GR Yaris PIDs reverse engineered revisited

Yes, I have both diagnostic start and stop commands. Looks like, I need a better OBD device like yours.

I bought an OBDLink LX after trying two vLinker devices; with those two devices, I was never able to display tyre data using Torque, although various other apps worked. With the OBDLink LX, everything now works and I can also use AATorque on the multimedia display for this data.
 
Does anyone have any data of their Knock Correction Learned Value? Mine is around 21-24 most of the time and drops to about 18.5 under hard acceleration, just wanted to check if that was normal

Mine never goes below 23, usually sits at 24.1, even after a hard drive or a track day...
I am using OMV or Shell V-Power 100 octane fuel since day one (now at 102k km)
To the best of my knowledge those number indicate timing is retarded during hard accel, so a better quality fuel should give you some more power... I would suggest to log rpm, timing advance and knock feedback value to have a better picture...
 
Mine stays around 23-24 as well. There have been a few times when it dropped into the 22s, maybe bad batch of fuel. I'm running Neste 98.
18.5 seems on the low side. Are you running the stock map?
 
Try this:

Wastegate Valve Control Duty Ratio
OBD2 Mode and PID: 221F72
Long name: Wastegate Valve Control Duty Ratio
Short name: WG Duty
Minimum value: 0
Maximum value: 100
Scale factor: x1
Unit type: %
Equation: B*0.3921568627
OBD header: 700

Not sure it it works on GRY, but it will not cause any problems requesting this PID.
If it works - let us know ;)

I believe I've found the actual wastegate duty signal.
Funny thing is - it's not visible in the Techstream (GTS) ;)

Wastegate Valve Control Duty Ratio
OBD2 Mode and PID: 22282B
Long name: Wastegate Valve Control Duty Ratio
Short name: WGV Duty
Minimum value: 0
Maximum value: 100
Scale factor: x1
Unit type: %
Equation: ((A*256)+B)*0.006103515625
OBD header: 700

Thanks.
I have put it in Torque Pro.
What do the shown Values mean?
The percentage opening of the valve? 100% full open or full close?

Max Value at full throttle was 88%

Bravo!
So we finally have the WGDC!

0% fully open, 100% fully closed
Apparently it caps at ~20% - 88% for practical reasons (e.g. protection from slamming the valve against its seat...)
