John,
Surprisingly the Rotax Owner website does not show the Rev 2 of this SL.
To get R2, search the Rotax factory website https://www.flyrotax.com/home.html

need to read this SL in detail but the chart presented is a total departure
from all the information presented in the past. If I interpret it correctly,
with RON 95, you have to be at 5500 RPM to be 100% sure you will not have a detonation
event at WOT. On the other hand, anything over 4000 RPM with RON 98 @
WOT is safe.

I was using 50-50 ethanol free 90 and premium 93 but in light of this chart
I think the gain is safety, while I experiment with my prop, is huge if using
the higher grade gasoline.

I do have a DUC Swirl that makes similar claims and once I finish testing my Woodcomp
(which is not looking very impressive so far) I will try the DUC. But
would like to learn more about this EProps V20.
