The official answer has arrived:

I ask a Peartune dealer about these new fw compatibility questions. They answered this: Hi Zoltan! Thanks for reaching out! The Peartune is fully compatible with the latest Levo firmware update :) Just make sure to disconnect the Peartune from your bike before proceeding with the update...

The E-Bike Tuning Shop wrote: Also compatible with the latest Spezialized 3.1 Software from February 2026 (Motor 1.D.4 / Display 19.3.7 / Battery 6.10.25). Older software versions are also compatible. Here...

I've already written to PearTune, but they haven't responded yet. If they do, I'll post their response.

Has anyone tried the PearTune MSO 4.0 for Specialized 3.1 Gen4 tuning with the new firmware update that increases power to 810W/850W? If so, what is your experience? Do I need to disconnect Peartune tuning when updating the firmware?

Although I don't know what this big secret is for, Bosch announced the 100 Nm update months before, every lbs advertised the 85 Nm gen5 as 100 Nm in the summer. Even though the SW and the normal Specialized won't be equally powerful, there will be a difference. However, many people prefer to...

Yes, but if you set to high the shuttle mode on Non-SW and set to off it on SW they are equal powerful. My gen4 SW without shuttle mode the peak power is 100W less. Few people use shuttle mode, most people turn it off even in SW, so 720 W is not even 620 W, let alone 666 W.

I promised I wouldn't publish it. But it will be very powerful, I didn't regret buying a Gen4 and not another one with a DJI motor. But call your LBS and they will tell you.

the lbs already know, they were shown what the new fw is like and that it will be released in November. There was a conference, they showed it there. But they are not allowed to tell the users. At least they are not allowed to announce it, but if you ask your lbs they will tell you how many W...

I hope it will be more powerful than the DJI Avinox, because even with my S-Works in Shuttle mode, the Unno and Amflow leave me standing on steeper uphills. 🥵 And we hope that the Levo will be able to switch automatically like the DJI, meaning when I shift but can't pedal because I'm standing...

Yes, it was announced to traders yesterday, but it's still a secret. Ask your lbs ;-)

I figured out why it makes this sound. They left out this bushing on the spindle sprocket side. That bushing is simply missing there. Because of this, the end of the spindle will first start to hang, which is why it makes a clicking sound. Then this hanging will break the rider freewheel and...

I recorded a new video about what noise give out this motor spindle hanging: The motor makes a rattling sound due to the hanging drive shaft (motor spindle) when I pedal above 150 W. The crank is greased, tightened to 50 Nm, it's not making this sound, it's coming from the motor, from...

2.962 kg without: motor and shock and tcu and remote and chainstay rubber protector and rear axle and derailleur holder and other parts, but with : rear fork, battery dock, motor to tcu cable, speed sensor and cable and axs derailleur power cable, and shock link without flipchip

my gen4 makes the same sound. It's because the motor spindle is hanging. Grab the crank by hand and push and pull it sideways, if it's hanging then you have the same problem as me. Or the crank is just loose. Watch my video and check it like this, without the crank:
