TSDZ2 Versions - ECU possibility

[pedalfettal]

Does anyone know/think/agree that I could put a pre-2022 ECU into the version 2?

If so then it might be worth getting the version 2 for the low-pedal resistance and then replace with older ECU for the OSF firmware capability.


My notes on TSDZ2 versions:

TSDZ2 version 1
- to June-2022:
- 36V and 48V
- CSK30P Sprag clutch (aliexpress £20, wychbearings £20)
- ECU has red beans parallel with mosfets (aliexpress £26)
- OSF firmware possible
- Earliest versions had two cartridge bearings on crank-shaft non-drive-side
- TSDZ2B refers to trick brake version

TSDZ2 version 2
- from July-2022:
- 36V and 48V
- Proprietary Tongsheng sprag clutch
- ECU red beans perpendicular to mosfets
- Firmware locked
- Seen advertised as TSDZ2B and TSDZ2H

If the low pedal resistance is from the changed sprag clutch, does just that V2 component fit V1, and is it available as a spare part?

Has the torque sensor changed? If so controller may have changed to match.

Interested to know the answers.

Prompted by:

- E-S: "New" TSDZ2 with "old" controller?

Question changes to:

Does anyone know/think/agree that I could put a pre-2020 ECU into the new version 2?

- If so then it might be worth getting the version 2 for the low-pedal resistance and then replace with older 2020 ECU for the OSF firmware capability.


Also does anyone know/think/agree that I could put a pre-2020 ECU into the 2020 version 1?

- If so then it might be a means to use the OSF firmware on this version
