I had a devil of a time in Windows just to rename the file to drop the ".txt". Unfortunately I don't recall what I did (dropped the text into Excel and save as ".CSV" maybe?), but once I got the file named correctly everything worked as described.

Sorry I can't be of better help.

Are you finding the "torque" folder?

Here's a quick step by step:

1. Download the file from this thread
2. Delete the .txt from the file name (I did this on my computer, can be done on your device)
3. Upload the file to your device using DropBox, GoogleDrive, manual transfer etc. if you used your computer to download it. Otherwise skip this step
4. Use your file manager application to find the file and cut/copy/move it (Should be in your download folder, or wherever you put it)
5. Turn on show hidden files in your file browser application (very important or you won't be able to find the .torque folder)
6. Paste the file that you moved/copied earlier into: /sdcard/.torque/extendedpids/ ( I had to create the extendidpids folder)
7. Load the torque program and go to: Settings->Manage extra PIDs/Sensors->Add predefined set and select your file "BMW 335d.csv"
8. A list of PIDs will come up, select the "BMW 335d"
9. You will see the new PIDs listed
10. Add displays to your real time dashboard!

Step 7 taken from the Torque wiki here:
http://torquebhp.wikia.com/wiki/How_..._extended_PIDs
There is a VIDEO in there as well showing step 7

Hope that helps

I think the standard android browser doesn't play well with attachments it can't find an app for. At least mine didn't. It called the file data.bin and it was unable. I used chrome without problem. I used es file explorer to rename it.

Big thanks to DWR for this, been using it for a while.

Interesting thing I noted the last couple of days; I actually see a vacuum reported of about 4.5 psi at very slight partial throttle but only when the car is cold. Diesels don't usually pull vacuum since there is typically no throttle, but the M57 does have an electronic throttle valve. My guess is that it is only actuated when cold, but for what purpose I cannot imagine.

Anyone else see this behavior?

You still have a functional EGR system? If so, that's normal. The system will close the throttle to help pull exhaust gases through the EGR path and vacuum conditions can occur in some operating conditions.

I have a block plate at the EGR valve but not one at the turbo. However, I thought I noticed that EGR Commanded was 0 during warm-up, I will have to look again.

Interestingly, I had a DPF regen this morning and saw quite a bit of vacuum, the only time I have seen negative PSI when warm.

While I appreciate the notion that closing the throttle will pull more EGR, it seems the two circumstances where I have seen a vacuum state are the times when EGR Commanded usually goes to 0; warm-up and regen.

This may be interesting to you. Some old data from stock behavior I had collected back in 2012 comparing EGR and Throttle behavior during drives to work where no DPF regen was occurring and then one with DPF regen occurring.

Also, during warm up there can be some post injection events used, and the EGR position usually closes during post injection events to keep raw fuel from being dumped back into the intake.

Thanks TDIwyse, this is very interesting. Seems to verify my intuition: both the throttle and EGR generally close during warm up and regens. All of this is well beyond my understanding of this stuff! I just thought it interesting to see the engine pull a bit of a vacuum under certain conditions.

This looks amazing thanks.

Any idea of how should amend the temp pids to show the values in celsius?

Update 335d extended PIDs for Torque

So, I made a couple of adds and mods to the extended PIDs.

DPF differential pressure: For those of you still with DPF, there is a differential pressure PID. There is still pressure loss downstream, but it is a smaller effect. I built that so I could do something even more interesting for those without DPFs.

Turbo Drive Pressure: It takes the exhaust manifold pressure and subtracts the DPF differential pressure reading, to estimate the net pressure on the turbine. So, all you alphabet soupers can just have that 2nd pressure port disconnected - open to ambient air - and you will get the differential pressure of the entire exhaust after the turbo.

Boost Pressure: TDIwyse and I were breaking some spare parts he had (inside joke, sorry) when I realised a modification could be made to improve the original version. I think this one does a better job at higher psi. Let me know if you agree.

H20/Meth Target: Based on lots of testing and research, this PID sets a target H20/Methanol injection flow, for a 50/50 mixture. It gives cc/min, the same units used to size nozzles. Using a ratio for diesel/H20/Methanol, this should get you in the ballpark (no way it can optimize every setup).

Now you still have to figure out how to control the flow to meet the target. For anyone with fuel rail pressure manipulation (JBD and the like), this may under predict maximum flow. Finally, I should note if you go up in methanol concentration, watch those exhaust temps. If you are using less than 50%, say windshield fluid, then you may need to adjust the "25" multiple to "20" or less.

Hopefully, some enterprising folks can give feedback for further fine tuning. I'd like to include AFR and exhaust temp at some point, so this becomes a very useful H20/Meth tuning tool.

As before, strip the "txt" suffix from the attached file, so Torque can recognize it. See instructions in earlier posts on where to paste it.
Here's a listing for those that have difficulty getting the attachment into Torque:

Fantastic. Thank you Santa.

Of course, now I'm going to have to re-baseline all kinds of parameters...

Just a note to others... if you setup a logging profile and included some of these PIDs, you'll want to delete and then re-enter the new PIDs for the updated equations to take affect in the logging parameters. At least that's what happened in my version of Torque.

Hmmm, I have two phones with Torque installed. The one affixed and dedicated to the car has an older version of Torque, and it was the one I needed to delete and re-enter the PIDs. My new phone with the updated Torque didn't need this step to get the updated equations into the logging parameter equations...

Thanks for the reminder TDIwyse. Yes, as standard procedure I clear the logs, gauges and old PID file. Otherwise, I have had inconsistent results.

AFR now reads correctly for a diesel, instead of gas. Small adjustment, but what the heck, let's get it right.

Boost was the worst offender. Torque's version was just plain wrong. Now you can have a reading that matches an analog gauge! Same with exhaust manifold pressure, and in psi.

Air Mass wasn't even in mass units. Now you can log lbs/min and see where the LP compressor maxes out on a compressor map. And see how it is very much temperature dependent.

Speaking of which, ambient air, intake air and charge air cooler temperatures are all there in Fahrenheit degrees.

Fuel Flow in lbs/hr so you can estimate crank HP from BSFC (~0.4lbs/HP/hr) Unless, you are adding fuel by fuel rail pressure manipulation or methanol injection. Then all bets are off.

All 3 exhaust temperature probes can be monitored in Fahrenheit.

The full configuration is in the attached "BMW 335d.csv"

Just copy the file into the .torque/extendedpids folder (remember to remove the 'txt' suffix from the file name). Then select settings in the main menu of Torque. From there scroll down to "Manage extra PIDs/Sensors" and select. From the menu icon in the upper right hand corner select "Add predefined set", then you will see BMW 335d. Select that and the csv file parameters will be loaded for you to select from, just as you would any other parameter in Torque. Note, I formatted the parameter names so that they appear at the top of list and are easy to find.
Enjoy.
You the man!
