Engaging throttle while using PAS. Is input voltage added?

[Slaphappygamer]

I’m in PAS 2 and feather the throttle when coming to a steep incline. I’m using a 25A KT controller and C5 is set to 10. My speed is limited to 25mph.

When I’m using PAS (any level really), I don’t need to engage the throttle much and I’ll get boosted. I’ll keep the throttle at the same position and stop pedaling. I find that my wattage drops, significantly. I can feel it. I know that PAS has a working voltage, and so does the throttle. My question is, when PAS is engaged, does the throttle voltage get “added” as “total input voltage”? Are the PAS and throttle voltage added when both are engaged?

Not that this is a problem, or issue, for me. I’m just trying to understand the relationship between the PAS and throttle better.

The way it works on My KTs at least, and I have had several over several years, is the PAS output level governs until the throttle demand becomes larger, and then throttle takes over. I use the 25a controllers myself, but on the 35a units, if you set C14=3 you can get more output - and faster acceleration from zero - with pedal assist.

I have heard people say that throttle on a KT controller is on or off, all or nothing, and that has not been my experience at all.

I've used KT controllers a lot too. To me, it just feels like the throttle becomes active when it asks for more power than what the pedal assist is providing. Feathers in quite well, and none of them were ever on-off.

It does seem that the throttle only riding shows less power on the display than pedal assist. Other people have noticed this too. I don't have cruise control enabled, but you could try riding the same stretch under cruise and with pedal assist to compare what the readings are. Then again, when I ride in PAS 1 at a constant speed, the power might fluctuate between 80 and 120. You should try ghost pedalling to see if the power output is lower and if it stays constant, There's the variable of the rider power involved when looking at PAS. Might as well remove it
