We are aware of an issue in the 3815 that is not allowing users to select custom options (shift points and rev) in the 87 octane program. This has happened to some FP users after the update for the datalogging. Update your tuner to D/B53 and this should solve this issues.
If this does not correct this issue then email me directly and I will look into it.
