Yes, this was using the new ramp code but the trip has nothing to do with the ramping itself. The blends were just switched from Start (no T240) to TCrappy (with T240) while the Trilliums were still saturated, causing the ISI to trip on the actuators as soon as the T240s got into the blend.
 

Switching the blends after waiting for the Trilliums to quiet down, as recomended, worked perfectly fine.
