Which ELM327 support LTFT/STFT with X350?
ELM327 V1 5 Bluetooth Interface OBD2 Auto Scanner Adapter Tool Torque Android | eBay
I have the unit in the Ebay link and using the Torque free version on Android.
One thing that I couldn't get info is LTFT/STFT info because from Torque it said no data on the sensor, I also doesn't get Voltage reading also.
Just wondering if I need to purchase different type of ELM327 unit to get those ability or if I need to use the Torque Pro version that have to pay for.
Thanks.

I have got an umber of them off ebay and they all showed the Trim data
You should have STFT and LTFT for banks 1 and 2
Not sure if Torque Free is the limitation as I have Torque Pro but make sure Torque is setup to scan for protocols on connection so it picks up as many pids as possible
All my ELM's are bluetooth. The only other difference is the latter one is shorter. The short ones don't stick out below the dashboard

As I said I have torque pro not free.
I can only assume the free version does not have all the PIDS available that Pro has
On Pro the sensors are
Fuel Trim Bank 1 Long Term
Fuel Trim Bank 2 Long Term
Fuel Trim Bank 1 Short Term
Fuel Trim Bank 2 Short Term
I can only suggest you upgrade to Pro or post a question on the torque forum

Hi: Just got torque pro to run on a tablet plus elm327 for my 04 xj8; trying to find out why it turns on CEL after several drive cycles. Code is p0171 only but my LTFT is consistently high on both banks. MAF had melted and become physically distorted out of shape; got a new one but car would not clear code on its own. Am using the app to turn off light but it returns after a while. I want to look at O2 but there are four on each side. Which ones do I need to watch? Also, I cannot get torque to show battery voltage. I added that gauge to the screen but there seems to be no data. Learning curve on this is steep at least for me. What am I missing here? Thank you.

IE a vac leak will look different to an exhaust leak and so on
Rather than try to explain it here best to read the fuel trim primer and post any questions on things you need clarified

Not sure where in the forum is best place for my questions...I jumped in here since I am using ELM327 bluetooth dongle with torque pro app. My car was fine until idiots at local oil change and brake shop sent me home with air intake open to atmosphere unbeknownst to me. A month later, CEL came on and I then discovered open air filter and corrected it. MAF was found to be all twisted and melted; one person on here suggested it had been put through repeated super-heat clean cycles by ECM due to dirt accumulation. With new MAF, car is not turning off CEL so I got torque pro and reader. LTFT on both banks runs around +16% consistently. STFT both sides runs between zero and -~8%. O2 sensors both sides run around .8V putt-putting in city traffic where RPM rarely exceeds 2200 and lives mostly around 1500. I put out CEL with command from torque but it came back once; holding my breath to see what next. Car feels completely normal. Thank you.

I tried the test: after drive through town and normal temps all around, sat out in front of my house at 2600 RPM for a couple minutes. LTFT did not go down but stayed at +12-15% both sides. STFTs now have crept up to zero on both sides and CEL came back on. I am just about ready to pull off battery cable and short them together and reboot the ECM.

If you do, drive it a few days till you check trims again as it needs to relearn.
Figures above aren't an air leak.
Maybe a dirty/bad MAF.
BTW, revving for about 10 secs is enough with an already warmed up engine. You just need the LTFTs to have enough time to be readable and fairly steady.
