Octane Adjust Ratio monitoring?

Hi!

I'm trying to monitor Octane Adjust Ratio parameter available on 2.3 Ecoboost and other Ford motors.

The only similar parameter I've found for PCM module is OCTADJ_R_LRND measured in %. Is this the right one?

Also, other sources like Cobb say it's measured in values from -1.0 (being the best) to 1.0 (being the worst). What is the values range in Forscan? I've seen 76.43% with RON92 fuel, now I have about 90% with RON95. Gonna test RON98 and RON100, but I can't understand how do these percentage values in Forscan correspond to -1.0 - 1.0 range.

Thanks!
