More PIDs for Torque App

[AmpOverload]

I might not have the answer today, but I will figure things out soon. Give me a day or two because things are a bit hectic here at the moment.

OK, I've run some tests with GDS2, now using your anonymized (2013) VIN instead of specifying a 2012 vehicle, but still specifying the 'LUJ' engine. The change in model year caused the list of Mode $22 PIDs being queried for the "Engine Data" page to change. It's now this list of 54 PIDs:

$0004, $0005, $0006, $0007, $000B, $000C, $000D, $000E, $000F, $0010,
$001F, $002E, $002F, $0030, $0031, $0033, $0042, $0044, $0046, $1123,
$1124, $1127, $1128, $1130, $1131, $1190, $11C9, $1232, $1233, $12B1,
$12C3, $131F, $136C, $148D, $1523, $2006, $2020, $203F, $205A, $2067,
$2070, $2072, $207E, $20D0, $20D4, $20EE, $2301, $2320, $2321, $247D,
$3201, $328B, $328D, $3298

Here is the information I decoded for each of the 6 PIDs you were interested in:

1. 'Boost Pressure Sensor', Mode $22, PID $3298, formula "(A * 256 + B) / 100" in kPa
2. 'Turbocharger Bypass Solenoid Valve Command', Mode $22, PID $328D, formula "A / 255 * 100" in percent
3. 'Turbocharger Wastegate Solenoid Valve Command', Mode $22, PID $328B, formula "A / 255 * 100" in percent
4. 'Fuel Economy', Mode $22, PID $203F, formula "A / 2" in liters per hour
5. 'BARO' is just the standard Mode $01 PID $33 (defined by SAE J1979). The formula is "A" in kPa.
6. 'EVAP Purge Solenoid Valve Command' is just the standard Mode $01 PID $2E (defined by SAE J1979). The formula is "A / 255 * 100" in percent.

The only thing I ask is that you let us know how well (or poorly) those PIDs work.

Good luck!

Hello,
I had to take a ride anyway so I plugged in my favourite ELM327 tool. The results:

• Boost Pressure Sensor - works, values seems to be ok
• Turbocharger Bypass Solenoid Valve Command: works
• Turbocharger Wastegate Solenoid Valve Command: works, it's either 0% or 100% (makes sense)
• Fuel Economy: works, the problem is the resolution; obviously it's 0.5 liters per hour. E.g. if the dash shows 0.7 liters, Torque still shows 0.5. But it works.
• BARO: Nope. It constantly shows 190kPa, should be ~100 kPa. Maybe I added it wrongly? I added custom pid '010033'
• EVAP Purge Solenoid Valve Command: I'm not sure. I also added '01002e', it shows always 74.5% but when I stop the engine I know from experience that the Evap valve is closed, so it should be 0% or 100%, it depends.

Here is the csv list so far:

"Name", "ShortName", "ModeAndPID", "Equation", "Min Value", "Max Value", "Units", "Header", "startDiagnostic", "stopDiagnostic", "scale","minimumRefreshDelayMillis"

"[A14NET] Boost Pressure Sensor","Boost","0x223298","((A*256)+B)/100",0,656,"kPa","","","",1,0
"[A14NET] EVAP Purge Solenoid Valve Command","EVAP","0x01002e","(A/255)*100",0,100,"%","","","",1,0
"[A14NET] Fuel Economy","Fuel","0x22203f","A/2",0,100,"L/h","","","",1,0

Sorry, I neglected to mention something about Mode $01 versus Mode $22...

Mode $01 PIDs are only 2 (hex) digits. So, for a Mode $01 PID like 'BARO', use a command of "0133" or use the Mode $22 (4-hex-digit) equivalent command of "220033" (and maybe with a trailing "01" since GM sometimes requires that on Mode $22 queries, assuming Torque Pro doesn't add it automatically for you). Same thing for the EVAP Purge PID.

Let us know it if that helps. Good luck!

P.S. I'll take another look at the "Fuel Economy" PID, in case I missed something, like maybe a 2nd byte, to provide higher resolution.

OK, I just double-checked the "Fuel Economy" PID. Unfortunately, I see no evidence that there is any higher resolution available there (i.e. a 2-byte PID instead of a 1-byte PID). I cannot explain why your dash shows greater resolution.

Hello,
never mind, I'll keep it anyway for fun. In the meantime I tested the two standard pids (baro & evap) by correctly enter the pid number - both works! When the Evap valve is closed, the value is 0% (it shows how open the valve).
Thank you very much, these are really useful! Also your method to find the correct pids and calculations works perfectly!
