the engine occasionally misses a spark/ticks a itty bit if I use 91 AKI (95 RON gas) with 10% Ethanol. But there is no problem when I use 94 AKI (98 RON octane)

Weird. The posted minimum octane rating for fuel injected Vaz/Ladas is 91AKI/95RON.

And the compression rate is 9.8:1

I have CAI too, so it can't be that either.
