Driving home after work- a short drive of just over 4 miles--my vehicle finally went into electric mode (about 2 miles into the drive) when the water temperature hit 155 degrees despite a 54.something SOC reading on the scangauge. It remained in electric mode until the water temperature dropped to 123 degrees despite a SOC reading of 42.2. The temperature has dropped today and was approximately 34-35 degrees with a brisk wind and frosty flakes.

Time to install the cardboard radiator wind block until someone can find something better.

Posting this information as a means of sharing data that our new Scangauge units can display. I wonder if this site should have a "place" where we could post photos and comments on the various Scangauge "readouts" we obtain from our day to day driving experiences.

 

Sounds like a good idea to me.

What I'm positive of is:
In a 2005, a water temperature of 140'F is required to enter EV for the first time. Once in EV, you can drive EV down to a water temp of 125'F.

The SG monitors the temperature sensor about once per second.
However, the FEH itself, either monitors more slowly, or takes a 10 second average into account before deciding to turn the engine off or on.

Thus, you may see your SG at 140'F or higher a few moments before the ICE actually shuts down, and you may see your SG at 125'F or lower a few moments before the ICE kicks back on.

The true parameter specification is 125'F and 140'F, but the FEH does not "see" those temps at the exact same moment as the SG. They are pretty darn close in most cases though!

This A.M. I figured my Block Heater used 10 cents of electricity, but going EV right away on a 35 degree day saved me 35 cents of gas based on my last fill @ $3.16. That was 9.8 miles to work BTW.

So.... after 7000 miles ( 700 trips to work ) my block heater will have paid for itself!

Saving $0.25 a day on gas is not much, but it's still kind of fun to keep my MPG above 40 MPG in winter!

Carl, following your numbers exactly, MiT and GiT both display 0.0 with the engine running on a 50'F day.

Also, Motor Coil Temp, and Generator Coil temp are reading something, but not degrees F.

I get 25.5 to 28.5 for Coil temps with engine running on a 50'F day.

*The MTH part looks unusual to me.
That's what you put on PID's for AMPs.

 

Just testing you.....For the Temps, the MTH should be 001200010140

The explanation: temps are in C multiply by 18 (0012), divide by 1 (0001), and add 320 (0140), then divide result by 10 (8 in RXF) to get a tenths reading in F.

Also, for the inverter temps, they are 2-bytes long so RXD should be 3010, not 3008.

Gotta stop posting without double checking....

 

Hey Carl, you watch my back, I'll watch yours....

I want to plug my SGI into my SGIIxG.

I know how to physically do this.
Both versions use 8 wires, but the wire colors have changed over the years. The OBDII connector on the SGI simply unscrews. I was going to solder or crimp on an RJ45 connector.

Old SGI wires are Green, Purple, Yellow, Red, Blue, Black, Orange, Gray.
The black is ground, but that's all I know.

My SGIIxG has Brown, Brown Stripe, Green, Green Stripe, Blue, Blue Stripe, Orange, Orange Stripe ( not in that order ).

Any idea what each wire does so I can connect Tx to Tx?
I'm pretty good with trial and error, but would like to avoid the error part.

I called Joey at LL and he didn't know off hand and was going to ask Ron.
I'm going to have to sit at work and do nothing but wait and receive a big shipment tomorrow, so this is something I could really work on and get done tomorrow. TIA. I'll try the "revised" motor codes on the drive home.

Since there are ( at least ) 3 versions of ScanGauge out there, may I suggest for future reference:

SGI = Original, big box with amber screen

SGII = ScanGaugeII, compact, color screen, removable cable

SGIIxG = ScanGaugeII with xGauge

( and for GaryG that is capital "eye eye" not one-one! )

 

I would propose the scangauge equipped with xgauge would be just called SGII+

Or in my case SGII+-SoC

 

I would rather go Scangauge I, Scangauge II, Scangauge III.

 

Billy, did you try the 4WD indicator xgauge? I have no way of testing it and was wondering if it worked.

 

It works perfectly. Look in the recent thread of 29.5 SOC.
