This is a mistake.
You are using a steering curve to calm down a fast servo - the steering might feel less sensitive near the centre, but it is still just as twitchy (relatively more so) close to full lock.
If the servo is too fast... move your finger/thumb more slowly! Or fit a basic Futaba which is pretty much all the servo most of us need in a touring car.
I only ever use sub-trim, EPA (end-point), EXP (exponential) and the dual rate, and only on the steering.
Everything else is set to 100% and linear. If the throttle feel is wrong, I use the ESC's own programming.
For the steering, set the sub-trim for symmetrical geometry on the steering linkages. Then, with dual rate at 100%, use the EPA to get full lock (no more, no less) when steering each way. On the track, decrease the dual-rate if necessary to decrease total steering. I always make sure the car can still turn full circle in the width of the narrowest normal section of track, so I'm rarely below 85-90% personally. Use the EXP to adjust the feel of the car with small inputs, I use corrections on the straight as a guide, never more than 10%.
As stated above, big adjustments and gimmicky adjustments just mask the true handling of the car - they won't make you any faster. Make the car handle well, use your hands to drive it fast, not the transmitter menus!
