People are always discovering more stuff, now that Torque is being used by more members. Pikachu made a recent (and very important) discovery, so I wanted to include this in the list - without burying it in the many pages in the previous Torque PID thread.

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 still wrestling with Boost and Exhaust Back Pressure Gauge readings (pressure above atmospheric pressure). 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
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. If you have a barometer in your portable device, you would be better off to take out "[221442]" and insert "BARO()", this will allow you to have Boost and Exhaust Gauge Pressure at the same time.

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 Gauge Pressure
Short Name: EGP
PID: 221445
Units: PSI
Max/Min: 30.0/0.0 (stock) 40.0/0.0
Equation: (((A*256)+B)*0.03625)-BARO ()
This works ONLY if you have an accurate barometer in your portable device. It takes the Exhaust Back Pressure(PSI) and subtracts the device barometric pressure reading, giving you the backpressure above atmospheric pressure. I tried this with my Nexus 7 up to 7500 feet and the tablet did not compensate for altitude, so this will work only at sea level for me.

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 1.0 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 will 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 500.0/0.0
Equation: ((A*256)+B)*0.6103
**I use this max for the sake of spotting slip, but the reading will peg to the right and give a high reading when Torque Converter is not locked. 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 Fluid Temperature
Short Name: TFT
PID: 221674
Units: °F
Max/Min: 250.0/0.0
Equation: ((A*256)+B)/8
Max temps vary, depending on who you talk to... but 210 degrees F to 220 degrees F is the range that makes everybody raise an eyebrow. It has been mentioned by the forum's resident expert that the transmission doesn't reach optimum efficiency until about 165 degrees F.

Another 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*

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

 

I'm working on a formula for getting an altitude reading from the BARO, but it will take some testing before I post it. When I say "working on", that really means "when I have some free time".

 

Keep up the good work, Rich.

 

See how this works for you:

PID: Blank
Equation: -2174.2 * [221442] + 31975.631

I based it on a linear relationship between pressure and altitude even though I believe it's a slight curve, but I think it's probably about as close as it's gonna get in Torque.

 

Good work. Thank you.

 

Pikachu - it looks like you've really grabbed the Torque saddle horn and gave it a good kick. I can "reduce" the math on the formulas... but there is no way I can find the time to take it to the level you have. You should be the Torque "Pro", and I'll stick with reading data.

 

Thanks, but all I really did was find a pressure altitude chart online and plug some of the values into a point/slope calculator (also online) since I couldn't remember the formulas from algebra class. Besides, I was never very good at algebra anyhow

 

Tugly, I have someyhing for you to ponder. The Scanguage 2 will read the water temp with what they call the Xguage. It seems to be very accurate. They have their own way of entering the coding to do this. Are some people out there that can break down the code to convert it to the Torque app?

Here is a copy of the Xcodes that I use in the Scanguage now.


Coolant Temp:
TXD: C410F1221139
RXF: 046205110639
RXD Engine: 3008
MTH: 00010002007F
NAM: ect

The value displayed by this XGauge is only valid after the coolant temperature gets above 127* F. Before the engine is warmed up the displayed value will go up to 255 this about double actual then start over at 127. This is becasue this PID is scaled for two different ranges. It works good on my 2000 7.3 and seems to be accurate. This has been a long sought after XGauge for the 7.3 crowd for quite some time.

Glow Plug Percent:
TXD: C410F1221430
RXF: 046205140630
RXD: 3008
MTH: 0F5127100000
NAM: gp%

This is a good way to see how long your glow plugs are staying on. They will stay on for quite a while after the engine is running and the glow plug (wait to start) light has gone out.
Engine Oil Temp:
TXD: C410F1221310
RXF: 046205130610
RXD: 3010
MTH: 000901F4FFFD8
NAM: EOT

IPR Duty Cycle:
TXD: C410F1221434
RXF: 046205140634
RXD: 3008
MTH: 006400FF0000
NAM: IPR

Injection Control Pressure:
TXD: C410F1221446
RXF: 046205140646
RXD: 3010
MTH: 003800640000
NAM: ICP

Exhuast Back Pressure:
TXD: C410F1221445
RXF: 046205140645
RXD: 3010
MTH: 016C03E80000
NAM: EBP

Transmission Fluid Temp: (This one is already documented in their XGauge Ford PWM section)
TXD: C410F1221674
RXF: 046205160674
RXD: 3010
MTH: 000100080000
NAM: TFT

 

Coolant temp is only available via OBD if the truck has a manual transmission. The coolant temp sensor on an automatic truck doesn't send any signal at all to the PCM.

 

Yes the truck is a manual trans.

 

Yes I wrote some PHP code to do just that. I haven't really tested it fully yet, but I'll run some of those through it when I have a chance and see what it spits out.

 

Those are cool. Glow plug percent is 1221430, with what looks to be a header of C410F. I would guess the TXF is the transmit (or request) code. The RXF looks to be something like "Receive Code" The "MTH" is a complex inner-code thing... assuming that means "math". I see three hexadecimal "words", and I think I see a typo in your Engine Oil Temp.

Playing with the TFT, let's see what's similar:

Torque on Superduty
Transmission Fluid Temperature
Short Name: TFT
PID: 221674
Units: °F
Max/Min: 250.0/0.0
Equation: ((A*256)+B)/8

Torque on OBS/some E99s
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

Xcodes
TXD: C410F1221674
RXF: 046205160674
RXD: 3010
MTH: 000100080000
NAM: TFT

I find it interesting that the second 4-digit "word" in the MTH line is 8, and the Torque formula has "divided by 8" in it.

 

Tugly,

I could be wrong but should the formula be (((A*256)+B)*0.03625)-BARO()

 

Thanks for catching that. I just edited several parts of the first post with new information, so you may want to scan it for PIDs you use.

 

May I trouble someone to post all the Torque entries needed to create a custom PID to monitor Accelerator Pedal Position. I have a new phone and can't get the formula from my old phone to work.

Thank you.
