TorqueScan for Torque Pro app

arengant · **Posted:** Sun May 19, 2013 5:33 pm

Anyone on here with the Torque Pro App try using the TorqueScan plugin to see what extended PIDs are supported? I know we (the CRD ECU) supports extra PIDs, but when I ran my scan I got ZERO results. Not sure if I need a better adapter or what. Thanks!

I've tried on a few occasions and it never completes. I believe our hacked ECU can't handle the traffic and stops communicating

I use the extension PID and have no issues, everything seems to display just fine but I don't use it constantly.
My obdii bluetooth module is a cheap one bought off ebay.

What extension PID are you talking about? I have been diving headfirst into this info and I am barely understanding it all.

I will try my Adapter and another vehicle to see if it works. My short scan completes but nothing is found, at all.

If I had to replace my phone do I need to repurchase the app?

No. If you go to the google store, it should know you have already purchased it and allow you to download it on your new phone for no additional cost. If that does not work, though, that's where it can get tricky. Has nothing to do with Torque, though.

I am still not getting it to work, but my adapter doesn't seem to work on my Grand Caravan. So either it's a Chrysler thing or an adapter problem. Once I figure out TorqueScan I am able to tackle extended PIDs...

Same here. I can't get it to work for long periods. I saw this post this morning and changed the sensors being polled by Torque this morning, but it didn't seem to make a difference.

I'll have to poke around and see if I have it set to 'log data' or something like that. Could explain it!

Are you talking about Torque as an App, or the Torque Scan plugin for the App?

Am looking at the same thing with android; Torque Pro and Torque Scan. I haven't found time to dabble yet.
What I have uncovered is this (which may answer some of Docs questions too about adding PIDs - like transmission temp etc.)
As an example for discussion purposes:
Comparing ELM327 & STN1110.
ELM327 has limited speed and free RAM is relatively small. ELM clock cycle stalls are common such that code quality is sacrificed
whereas STN1110 has plenty of memory to buffer OBD responses and eliminate Buffer Full errors even at low UART Baud rates.
ELM327 doesn't have a bootloader that allows field reflashing / programming ie a new feature cannot be added.
ELM327 only has 9600 bps to 500 kBps (low rates apparently cause stalls through being recognised as inactivity) compared to STN1110 where baud rates as low as 38 bps to as high as 10 MBps will not cause issues.
ELM327 is known not to work well or sometimes at all on some vehicles in regard to automotive algorithm detection for some vehicles running ISO 9141-2 or SAE J 1850. - STN 1110 is more easily optioned to these.
Of course there's more but this is it in a nutshell.
Among the seeming trillion other jobs that take up my time I would be keen to find the time to marry STN1110 to the Arduino platform and the my 06 KJ trying to read these things directly - just for the journey it would take my mind on.

In the meantime I am taking the shortcut method - PLX Kiwi 2 and daisy chaining the extra gauges I cannot read through the standard ELM chip system and the Phone they supply although I think it is far more flexible offering the ability to write PID's and PID interpreters. I've already fitted some stepper motor gauges - EGT; Boost; Aftercooler IN & Out.

SUMMARY: IMHO we were short changed with gauges / sensors so we need to add.

I do not see how STN1110 could be an option for us to use. Please explain. Or, is your point that STN1110 is what the developer SHOULD have used instead of ELM327?

Interesting, I haven't looked into STN1110 at all, here is a scantool article

http://www.scantool.net/scantool/downloads/102/stn1110_vs_elm327.pdf

And a Torque Pro compatible adapter using STN1170 (even better) for $85

http://batman.homelinux.com/blog/stn1170-bluetooth-obdii-adapter/stn1170-bluetooth-obdii-reader-preorder/

The above one is very similar to the scantool.net mx version (the "top of the line" that I want) so I am hoping either of these two options will help Auberon!

My virus/IS software does not like that "Batman" URL. Are you going to order one of those STN.....s and see if it works better for you than the ELM 327?

(Still have not gotten access to our Jeep when I have had time to run the scan utility and see if I get anything.)

Thanks,

The site was a from a hobbyist who makes the adapter. It is $85 currently, smaller than the ScanTool MX, but not quite the same performance.

I am pretty sure I will go with the ScanTool ($150) because it comes with A LOT more support. I didn't know that ScanTool uses the STN chip over the ELM chip. And according to the PDF I linked, the STN will work even better with our protocol! I am going to try and return my ELM (through Amazon) and get the ScanTool within the next 30 days.

Thanks arengant. This is among the offerings I've been reading.
Thanks for getting the point regarding the likelihood of a better marriage to the KJ CRD.
The reason I like the plx Kiwi system 2 is it is also very capable (when it is released) - I have also pre-ordered mine - it allows the addition by daisy chaining of (I'm sure you are aware of this) up to 16 additional sensors, the gauges for which can be read on the android device. This reader provided will run the heavyweights of android automotive diagnostics apps including ScanXL Professional which will locate up to 229 sensors (if they exist of course) but it is a comprehensive in-vehicle search and OBDII unit.
It too has a sleep mode.....a feature I am fond of.
I like the capacity for expansion......I'll have the capacity to add tranny temp, engine oil temp and the like through the daisy chain system to monitor the systems which would otherwise not be able to be monitored by OBDII as we don't physically have the sensors on the vehicle.

For Doc - the ELM chip cannot be edited/re-flashed/extended etc. It needs to be a re-issue of new software. It cannot be upgraded. Programming is confined to OBD II relevant parameters only.....then it runs out of room....it can only just carry out the simple calculations in the programing algorithms with available RAM now. Hence, it hangs up so much. I trust that explains it.

I would suggest anyone doubting the likely application of this more versatile and probably better suited chip have a read of the sites arengant has noted or just go to ScanTool.net to have a look - you will find it IS the STN chip of which I wrote.

I did not start looking at sites like this. I have only been looking at chip "workings". That is where I dwell, at times.

For sure the STN chip appears to be more capable, flexible, allows more tweaking of the data bus parameters and is much cheaper but you need the right software to enable and control this extra functionality.

There are clearly some quirks in the Jeep architecture that are going to require some "non standard" workarounds that the STN chip may or may not provide support for but someone is going to have to invest the time in understanding Chrysler's implementation and writing the appropriate software which is very specific to this single vehicle model. More than likely there will also be differences between the 05 & 06 MY.

This information can probably be purchased but is going to be expensive and only within the reach of the premium tool manufacturers. A cheap entry level/hobby solution is very unlikely.

Yep! I will buy a device with the STN1110, and see if it works while the Jeep is running around. AE supposedly can access all of the ECUs quirks, but not in a user friendly way for everyday driving. Torque App works with it so I'll keep my fingers crossed! Right now, Torque freezes about 50% of the time within 15 minutes, sometimes it never freezes. I just hope a different adapter helps.

Not able to purchase cheaply as they are just too expensive to buy your way through the protection.
As has been stated, there are ways. I have some ideas now I have a few inklings from arengant which if they prove fruitful I'll discuss with him.
One thing for sure you need to versed in C or pseudo C -that's easy as I've been doing this since punch card days in Fartran oops Fortran. We nee to develp not I=only a PID or SID (service Identifier) but an interpreter.
If the chip used has the spare room that's possible to attain but it will need someone to reboot the programming written to the chips ROM using a bootlog for want of a better term - I'm trying to help everyone understand. Its like when you restart your computer each time it runs through the bootlog to know how to set itself up.....this only has to be done once for the chip to write to ROM - easy enough. Even the Jeep runs through Countdown every time you switch on the ignition.
