Technical I can not see ltft and stft values help
you're not really helping yourself here, chap.... Perhaps you can give us some more information instead of just repeating yourself haha.
Why is it you want to look at your fuel trim values? What problem is it the car is has exactly? I'd like to understand what you hope to learn from looking at these adaptive parameters as maybe there is a better or easier way to help you.
What have you tried up until now? It sounds like you've been trying to use the Android app, Torque. What connector / cable have you got?
As Davren suggested most of us use a program called MultiECUScan, which is developed specifically for Fiat. Are you using the free version of this software or do you have the full licence for it? What diagnostic cable are you using with MultiECUScan?
So, tell us what the problem is, what you're trying to fix and what it is you've tried already and lets see if we can help.
Cheers!

That device is just the interface.
I don't know anyone on this forum that uses "torque programme", so we probably can not advise you if this interface is suitable or not.
It is not advisable to use Bluetooth interfaces if ever you want to make adjustments to the car's ECU or to carry out the Proxy Alignment procedure. Connection drop out during the adjustment or the PA procedure could destroy the ECU.

We do understand you.
That interface you have will not work with fiats, alfas etc...
You need a modified elm for multiecuscan.
Torque does work with modifed elm... but you have standard elm (ford etc)... fiat elm had a resistor of some sort... just buy an elm modified for multiecuscan.
If multiecuscan works... torque should work too (might be less informative than multiecuscan).
So... get the correct cable and show us that MES can talk to the car... then we might be able to help.
Also... dont go bluetooth for anything other than reading codes... big no no.

Hi, That interface should work, but some of the cheap ones like that have a fault that stops them working on some cars / ECUs. If you can connect to the engine ECU and read any parameters with Multiecuscan then the interface is working
Torque will NOT give you the fuel trim data.
Multiecuscan WILL if you have a 5SF CF4 ECU (rather than the 5NF) It is not called a long or short term fuel trim on this ECU but is called "mixture correction learning value (appears to be long term only) The 4NF ECU does not appear to have a fuel trim parameter. Are you sure the ECU you have has STFT and LTFT parameters or are you just assuming it does?

Have you read the post's?
We need to know what ECU is in your car because most of them do not have the information you are asking for
Why do you want this information anyway instead of just asking the same question
try this
Why do you want this values?
What purpose do you think they will serve?
As judging from these who know a bit about this the car does not provide the values it the form you are after

That is data from a Chevy Cruze which uses a GM / AC-Delco ECU. Different ECUs have different configurations and can have different names for the same or similar parameters. The Magneti Marelli ECU in the Stilo is different to the AC delco.
Not sure we can help much more without knowing exactly what you are trying to do. You mentioned LPG, is it a commercial conversion and is it designed for the Stilo? If not you may have to do a fair bit of work.

Its not nuclear science! He wants to know the stft and ltft values to adjust the LPG mixture by adjusting the lpg injector opening ms.
Stilo 1.2 16v shows STFT & LTFT with ELM327 @torque Pro
This is from an OBD connection from Stilo ECU to the LPG ECU
It's all greek to me
More seriously, the screen shot clearly is not Torque, it's a windows program. You are also syaing it' conneted to an LPG ECU, that's not what the OP appeared to be asking.
Torque is also well known for showing innacurate parameter values on Fiat cars. As far as I can tell the MM 5NF ECU does not use STFT LTFT parameters.
Guessing what the OP wants does not really help, we can all guess.
