Just leave it on. They only take right side panel off and PCV won't effect flash. However a new map may need to be made if it's found that flash made changes in fuel or igmition.

They should just replace the ECU with a proper built one!

Will it be safe to use the autotune until we know if they made any fueling or timing changes?
Depends on your mods. If turbo I would be careful for sure.

just intake and exhaust/header
You should be fine. May lose or gain power. Watch the rpms it will tell you.

I'm doing my wife's sled as soon as they get the software, I'm going to wait for mine since it has the evo flash I don't want to loose power, and I doubt the new flash will have more power because if it did everyone without a clutch kit would have a problem.

The Novi Yamaha rep I talked to said to call my dealer in a few weeks. Give him the vin number.
He said the new cal is an open loop system. By passes the O2. And he said it will fix the engine kick back that was breaking the starters.
Did the rep say why after flash some sleds ran better or same and some barely made it to trailer?

No. He just said the new cal will be available in a few weeks.. He just explained that the new cal will fix the kick back that was breaking the starters and have way better idle quality. And that the new cal eliminates the O2 function all together.

FWIW, my conversation with the Rep guy included a question asking if there could be some "production variance" on my sled that could cause its tune to be bad enough to start hard & foul plugs. He was almost adamant he didn't think so and pushed this new reflash most likely fixing all my issues.
On one side of the coin; I'm glad there is a reflash and hoping this is finally my sleds' fix.
On the other side of it though; The fact that some of these units are going on 3yrs old and the manufacturer is just now fessing up and putting out-of-pocket to resolve this major issue leaves a bad taste in my mouth. If I would have known I was buying a project instead of a product, I would have bought elsewhere. IMO, Yamaha has defined the purpose of their arrangement with AC and unfortunately it it is not what us Yamaha loyalists are used to.

Think we will get notified by mail again like last time?

I received notice, via e-mail from my dealer, yesterday for my 2014 XF7000. Current flash is working fine, but I'll get the update to keep the records current.
