Is Euro 95 RON gas causing misfire?

So, it's very hard to find "Speciale (98 RON)" where I live in Italy. Like, I haven't seen it yet. Regardless, I have a fuel card program that limits where I can buy fuel. The "Normale" unleaded here is 95 RON; however, from what I've read, this is equivalent to around US 89 RON. Here's my reference:

"In Europe, the octane rating on the pump is simply the RON figure. America, by contrast, uses the average of the RON and the MON figures, called the AKI (anti-knock index). Thus, 97 octane "super unleaded" in Britain is roughly equivalent to 91 octane premium in the United States."

I'm getting a quick misfire under full throttle in the lower gears (1st and 2nd). Feels like the limiter kicks in for 1 second but, engine doesn't free rev and no traction/warning light. Don't think its the protection circuit. With my tuner and open intake/ exhaust setup, do you think it's a compression ratio issue? Engine runs perfect otherwise and no stumble in higher gears, though I may be noticing it runs slightly better when I use a fuel additive (Seafoam).

Just put the bike back together after a long hibernation and haven't touched the RB Evo maps since it went cold 8 months ago. I've experienced a lack of fuel pressure and it's not that. I will say that she was fed US Super for her first 4 years on this planet, about 1.5 years of that with tuner. I believe I'm running a custom map and not the Autotune, so will try that next.

Just interested any of the combustion nerds opinions.

Thanks, Ferdi. Ya, the gas is never the issue. I know better but there's a lot of shady **** in this neck of the woods...google "nuclear waste found in Naples' farmer's field"

Before I tore it apart it was running really ruff. I didn't touch anything ECU related but it runs very strong now, aside from the stumble.

It's amount of throttle related, not RPM. If I gun it at any speed in 1st or 2nd, it hiccups right about when I'm at full twist. Maybe more often in 2nd than 1st.

Maybe I'm smoking crack and it's excatly at the same point you say. Haven't had a lot of time to pinpoint. I'll get a better chance this weekend. Haven't been out of touring yet because of the new tires and rain.

I'm still running the map you gave Araitim.

Kuk, you're good. It may only do misfire in 2nd, and may not do it with DTC 1 or less. I had some quick runs last night resetting my gear indicator and couldn't duplicate in my Sport mode, which is DTC 1.

And the light does give one solid blink when it happens, not a flashing like when traction control or rev limiter hits.

Nope. Got it to happen with DTC off.

However, it seems to only happen when WOT from 1st into 2nd.

I only got about 50 miles on it after initially putting the 14T on and was very easy on it. Then it went hard down for a while.
I'm gonna mess with the Evo software. Probably put it back in autotune. Funny thing is I'm not having that bogging issue I had before I loaded your map. Can't understand why that just went away.

Autotune didn't help. Your map actually runs much better.

This sucks. The buck when I hammer it is consistent and annoying. I'm going to write Dimsport. I don't think it's related to the tuner but they are headquartered in Italy and specialize in tuning Ducs. Their customer service is fanstastic, too. They respond very quickly, albeit in sometimes broken English.
