Yep, I've added the extra pids for DPF% and regen on my Torque Pro app, just have to go for a good run to see what happens.

Result: nothing at all...........

The BlueDriver seems to be a good set up.

Hello all been awhile since being on here but I have a sensor fault showing up
P061B
Internal control module torque calculation performance

The engine light just comes on, then when you check it using my FIXD device it shows this code but when you turn the car off then back on the fault is gone even on the scanner until next time.
Is this a big issue as I will be towing a large trailer in two weeks.
How to fix would be good don’t trust Jeep here and my local mechanic does not know a lot about Jeep
Mines a diesel 103,000k up till today replaced MAP sensor as it was faulty.
Have a catch can plus a stainless turbo muffler newly installed.
No big issues till this.

Hi Folks Two other useful OBDII scanners that i use are the following.

The first thing you need to do before using either of these Scanners is update their firmware.
you can find the update software on the manufacturers Web site in the support section

This one is good to keep in the car for when you get and error code while out and about
so you can check to see what the engine light is bitching about, you can scan then if not serious clear the code.

And this far more advanced Bluetooth Unit that has IOS 12 and Later (iPad, iPhone & iPod Touch) as well as Android and PC interface,
You will need a WIFI connection for updating the app while in use, I connect to it with My iPad Mini Gen3 to connect to it,
and use personal hot spot off my iPhone for WIFI.

there are 2 very good apps for this Bluetooth unit.

The manufacturers APP, good for monitoring and clearing error codes.

And

OBD JScan, very powerful app for making changes to ECU settings as well as monitoring and clearing error codes.
https://jscan.net/

OBD JScan is powerful Jeep diagnostic app. JScan allows reading standard DTCs (emission related), live data and more.

When using OBD JScan the first thing you should do is BackUp your current ECU profile so you can restore it later if you make any mistakes,
this is easy to do just

1) Tap the gear icon top right corner of app window
2) Tap "Trace & Restore Adaptations"
3) Tap Restore tab
4) Tap the yellow icon bottom left corner
5) Tap the "Start BackUp" icon bottom right corner.

you also have to buy a AU$37.00 licence for the JScan app,
the licence only cover ONE vehicle so you will have to buy a licence for each vehicle you use this app on,
it tracks the Licence off the VIN code in the ECU to track the vehicle specs and app licences.

JSCAN also has a DEMO mode so you can browse thought it to see just exactly what your get for you subscription FEE
BEFORE you decide to pay the subscription fee.

Download iOS Version (IOS 12 and later for IPad, iPhone & iPod touch)
Compatible with OBDLink MX+

Download Android Version
Compatible with OBDLink MX+,

DO NOT have the motor running when Clearing error code or making ECU setting changes while using the JScan app, just cycle the ignition to the run position
E.G press the button twice WITHOUT having your foot on the brake peddle, or turn the key to the run position with out starting the motor.
the motor should only be running when using the monitoring side of the apps

ALSO read the user guide before you start, for one very good reason as my signature states.

K nobody replied to your question i see,
The JSCAN app has ABS Bleed and calibrate functions,

There is a Demo Mode so you can have a look at the app without actually having the OBDII scanner in the car or paying the licence fee,
JSCAN has diagnostics and ECU adjustment feature, and cover a lot of MOPAR's
that have OBDII ports

I just bought the Foxwell NT204 for my wife's MY14 GC Overland in case we need to clear codes when away. Well, it doesn't work - it powers up but will not communicate with the GC. I had trouble updating the NT204 (software did not recognise the unit, even though plugged into the laptop via USB and clearly powered on , but deleted/reloaded the software on my laptop, tried again and updated fine (to EN/RU latest). Still no go with the GC, then tried a 2005 M-B A170, also no go. Was about to return the Foxwell but thought I'd try on a friend's 2010 CJ Lancer -- no problem, linked straight away. Tried again in the GC, even tried holding the OBDII plug, no go, just spends ages searching for the right protocol and eventually says 'No Communicating'.

I will try the Foxwell support chaps again an see what they say (could be the USB pins have spread and no no contact), but any suggestions from anyone here? Thanks!
