FWIU it's gearbox oil temperature.

Shame, it would be awesome to get the rear clutch pack temp, there is a sensor there and if that canchecked screen can provide rear diff temps, it's just a matter of time till someone finds the way!

I got my hands on Techstream application which is able to read all of the sensors from GRY. So now we are able to sniff the CAN requests and responses which Techstream is sending and receiving when querying a certain sensor. Figuring out the formulas still takes a bit of time, but we will get there at least for the most interesting values.

I have updated the first post with the formula for the Steering Angle sensor.

Maybe it's time to change your setup... .

Have a look at AAAD and Screen2auto (for non-rooted devices). I can't test it - have got only rooted Android devices - but my rooted setup works without problems.

Bye for now Fred

Could you share your settings file for easy import into torque app? This looks perfect

First post updated with some more temperature sensors.

1. Tire air temperature. At least the OEM TPMS sensors report not only tire pressure, but also air temperature inside the tire. Now we can get these values via OBDII. Note that the sensor list in the first post changed how it identifies which sensor belongs to which tire. I've added PIDs like Tire ID x Position which return the name of the tire (Front Left, Front Right, Rear Left, Rear Right) that the TPMS sensor with ID x belongs to.

2. Master Cylinder Sensor Temperature. Found this sensor under the Brake section in Techstream. Will be interesting to see how this value changes under some extensive hard braking. I've got around 50°C while idling.

3. Temperature Sensor Value in Coupling. Found this one under the Four Wheel Drive section in Techstream. My guess is that this sensor is in the hydraulic coupling that controls Front/Rear torque distribution. Unfortunately I was not able to figure out the exact formula just yet. I see that the interesting values were in A and B bytes. Here is what I saw while idling:

A	B	Value in Techstream
11	B8	35.56
11	D7	35.67
11	E7	35.80

I was not able to find any more temperature sensors in Techstream. I was not even able to locate some of the sensors that we already know from other sources, like Engine Oil and Transmission Oil temperature. That gives me hope that there are some more hidden goodies in Techstream yet to be found out.

Good stuff, worked out the formula for the coupling.
=((A*256)+B)/128

Work in progress, but you asked in a way I couldn't resist... .
Import the zip to Android/data, rename org.prowl.torque and then expand the zip. After starting torque pro (must be pro version) you'll be ready to go.
Layouts marked with CB are 800*480, Power5 is 720*1600, Blackview is 1080*2300. Have fun.

Any recommendation for an iOS app? "Car Scanner" does not display any of these custom PIDs.

That's a key one to know when on track…

Great, thanks so much for sharing, will test it soon.

In terms of adding the user defined PID, on its range, by default is 0 to 100 (in the app I use, at least). Should I change that to say 200? I.e if that formula measures temperature, and if that goes over 100, it wouldn't measure it correctly if the range is set between 0 to 100, unless you change the default range?

I use OBD fusion. Works with a Carista OBD adapter, but I probably paid some money for it. It also allows you to use custom defined PIDs

Does anyone have the coupling temperature working? That pid doesn’t seem to return any data in obd fusion

Nice one! I recorded more data via Techstream and compared with the received bytes passed through your formula. Values seem to match up! Updated the first post.

range, by default is 0 to 100 (in the app I use, at least). Should I change that to say 200?

I think the range only matter visually. It helps the app to show better widgets.

Never used OBD Fusion with custom PIDs, but it should work the same. The parameters on the OBD Fusion app then would be:
Module/Header: 7B1
OBD Mode: 221
PID Number: 026

Ok, Car Scanner works, you have to remove the "0x..." and pay for the pro version. ?

Sadly, the Car Sanner built-in engine oil temperature displays values only up to 100 Deg Celsius. What's the (custom) PID for engine oil temperature?

I am trying new pid in carscanner Pro too.
Everything works with tire pressure and temp.
I have no display for tire position
Do you have tricks?

And also
My one built in oil temp in carscanner works over 100 C Degrees. Maybe scale?

I cannot get tire temp to work.
Which connection profile are you using?

if u mean carscanner pro
i am using normal bt connection with obdlink mx+
nothing different from other pid

but it seems that "lookup" is present only in torquepro, so no chance

 

[dvim]

"lookup" is present only in torquepro, so no chance

Lookup just translates from one value to another. GRY returns tire positions as numbers from 1 to 4. Lookup function translates these values to string representation which is easy to understand for humams: FL, FR, RL, RR.

Any news on a new version / hacking guide?

yes i know but
- carscanner and obdlink/fusion seems to have not this LOOKUP function
- i have imported the csv in torquepro and tire temp and pressure works but i have no translation ftom tireposition
any help on this in torquepro ?
