Since Europe uses different standards than the US I was wondering what you all were requesting Franz to map to? I told him my area uses 93 octane (RON + MON /2) for premium fuel. I'm worried that 93 octane is too optimisitic and I should get him to rework my file to 91 octane to be safe.

I see some if not all of you have received two files - one for 91, one for 93. Which one are most of you all using?

 

I'm mapped for 93 octane only. I may request a different map for winter gas though.

 

Wonder how much whp you lose with 91 mapping vs 93?

 

since this is talking about 93 octane, i guess good ol california is excluded from this one
