If you are using Ninco digital, then yes you will see a huge difference using O2.
Compare 32 throttle steps to 200+
I have not driven analog but I have had Ninco, then SSD, and now O2.
There is not fuel management with Oxigen, while the Slot.it software does allow for race management functions and it even recognized a pit lane. If you wanted fuel (like SCX for instance for lack of better example) you will need to buy PCLAPCOUNTER which is a 3d party application which communicates with Oxigen. I have tried their demo version and its great.
Slot.it will not come up with fuel management on their software as communicated by Maurizio.
- My personal note:
I think that Ninco track and Oxigen are a great combination. This is what I have and I could now be happier. Best grip and implementation of digital !!
I hope this helps you.
