The truck was cold, the ICP could be that temp because of it, couldn't it?
Here's another screens shot from today sitting at idle all warmed up. I should've had the EGP instead of the EBP. It was -10 below in Chicago today that's why the EOT and TFT is far from each other. Just figured out how to setup the logging too, had it all wrong at first , learning little by little about this app.
AHA! Your EBP is either plugged or shot. I'm leaning toward shot - that is the max reading on the EBP sensor. Your transmission is warmer than I can get mine in the winter.
I have a question that maybe some of you techies can answer. I seem to show about 20-25 degrees too high on transmission temp on my tablet. Is there a way of calibrating the PID to show the right temp?

whats the equation your using, I know over the years its been slightly updated, the Torque Pro FAQ link in my signature SHOULD have the most up to date equation for the trans temp IIRC, and it also makes a good read too
First; Thanks for the quick reply.
Okay I tried to create a new one and instant shut down on test
Here is what I got:
Testing PID
Result for equation: [No response]
Command 221674
No response
Here is what I had in each field: OBD2 Mode and PID
221674
Long name:
Transmission Fluid Temperature 2016
Short name:
TFT
Minimum value:
0.0
Maximum value:
250.0
Scale factor:
x1
Unit type
F
Equation:
((A*256)+B)/8
OBD Header to use:
Blank
Diagnostic start command
Blank
Diagnostic stop command
Blank
I am sure it is something dummy me is doing as I don't really understand it.

Ideas?
What year is your truck? If its a L99 or later use the RED one If it is a E99 or before (OBS) use the GREEN one your long name may be whats throwing things off also, just drop the numbers also IIRC obd2 mode and PID number should be seperate entries, the mode can be left blank or auto
Transmission Fluid Temperature
Short Name: TFT
PID: 221674
Units: °F
Max/Min: 250.0/0.0
Equation: ((A*256)+B)/8
230 degrees F is the limit, according to the book. It has been mentioned by the forum's resident expert that the transmission doesn't reach optimum efficiency until about 165 degrees F.
OBS and some E99 trucks: Transmission Fluid Temperature
Short Name: TFT
PID: 2211BD
Units: °F
Max/Min: 250.0/0.0
Equation: (((A*256)+B)*-0.0036)+212.98
OBD Header: C410F1
*note the 0.0036 is negative*
I tinkered with renaming some of my PIDs in an attempt to make several similar experiments, but I learned renaming the long name of a PID is bad juju - with very nasty running characteristics as a result. We're stuck with using the factory long name of the PID, but we can run amok with the short name.
Thanks again to both of you. I will try it tomorrow and let you know. I also suspected the long name but have not had a chance to try it yet.
My truck is a 2001 so will use the Red one.
Okay changing the name fixed the Kill problem.
I looked at the stock Powerstroke PID and edited it instead. The only difference I saw was the Maximum Value was at 100 while the one you spec'd is 250. I changed that, tested and it liked it so I deleted the gauge and set it up again. Looks like it is working. Next time I take the truck out for a run, I will see how close the gauge seems now.
I have a laser thermometer, where would be the best place to take tranny oil temp from for comparison?
The temperature difference is probably due to the location of the sensor within the transmission. The pan is going to be the coolest place.
But 20-30 degrees? The top of the oil pan is the hottest thing I can find on my transmission. I hit the Ford Idiot light temp last year on an 18 mile 7% climb pulling our heavy 5th wheel. They say the light comes on at 230, my guage showed 250 when the light came on. This is about consistent with the differences I am seeing from gauge to oil pan.
I don't understand the formula in the PID but I may try messing with it anyway.
