New PIDs are found all the time, so I thought it might be appropriate to update the list again. I'll post what I've collected, and invite others to share their 7.3l PIDs (including OBS).

Critical Note:

Never ever add a gauge while connected with the engine running... no matter who sent the configuration. The data can have an error or a typo in it, so it's best to set up your gauge off-line, then connect to the truck KOEO after everything is set correctly (to the best of your knowledge). No data or the truck freaks out? Delete that gauge (but keep the PID in the list) until it can be resolved. I got bit a few times while playing with the *****, so I felt it best to pass that on. At the time of this writing, I am working on a formula called "High Pressure Oil Index". It will give a reference number that can hint at a problem with fueling.

This is all to say Torque is a tool for all vehicles... it's up to the user to sort out how to use it with each specific vehicle.

Long name:Barometer
Short name: BARO
PID: 221442
Max/Min: 15.0/10.0
Unit: PSI
Equation: ((A*256)+B)*0.03625
Header: C410F1
The Min/Max values above are for realistic altitudes, but those who traverse the Rockies may see lees than 10 PSI (over 10,000 feet). If you do, you can change the Max/Min to 15.0/9.0.

Manifold Absolute Pressure
Short Name: MAP
PID: 221440
Units: PSI
Max/Min: 45.0/0.0
Equation: ((A*256)+B)*0.03625
It is important that this reads the air pressure of your altitude in PSI (same with EBP and BARO) with Key On Engine Off, then it just adds boost to that while running. [LINK]

Manifold Gauge Pressure
Short Name: Boost
PID: 221440
Units: PSI
Max/Min: 30.0/0.0 (stock) 40.0/0.0 (performance)
Equation: (((A*256)+B)*0.03625)-[221442]
"-[221442]" subtracts the Barometric sensor (located on the PCM on some trucks, external on others) reading from the MAP reading - and this gives you just the boost pressure above atmospheric pressure.

Exhaust Back Pressure (Absolute)
Short Name: EBP
PID: 221445
Units: PSI
Max/Min: 55.0/0.0
Equation: ((A*256)+B)*0.03625
It is important that this reads the air pressure of your altitude in PSI (same with MAP and BARO) with Key On Engine Off, then it just adds Exhaust Back Pressure to that with engine running. [LINK]. 53 PSI is sensor limit. Exhaust or boost leaks can make this reading very jumpy during WOT tests.

Exhaust Gauge Pressure
Short Name: EGP
PID: 221445
Units: PSI
Max/Min: 30.0/0.0 (stock) 40.0/0.0 (performance and/or engine braking)
Equation: (((A*256)+B)*0.03625)-[221442]
It takes the Exhaust Back Pressure(PSI) and subtracts the device barometric pressure reading, giving you the backpressure above atmospheric pressure. Exhaust or boost leaks can make this reading very jumpy during WOT tests.

Fuel Injector Pulse Width
Short Name: FIPW
PID: 221410
Units: ms
Max/Min: 6.0/0.0
Equation: ((A*256)+B)*.008
0.6 ms is "Standby", you need at least 1.2 ms for the injector to work, 3 ms is MAX for a running engine, and 6 ms is MAX for a cranking engine.

Injector Control Pressure
Short Name: ICP
PID: 221446
Units: PSI
Max/Min: 3000.0/0.0 (stock) 4000.0/0.0 (modified)
Equation: ((A*256)+B)*.57
**You may see barometric pressure KOEO
500 PSI is minimum before the truck will start, stock idle is about 475 on injectors with stock nozzles, about 2700-2800 is stock MAX, 700 is ICP sensor unplugged idle, and 2200 is ICP sensor unplugged while cranking.

Injector Pressure Regulator (Injector Control Pressure Duty Cycle)
Short Name: IPR
PID: 221434
Units: %
Max/Min: 100.0/0.0
Equation: A*0.39063
60% - 65% MAX (stock), but you don't want to exceed 40% - 50% at WOT. 9% - 12% is idle, with a stable reading - unstable readings here frequently indicate a problem. 14% is ICP sensor unplugged while running, and 31% is ICP sensor unplugged while cranking.

