miss.

Thanks

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

Thats a great first step idea. Where is the darned connector?!

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.

wow Dogfriend, Thats a lot of info in a small space! It is gonna take me a bit to internalize and be able to use info like that on the fly. If it werent for forums like this would anyone ever know all this I wonder?

Thanks.

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

I've seen exactly the values you list for stealth. cool. If I understand Hobbits 60/60 gph=1 all I have to do is keep the gph at 1 or less while at 60mph and I get 60 mpg? I will try that.

The KB above opens to an empty pdf for me. drat.

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.
