So I'm pretty sure the throttle maps are meant to imitate the more intuitive aspects of a cable throttle (on the highway for example I feel like cable throttle makes you step a lot more to get more speed, because you're "locally" directly controlling airflow and thus power, not torque. The one throttle map I've seen is for the BRZ/FRS and it basically almost all of the change in commanded torque happens in the middle third of pedal travel. Pushing the pedal to the metal doesn't add nearly as much power as pushing from fully lifted to halfwayish.
I think the e-throttle maps are one of the more easily modified things when reflashing an ECU, but not sure. Should be pretty easy to give it a gentler torque ramp up.
