Is OAR another way of displaying inferred octane? Or is more of an indication of correct fuel for a given tune? It seems like OAR of -1 is equal to 98 octane on my E30 tune comparing it to the inferred octane reading. is -1 the highest it can reach?
I know I'll probably end up buying one of the ethanol analyzers eventually.
