2015 A/c Scrambler Map Choice?

Hi Guys, apologies if been asked before.
2015 A/C scrambler, ASI has been removed by previous owner, I've just bought a 2-1 Arrow pipe for the bike and I will be removing the O2 sensors, trouble is what map to use?.
I have used TuneECU a year or so ago on my old Speed triple, found it to be good, logged back on to the site just now and it appears to be not being updated anymore, I've looked for a map for my bike and although they are there they don't mention the removal of the O2 sensors.
My second route is the TTP site but it is quite expensive to buy a tune, I don't mind if it's the right route to do but is it the only option these days?. I have the cable so I don't need to buy the kit so to speak of TTP, I'd prefer to use Tune ECU to be honest but is it still viable.

Thanks
Mark