Engine Oil Temperature
Short Name: EOT
PID: 221310
Units: °C
Max/Min: 250.0/0.0
Equation: (((A*256)+B)/100)-40
I run about 180-190 in winter and 190-210 in summer (empty). For those still equipped with EPBVs, it can activate up to about 145-150 degrees F - it is best go easy on the throttle (on all 7.3Ls) until you get your EOT above that point. You may hear the injectors act "a little odd" as the EOT passes through 100 degrees F. For those wanting the Engine Coolant Temperature (ECT), get a separate gauge or handheld infrared/laser thermometer. You will not find it on the OBDII port.

Torque Converter Slip
Short Name: Slip
PID: 2211b8
Units: RPM
Max/Min: Max 1000.0/0.0 **
Equation: ((A*256)+B)/4
**I use this max to watch idle in gear. Torque Converter will not lock until Transmission Temp exceeds about 50 - 60 degrees F, you are in Drive, and moving at least 35 MPH (Torque Converter Lock Up - depending on your tune and conditions).

Transmission Gear
Short Name: Gear
PID: 2211b3
Units: Gear
Max/Min: 4/0
Equation: A/2
Pretty basic stuff here.

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.

A trinket from Pikachu for 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*
.

 

Thanks for the re-post! I've recently purchased a small tablet and purchased torque pro but have not set the parameters for all of the displays yet. Great info!

 

Methinks a digit is afoul?

 

Thanks again for your efforts Tugly! I will look the list over more closely after RRE and maybe add some OBS formulas.


No, its the same PID, just a different formula.

 

Yup... pick the one you like. No point in having both at the same time, it's the same output, but one does the altitude math for you.

 

Ah so! Thanks!

 

Accelerator Pedal Position custom PID is commonly coded as follows:

OBD2 Mode and PID: [blank]
Long Name: Accelerator Pedal Position
Short Name: Accel Ped %
Minimum Value: 0
Maximum Value: 100
Scale Factor: x1
Unit Type: %
Equation: [11]
OBD Header to Use: [blank]
Diagnostic Start Command: [blank]
Diagnostic Stop Command: [blank]

That noted, I only get a reported 0% value on my device. I believe my issue is device specific as the formula works on my old Android device.

 

That equation confuses me, there should be some references and/or some math in there. Maybe somebody can try it out, as I am unsure when I will have time to tinker. I would offer up the alternate name "Throttle Position Sensor" and the short "TPS".

 

It works. I use it myself.

 

When the OBD2 Mode and PID field is left blank, the torque program references an "internal PID". Not sure what that is.

 

I believe that is a default PID reported to Torque during a scan of the PCM. Some of the PIDs have to be specified, because Torque can't find them, or read them accurately - hence the list provided here. Many basic PIDs are default (part of the generic OBDII requirement by law), and almost any OBDII app should read them without further input from the user. Vehicle Speed and Engine RPMs are good examples of these default PIDs.

 

My truck seems to hate this formula for some reason? I used the formula you had on your other PID post and it would cut the engine out. So I tried this one and gave it a shot again.

Worked great the first time I added it but after that when I start the truck it makes the engine cut out dropping rpms to around 250 the jumps to idle then shuts it off or does it again. Does the formula work for you?

Do you think the protocol it connects to the ecm with matters? I dont even know what all the protocols are for I just use the fast search option on TP.

 

I had a problem like that with the EOT PID soon after I bought my Android system. It worked before it stopped working. Being stubborn and wanting that EOT PID, I stripped My Nexus 7 (2013) of Torque Pro, did all my Android updates, re-installed Torque Pro, and manually programmed all my settings again. The problem disappeared and never came back - I now have my EOT PID again.

Thanks for this, I'll go through my DB and check everything out.
