Hi all,
i need to set up a CUSTOM mode which is halfway between ECO and SPORT modes.
So I need to know which values these default modes feature.
I suppose SPORT is just all-out with some idle regen.
However I'm curious about ECO mode: is just at 0% torque?

I've seen a similar thread about this which redirects to unofficial service manual on a wiki, however I don't think these values fit to my bike as it's written that ECO mode should have a limited top speed, which in my case is not (it reaches 140kph)

I don't know if anyone has posted on here the confirmed values but I would guess the unofficial manual is fairly accurate. Pretty sure my 2019 DS has a limited top speed in Eco mode.

I can verify that my 2018 Zero S tops out at exactly 70mph (about 112kph). In ECO mode, it has only slightly more closed-throttle and braking regen than it does in SPORT mode, but SPORT runs the top speed into the 90mph range. Moving the Custom mode to 100% in all performance parameters provides the most of everything on my bike. Top speed goes up to an indicated 98mph.

so basically CUSTOM set at 100% torque and top speed is more powerful than SPORT?

That is the way it seems on my bike.

ok I tested out ECO at max speed and it reaches 114kmh so about 70mph.

next step: have to put OBD2 interface and measure max DC current power and compare SPORT with CUSTOM set with all out.
anyway at first sight it seems CUSTOM has a smoother acceleration while SPORT is more aggressive at lower speeds.

Having recently acquired an IXXAT programming cable & DVT license for use on a 2021 SR, these are the exact settings in the Sevcon controller:
  Sport - 2.6% and 3.4% of motor torque in neutral and brake regen, respectively. Allowable motor torque is 100%. Max speed is 6484 motor RPM (about 106 mph)
  Eco - 5% and 8.5% motor torque in neutral and brake regen, respectively. Allowable motor torque is 52% of max. Max speed is 4284 motor RPM (about 70 mph).
  Custom - setting 0 regen does just that. Setting max regen in the app gives 5% and 8.5% just like ECO mode. I'm going off memory because I don't care to plug back in, but I think setting the max torque to 0 in the app sets the actual motor torque to about 36% of max. I could be wrong on that one because it isn't a parameter at which I was ever particularly looking. Unless someone really needed to know, I don't plan to jack back in to find out.

In terms of raw power output, sport and custom set to 100% are the same.

thank you so much!
as per my feelings, custom to 100% isn't better than SPORT so it matches your provided information.
then i can set CUSTOM to be more conservative than ECO, that's what I wanted to obtain: 3 different power steps
