I don't think so. The table is not scalable so I would imagine its the same as other tables in which that is the hard coded limit. From what I understand if a value is surpassed, the last value is the one that is used. I'm not sure why your numbers are high. I'm still well within the limits. How much boost are you running? I am running 9psi and only manage to hit about 1.12 with about 16 adv at 7200rpm. My high octane is only about 9 adv in that area though. I use other tables to add to the spark based on PE and IAT, but they are limited too.
