The pcv is availible now, atleast I was able to buy one, along with their auto-tune extra add-on, from dyno jet (the company), here is the link to where I bought mine from: Dynojet - Power Commander V - KTM RC390 15
I have no affiliation that is just the only place I found when looking.
And this is the auto-tuner that you buy extra: Fuel MotoDynojet - Auto Tune Kit For Power Commander V
