ScanGaugeII work on 2010?

Adrian,

I finally got around to programming the two fuel XGauges, the fuel in uL and in uS. Both of these appear to be linked to the engine RPM where when the RPM goes to zero these gauges freeze at last state. Is this normal? When I restart the car they immediately return to zero.

How do you tell when the engine is spinning but not using fuel, when these values freeze or drop to some minimum value?

Any more info on the scaling of these signals?

Thanks,

Dwight

 

After reading this thread (and many others), my eyes are blurry. I just got my ScanGauge II from Amazon for $118. It is running firmware v4.06. I have two newbie questions (so far) that I could not figure out answers to.

1. A gen 3 Prius has a fuel tank capacity of 11.9 gallons. According the the ScanGauge manual, one should round DOWN the capacity to the next whole value. Is everyone using 11 gallons as the capacity?

2. I looked at the spreadsheet for XGauges but could not find an entry for displaying the much mentioned stages of the HSD such as S0, S1a, S1b, S2, S3, and S4. How are people determine this?

Thanks and regards, Peter

 

I programmed mine for 11 gallons.

 

11 it is then!

 

1. I went the other way and programmed mine for 12 since it was 11.9. Mine is usually dead on the gallons used for fillup so I do not see where it makes a difference.

2. I monitor the engine coolant temp to determine the warmup stage.

 

I am going to stick with 11 for the next couple of tanks and then try 12 and see what (if any) difference it makes.

I've got the water temp gauge on and am monitoring it. At this point I am getting into information overload and spending too much time staring at the gauges rather than the road!

Thanks and regards, Peter

 

LOL - I think we all go through that when we first get the SGII ! There is a lot of info available to add to overload.

 

Hi Dwight,

yes,please let us know, i want one

 

Vincent,

I am out of town and away from my Prius right now. When I get back in town I will begin trying out some of your new PID's.

Thanks,

Dwight

 

Hi All,

I'm a newby here.

I just got a Scangauge II for Christmas. In just 5 minutes, I was able to set the back up beep to a single beep and the seatbelt beep is disabled in our 2012 V. I called some local Toyota dealers and was quoted anything from a flat fee of $51 (I'm guessing about a half hour labor) to a minimum of one hour shop labor. The Scangauge almost paid for itself in just 5 minutes!

FWIW... my Scangauge II came with firmware 4.06 out of the box.

The Scangauge II along with Adrian Black's spreadsheet rock!

Al
Gig Harbor, WA
2012 Prius V - got it a little over a month ago.

 

I'm somewhat puzzled by this Xgauge. I want to display kW instead of amps. Scaling with 0.22 (ie assume 220 V) is good enough for me. However, when I tried adjusting the multiplier and divider, the decimal dot disappeared. I thought the "8" i Offset 2 was supposed to always add a dot? I also don't quite understand the logic behind subtracting F334 = 3276?

In general, I think there are much information missing from the Xgauge coding manual. For example, is the division signed or unsigned? I also wonder if anybody knows how to decode 16-bit little endian values. Seems impossible to me.

 

Vincent,

I just tried i1s, i1f, i2s, i2f, cvd, wpd, cvs, cvf, and Vlo. All blanks. I double-checked and triple-checked the parameters to make sure I was not making a mistake.

I will try the remaining PID's tomorrow and let you know.

Dwight

 

Oops! I'm sorry, it was my mistake. I sent it to the wrong ECU.

Hi astrand,

Yes, the "8" will add a dot if the results are between -99.9 and 99.9 inclusive. Otherwise, it will drop the dot, e.g. 100, only 3 digits will be displayed. Therefore, you need to re-adjust the multiplier and divider so that it falls within the range.

From the Repair Manual, HV battery current has the following range:

Min.: -327.68 A, Max.: 327.67 A

Using y = Mx + C,
When x = 0, y = -327.68 => C = -327.68
When x = 65535, y = 327.67
327.67 = M * 65535 - 327.68 => M = 1 / 100

y = x / 100 - 327.68

To display 1 decimal point, the result must be 10 times.

10 * y = x / 10 - 3276.8

So, your multiplier & divider is 0001000A and offset is F333 or F334.

I agree. The division is unsigned in firmware 3.17. I don't know about FW 4.0x and higher. I think it is 16-bit Big-endian.

Vincent,

No problem. Let me check these new parameters and get back with you.

Thanks,

Dwight

 

Vincent,

It works much better with the correct ECU

All PID's worked but I did get a few unexpected replies.

Water Pump Run Control Duty, wpd, returned 3.9% instead of your listed range of 62.5 to 81.3%. I was sitting in Park but pressed the accelerator and revved the ICE and still no change. I will have to try this one again while driving.

Number of battery blocks, num, returned a 0 instead of 1 thru 14.

SOC Min, Slo, remained at 0.0% while driving and when start and stop. I even ran in EV mode for a short while to try to pull HV battery down to see if it took a minimum SOC before recording and still remained 0.0%. Will have to continue monitoring this one.

Battery Block min and max voltages and block number for min and max move around a lot. I would think this is good news that the Battery Monitoring system is working well to keep the battery blocks equalized.

Keep working on this PID map and maybe we can fill in all of the blanks !

Thanks,

Dwight

 

Vincent,

In your last group of PID parameters you used an RXF of 02EAX4610578 for the first half and 010702EA0321 for the
second half.

Is there a "simple" explanation as to why you used one versus the other?

Thanks,

Dwight

 

02EAX4610578 - First Frame msg.
010702EA0321 - Consecutive Frame msg.

Pls refer back to this post for the explanation of FF and CF.

CF do not have the PID (78 in this case) in it, so we need to make use of the Sequence Code (21 in this case) to filter out the responses.

You can read up the ELM document (Pg 40 ~ 42) to learn more.

Vincent

 

Vincent,

As always, thanks for your explanation. I went back and reread your explanations of First Frame messages and Consecutive Frame messages.

Dwight
