Diesel Particulate Filter - DPF

[sublime]

seems the administrators don't want this fix displayed

What fix? You have not displayed or detailed any fix... Just spruiked for a business.

I'm with you Toonga! Has there been a thread started to notify the moderators?

+1.. if not going to be helpful then just pay the Admin a fee and then advertise your business.. how hard is that?

[El_Freddo]

He knows NOTHING of the FIX!

I now monitor my DPF regens through an OBD-II Bluetooth interface and Torque Pro on Android. At least it warns me during the DPF regen.

Thanks to Ghostgum (and Subdiesel/ Subaru diesel crew site) for the PIDs to get me going, I was stuck figuring it out!

Note the temps in this image are somewhat extreme and don't normally go that high (more around the 600-650C level).

[ghostgum]

What PID values did you use for those temperatures?

Hi Ghostgum,

See here for the details of the following:

• Estimated DPF Temperature Mode And PID: 22114C
• Estimated Catalyst Temperature Mode And PID: 22114B
• Exhaust Gas Temp at DPF Mode And PID: 22003E

Awesome and must get TP.. thanks

Can you data log this info?

[pitrack_1]

No probs

Can you data log this info?

Yes. Text CSV (comma delimited) file, easily importable to just about anything. You can select the parameters to log. Many options. GPS too if you wish to track your drive.

Here's a sample with the DPF turning on (value 0 -> 255). Copy the lines below (note word wrapping may interfere with the full line) into a text file, save with .csv extension, import into excel (should give lots of columns) and plot Time vs DPF Active Regeneration Switch as a scatter line graph.

Waa, what next ?! Wait 'til the marketers get onto this, no worries about vehicles reliability, performance or longevity. Right now the ads only seem to spruik no need to buy after market stuff coz it all comes with sat nav, bluetooth, auto park assist and now Torque Pro !

[RSR 555]

Excellent. It would be good to know what terrain the car is on while this is happening, so GPS would work great.

Sounds good. I just had word from my Subaru Rep that our 2010 Foz has had the "upgrade" to the ECU to help with the DPF fault. Once I have our Data Log I'll let you know what mine looks like.

Doubt you see this from the marketers.. Manufactures don't want people seeing this info but it's been available to them since EFI

[pitrack_1]

There's a few holes, but overall Torque Pro is a very nice piece of work. It even has a 'HUD' mode- reverses the readout (R to L) for display by reflection off the windscreen.

My interface is on the blink (or I've damaged the plug/socket ), see error below, so buying a new (better) one- should hopefully have SSM access/capability too. Will let you know how it goes.

Some info for you, RSR555:

1. There have been a few instances (lots for me recently) of code U0073 (Network Error) being thrown. This can be cleared with Torque Pro, has been suspected it may even be caused by Torque Pro on occasion. Mine may be my interface failing. I have logged many Mb and hours without any issue previously. The symptom is the Christmas tree lights up, complete with flasher. You'll know what I mean when it happens
2. U0073 whist driving produces unpredictable results. Sometimes the performance is impeded, the steering may drop to a default (min) assistance level, lots of electronic bits don't work (including after recycling ignition) incl cruise, have had a rpm limit ~3000 once, seems to lose knock sensing/balancing at idle, etc.
3. For when you're finding stuff in Torque Pro, storage directories are all over the place. Some I've found are (on a Nexus 7 2013):
   • /storage/emulated/0/.torque (various- config save files and logs)
   • /storage/emulated/0/.torque/tripLogs (for the GPS logs I think- GPS not activated by me)
   • /storage/emulated/0/torqueLogs (data logs, can include GPS readouts if specified I think)
   • /storage/emulated/0/torqueTrackLog.csv (seems to be a GPS dedicated log file)
4. A Nexus 7 2013 seems it could fit nicely where the stereo (if it can be called that) unit is in a 2010

Excellent pitrack_1

I just got given a Nexus 7 tablet for helping a friend put his supercharger in his Nissan 350Z, so I will put this tablet straight to good use

Cheers,

Hi Paul,

Well then here's a couple of files to get you started. Unzip the attached .zip, the two files inside for Torque Pro DPF monitoring are the dash setup and custom PIDs. Drop them in the appropriate directories under /storage/emulated/0/.torque/dashboards and /storage/emulated/0/.torque/extendedpids .

To do this, you'll need a file manager type program (free downloads) such as Ghost Commander (can send your logs to PC via Bluetooth) and File Commander (can act as a very basic music player- queue audio files, see below).

And the Nexus 7 (2013 or version 2) plugs nicely into the AUX-IN port (centre console bottom rear, underneath centre armrest on the 2010) to act as a music box too. You just need a standard stereo headphone socket (2.5mm?) male-male link cable.

Just achieved tonight...

[steptoe]

Hope that milestone was achieved in the driveway or somewhere safe to take the pic

Supercharger on a 350Z ??!! Been lucky enough to have driven a few can't imagine why anyone needs a SC on one of these rockets ? Trying to shred the fibreglass or is it kevlar - tailshaft ??

Hey Patrick,

Thanks heaps for this and I'll have a play and let you know how it goes. We haven't got her new Foz yet we pickup in a couple of weeks. We got it for under 20k and it has just hit 100k like yours. I can't wait to try out this Nexus and Torque Pro setup

Very.. not bad for a 21yo Uni student

[pitrack_1]

I think I found the OBD2 DPF Regeneration Count parameter.

At a service two weeks ago the DPF regen count was 51. That's one regeneration per week for the life of the car.

...

So the settings I am using in Torque Pro for regen count are:
OBD2 Mode and PID is 221157, Long name "DPF Active Regeneration Count", Short name "Regen", min 0, max 65535, scale x1, Unit type [blank], Equation A*256+B. The equation may be incorrect - I won't know until it reaches 255 which will be another 4 years.

I can confirm it hits the "hexadecimal century" at 256 and rolls over from 00FF (255) to 0100 (256).

Sorry but I forgot to take an image of the 00FF reading (255) but below is an excerpt from my logging confirming the rollover.

Code: Select all

Device Time	DPF Active Regen Switch(on/off)	DPF Active Regen Count
40:48.7		255				255
40:49.2		255				255
40:49.8		0				256
40:50.3		0				256

Hi Paul,

here's where I've set up my Nexus 7 2013. It's held in place by velcro on the Nexus' aftermarket case and on the dash. It fits uncannily well over the head unit...I don't miss much 'cos I listen to the radio and the buttons are on the wheel.

The Nexus' auto-dim adapts very well indeed, just slightly dim in full sun. Positioning over the head unit gives a reasonable ergonomic location for control of Torque or music. It's close to the dash console power outlet (for power) but away from the centre cubby aux-in port (for music).
