Is the open-source firmware still the undisputed king for the Tongsheng TSDZ8, or has the factory firmware finally caught up? In this video, I put the 2025 Tongsheng factory firmware to the test after switching back from the popular open-source version (mstrens/OSF).
The results are shocking. The factory firmware that came loaded on my Powallon TSDZ8 feels significantly more powerful, torquey, and responsive across all speeds. We'll look at the data, showing how the factory setup pulls over 25 amps and 1300 watts, and discuss why the motor sounds faster and performs better with Tongsheng's own tuning, likely due to superior motor control.
While the open-source firmware for the TSDZ8 deserves immense credit for pioneering advanced customization and a more refined pedal-assist feel, the landscape is evolving. As Tongsheng continues to invest in its product development, the notion that its 2025 factory firmware could surpass the open-source alternatives is not just a possibility, but a logical expectation based on their inherent strengths as the original equipment manufacturer.
Join me for a detailed ride as I compare the performance, and explain why, in my opinion, the factory firmware is now the definitive way to run the TSDZ8.
This video is also a full trail test on some challenging singletrack. Join me as I navigate everything from chunky rock climbs to a newly fallen tree on the path. I'll also touch on other bike components, including my thoughts on the comfort of Ergon GP3 grips, a very creaky rear shock , and a public service announcement about an incredible sale on SRAM Guide T hydraulic brakes happening in September 2025. We'll even discuss how the TSDZ8 stacks up against competitors like the Bafang BBS02 and the CYC Photon, giving you the full picture of where this motor stands in the current e-bike market.
