ScanGaugeII work on 2010?

Vincent,

You are correct again! I tried the vlt XGauge again and tried both ACC and IGN-ON. It took IGN-ON before the ECU reported the auxilary battery voltage but it did report it at 12.6V versus 12.8V for the VLT XGauge.

So this does work correctly. It appears to be about 0.2-0.3V lower than the VLT. The VLT signal appears to be the correct signal as compared to a DVM.

Did you see my post #478 below and my comments about the three Inverter PID's reporting about 30-40F high compared to Adrian's I1C PID?

Thanks,

Dwight

 

It all depends at which point of the 12V bus you are measuring. If you use your DVM to measure the point close to the ECU, vlt may be more "correct" than VLT.

Yes, I wanted to try the new formula because it fit the min. & max. value of 59°F & 302°F. It seems on the high side. I'll get back to you later.

Vincent

 

Thanks, I will try it too. I'm reading this post and testing your PID's.
Vicent, do you have more setting pid's, like seat belt or reverse beeper Adrian Black's spreadsheet?

Thanks.

 

I have a chance to look at the log file by Techstream, thanks to Paja!

The Inverter Water Pump is showing 3500 rpm. So, if you change the MTH to 000100010000, it should show around 3277-3714 RPM.

I have an idea to test the VMF, CF0 & CFR. You can try Adrian's SFS, Set Battery Cooling Fan Speed, to manually turn on the fan.

Vincent,

I finally figured out that the battery fan motor operates for me after stop and go traffic and then stopping such as for gas. Before stopping for gas the battery temp was about 90F. After filling up and restarting the temp was up to about 96F and the fan was running and I recorded the following:

CF0 = 34%
VMF = 1.4V
BFM = 3 (Adrian's battery fan mode 1 -> 6)

The RM gives the following ranges for the above parameters:

CF0 = 0 to 127.5%
VMF = 0 to 25.5V (Fan Mode 1 = 1.0 to 1.4V)
BFM = 1 -> 6

Since this is a 12V fan the VMF value appears to be low. I am going to have to try Adrian's battery fan mode request XGauge and step it through the modes and record the above parameters.

Dwight

 

Thanks for helping to test.

Your signature shows that you are using Data Logger OBDII Bluetooth Windows Mobile, would you PM your email so that I can send you the spreadsheet for Torque?

Vincent

 

I want to thank those of you who do all the work to discover, test, and publish these. I have downloaded the spreadsheet a couple times and enjoy trying these, observing, and learning. I suspect there are others like me who use and appreciate these X-Gauges as well.

 

For reference, Paja's values are 70.7% ~ 71.3%.

Paja's values are 62.50% consistently. So, the MTH should change to 027100640000.

Vincent

 

DC/DC Converter Duty Pulse : Those are about the values that I remember seeing. Did Paja report that the values changed a lot or not? Mine just seemed to change on power up and not during driving.

Water Pump Run Control Duty - let me try your new MTH and get back with you.

 

Vincent,

I tried your new MTH above for Water Pump Run Control Duty and now read 6.2%. So I changed it to 0271000A0000 to divide by 10 rather than 100 and now read 62.5%.

Once again it is constantly on 62.5% without changing, at least not so far. But now it agrees with Paja

Dwight

 

You are right! I forgot about the 10X factor in RXF.

From his log, the captures only start after power up, so I can't tell whether it changed during that time. His values did not change much during driving. My guess is if you have parked your car for sometime, the Aux. battery SOC may become low and needs to be recharged. The longer you parked, I would expect the higher the duty pulse.

Vincent

 

I stand corrected. Adrian's equation is correct as confirmed by Paja with TS.

Vincent

 

Vincent/Adrian,

I tried Adrian's Set Fan Speed PID today and measured the battery fan mode, CF0 % and VMF voltage today. I came up with the following:

BFM = 1, CF0 = 34% and VMF = 1.3V
BFM = 2, CF0 = 41% and VMF = 2.0V
BFM = 3, CF0 = 48% and VMF = 2.5V
BFM = 4, CF0 = 55% and VMF = 3.0V
BFM = 5, CF0 = 63% and VMF = 3.5V
BFM = 6, CF0 = 72% and VMF = 4.0V

Adrian is right about the fan screaming at mode 6. Putting your hand in front of the rear seat grill and you can really feel the air being drawn by the fan.

Thanks,

Dwight

great you the man!!

 

HV Battery Temperature Observations:

I have been monitoring the HV battery temps, battery fan mode, speed and voltage lately. It has been unseasonably warm in NC lately with low's in the 40's and high's in the high 60's.

I have noticed that driving at highway speeds the battery temps run about 10-15 degrees above the cabin temp or about 80-85F. Once I get in town with stop and go traffic the temp rises to the 90-100F range. Somewhere around 97-98F the battery fan begins to run in mode 1 or about 35% speed.

I have noticed that if I make a short stop such as to fillup with gas, the temp continues to climb with the engine off. When restarting the car and driving again the battery temp is in the 105-110F range and the battery fan is in mode 3 and about 50-60% speed.

I did not think that I have heard the battery fan in the past but the other day with the fan in mode 3 I turned off the radio and stopped the vent fan. The noise that I had thought was from the vent fan was actually the battery fan.

It is going to be interesting this summer when the outside temps reach the 95-100F range and monitoring the battery temps and fan speeds.

 

I have not seen Adrian respond in a little while now. In his absence I will try to answer this for you. The 7100 RPM for MG2 at 60 mph is exactly right.

My guess is that you have studied the power split device for the Gen II. The Gen III uses a MG2 with a higher speed motor than the Gen II and a speed reduction gear. The top speed for the Gen III MG2 is 13500 RPM. So, 7100 RPM at 60 mph is spot on.

I wish someone would convert one of the power split device animated graphics to include the new Gen III motor speeds and gear ratios.

 

Ahh..you are absolutely correct! Thanks. I looked up a later version of the PSD equations and it showed a different (correct) multiplier for Gen III MG2 speed vs ground speed. The nomograph is a bit confusing on this point...
