How to find current tune installed on car

Just wanted to know how I can see in VersaTuner what is my current tune installed on my car is ? 
No you can't... Basically Versatuner or any tuning software will get all those calibration tables, will encode them in a format that the ECU tune will understand and then will write that thing into the ECU.
There is no calibration versioning for the data written into the ECU flash memory so even reading the whole thing and deconding it back will have to go through a comparison process with all the tunes you have in your tune database on the device you used for reading (which is not that hard I think but requires further coding and it's not something that defines the purpose of the software).
Personally I know that on the car I always have the latest tune I exported as a file. Even if I change something to a tune, I flash it, I don't like it and I want to put the previous one back, instead I create a new version and I revert the change I did not like.
I guess that's one of the reasons my I have like 200+ tunes that piled up in my tunes folder but over time I found this to be the easiest way (right after modifying the last tune and flashing it because I forgot I did not like the change and flashed an older one instead, so I ended up with the tune I didn't like plus some other nasty things I wanted to test and the resulted behavior has harder to interpret).
