Octane rating for chips

[MSDGN]

This is a question for everyone but preferably any chip burners...when you burn a chip for a specific Octane rating is that rating related to Antiknock(R+M)/2 or Motor Octane?

Generally a 93 Octance chip is for 93 Octane Pumpgas, which is done with the R+M/2 method. I would say the same thing goes for Racegas. A 110 chip needs to have 110 octane or better using the same method as above.
