So one of the things that was really useful in the RC-CA thread was discussions about throttle mapping. In the original RC-CA, there device was setup only as a current throttle, and the input throttle range was limited over a 3V span via the AuxInput function. In the setup menu for the V3 CA's input throttle, you can specify both minimum and maximum input range allowing you to dial in just where the start and end zones are for the throttle motion, regardless of whether you have a potentiometer or a hall effect throttle type.
The output throttle range is similarly settable. One thing we've noticed is that many newer controllers run the hall throttles off a 4.3V supply rather than a 5V supply, and so instead of the usual 0.9-4.2V input range, they see a 0.9-3.6V range, with full throttle being at about 3.4V and with a 4V signal being considered a fault condition. So this way the CA's output can be adjusted to match properly with what the controller expects:

And of course, you can select whether the output throttle is a voltage signal as per ebike controllers, or a servo pulse signal as used by RC controllers
In the RC output mode, there is no need to change any hardware on the CA, the same green wire in the 6-pin CA-DP connector will supply either a steady voltage or the pulse stream, and the min and max output ranges are then displayed in units of mS:
Back to the input throttle, there is a selection menu to now choose what the throttle controls, so you have the option of ignoring the input throttle, or treating it as a current throttle, a speed throttle, or now a Pass-Thru throttle. In pass-thru mode, the CA basically takes the input throttle within the input throttle range, and maps it over to the output throttle range. So this way if you don't want the CA's feedback loops to come into the picture, you can have it pass your own command throttle straight to the controller. But with the remapping capability of the input/output ranges, it means you can use potentiometer throttle on a controller expecting a hall input, a hall throttle on a potentiometer controller, or any throttle with an RC controller etc.

And finally to give more of a soft start feeling to the ebike, and especially to reduce gear and clutch failures in geared drives, there is a throttle output rate limit that regardless of all other settings puts a firm clamp on how rapidly the throttle output of the CA can change:

Some people like the instant kick of an instant throttle, while others find it disconcerting and prefer the power to ease in smoothly, and so with the rate limit this can be set to the user's preference.
