Also regarding the OTS E85 tune, is there room for more timing advance for true E85? @ shiv@vishnu says anything greater than E60 is fine, just wondering if he built in a large safety margin or if its that you just can't benefit from any further timing advance.

Our OTS maps have been calibrated for 91-93oct. We leave a little bit on the table for 93oct folks. 91oct folks (such as myself) also operate conservatively but may see some KR from time to time in very warm conditions. But Adv Multiplier should stay at 1 (or close to it) most of the time.
With E85, you will achieve all the knock resistance you can need with just E60. At that E% you have enough octane to run max timing for best torque. No sense in running more advance because you will actually start to lose power (even without the presence of knock). So going to E85 is, in many ways, overkill. It's just more convenient since you can just fill 'er up instead of mixing fuel carefully.
