Has anyone try using a PearTune or SpeedBox module on a Shimano EP6 or EP801 motor?

Warning!!
Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.
Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.
We advise members great caution. EMTB Forums accepts no liability for any content or advice given here.
Shimano EP6 / EP801 with PearTune or SpeedBox

None of the above....but I use eMax tuning software to get higher topspeed assist, full.power torque and working AutoShift.
So you have 11 speed?
Yes....LinkGlide 11 spd deraillure XT DI2 SHADOW PLUS RD-M8150-11, shifter SW-M8150-I and computer/display EN600.
The shifter is not absolutely needed, but I like to make manual shifts anyway.
The shifter is not absolutely needed, but I like to make manual shifts anyway.
The eMax software can (on EP801 motors):
- set speed limit to 50km/h (or is it 60 ?)
- set power to max 600w
- adjust wheel size if needed.
- some other stuff.
I set it to:
- speed limit 32km/h.
- power max 400w.
- enable electric shifting.
- rear sprocket max ring size: 50
Yesterday I went on a 32km ride, and it completed and at the end i had 32% battery left.
Bike: Orbea Rise M20 2023, upgraded fork, wheels, steeringbar, pedals, battery to large.

No....using the Windows version is step 1.
License is 119 euro (100euro plus VAT)
This is currently not a DIY job.....maybe in a later version.
The german (very friendly and very helpfull) tech needs to be connected to your PC via AnyDesk (free and no installation needed) and do his magic.
It takes a couple of minutes, and he will communite on your pc in Notepad.
You can follow his steps.
When this is over, I'm using the mobile version in the trails (version 2.40 currently)

Exactly.
Wow, speed limit 32km/h, 32km ride and 32% left!!! Are you by chance 32 years old?
It’s because he’s on 32” wheels with 32 gears. The motor was probably averaging 32nm of torque.Wow, speed limit 32km/h, 32km ride and 32% left!!! Are you by chance 32 years old?
And I'm sure it was really hot that day like...32 degrees, no?
Yes! on the 32nd of July…..

Hi, does it work with Ep801?

I have been using the PearTune module on my EP6 motor for about 200 miles now with no error msgs, once I get to 500 miles I will say it's works. With that said the EP8/EP6 are the same motor/firmware tune from what I have read, just cover material is different. EP801 has different firmware tune, so not sure if it will pickup the PearTune module.
What's the part number of the Pear Tune module you are using?

Here the link PearTune MSO Tuning elektrokola Shimano EP8 |Pear Control
The diagram on the website is of a E8000 motor, but they will send you the diagram of a EP8 motor with the module.
eMax software tuning works excellent with EP801.
Currently on 1500kms without issues.
Using an external electronic hardware box (like SpeedBox, PearTune, MBIQ, BadAss, RedPad as well as Planet3 „mechanical tuning“, etc.) which will manipulate the signal from the speed sensor will definitely not work on the new generation drive units (DU-EP801/DU-EP6) and for sure will generate E295 and finally E299 errors sooner or later and finally will completely block the motor support!
In this case Shimano has to unlock the drive unit and this is a highly time and money consuming process.
Also you will never get rid of the E299 and so your bike most probably is already flagged for out of warranty for a lifetime, even if the drive unit was unlocked again by Shimano.
It is very easy to detect such manipulated speed sensor signals for the Shimano motor firmware via their new antitampering algorithms which are built in the motor firmware., see e.g. here.
So, don´t try to use such "dongles".
Also don´t get fooled by some manufacturers (like PearTune) of such "dongles" if they advertise and claim their product as "EP8 compatible", because the wording "EP8" mosty creates major misunderstandings => Unfortunately Shimano has branded the new DU-EP801 (released end of 2022) and the older DU-EP800 (released in 2020) on the right side motor cover with the “EP8” signature.
However, the older DU-EP800 and the newer DU-EP801 are completely different types of drive units in mechanical, electronical, firmware and software aspects.
To visually distinguish these two motor types, you can have a look at this German forum post or also this one.
The only way to speed up a DU-EP600 or DU-EP801 based bike in a long lasting and absolutely errorfree and hassle-free way is via a purely software based tuning!
Check eMax-Tuning for this and maybe also search for the solely positive ratings and feedback posts of eMax-Tuning (e.g. in this forum).

Yep that is a Shimano EP6/EP801 fact, if the motor detects any oddity in the rear wheel sensor and you will get the E295 error:/ I was using a PearTune for the EP6/Ep801 and had the E295 error a couple of times, so I when with the ePlus flash software and converted the EP6 into a class-3 28mph, no issues so far.
Thanks for your reply and information.
However, after PearTune (where you also have thougth "everything seems to be fine" according to this post and didn´t realize that it will throw E295 errors, which btw. you cannot clear...), in my eyes you again have backed on the wrong horse with EPlus, because the Italian guys from EPlus obviously felt pressurized by eMax-Tuning (because eMax-Tuning already does DU-EP600 and DU-EP801 optmizations flawlessly since more than 2 years).
So EPlus seems to have created a "quick and dirty" solution for US class 3 mode (with max. 45km/h) which they finally have released in April 2025, but can leave your drive unit in a problematic state in which you e.g. cannot reset this US class 3 state anymore (in case of a warranty issue or if you just want to go to a regular service appointment).
Also take in mind that (in comparison) to eMax-Tuning, the EPlus solution is "server based"!
So, if (for whatever reason) the EPlus server will be taken down (e.g. by Shimano due to legal enforcement), you then have no way to reset your bike to the initial state and so are left with a bike without any warranty.
With eMax-Tuning, you easily can do this reset by yourself in an offline mode and no connection to any internet server is needed for this.
Have you ever compared the quite poor ratings of the EPlus apps in Apple´s AppStore and Google´s PlayStore(see e.g. here and here) to the excellent ones from eMax-Tuning, see e.g. here and here? I think this tells a lot about the differences...
In my eyes EPlus is just trying to sell tuning products for anything and everything and is not focussing on important details and working with love on these things.
eMax-Tuning is doing software development solely for Shimano STePS systems since many years and is caring about customer service at its best.
BTW.: The eMax-Tuning solution also is cheaper than EPlus.
For sure everybody can decide by its own and I seriously hope that you will be happy and hassle-free with the solution you have chosen.
Just my 5 cents.

Thxs for the info on the differences between eMax & ePlus software. My EP6 is out of warranty and I don't plan on rolling back to a class-1 eMTB. I have looked at the eMax website, but they don't have any information on their software works with a EP6/EP801 motor. I may download the eMax software and see how it works.Thanks for your reply and information.

Thanks for your speedy reply.
See here in the "support" section of the eMax-Tuning - website where there are a lot of documents.
Especially in chapter 12 of the latest version of this document you will find all information related to the DU-EP600 and DU-EP801 drive units.
Also there is always up to date information in the "news" section.
BTW.: Even if you are officially out of warranty, Shimano sometimes may replace your drive unit free of charge on "goodwill" (at least if you will bring back the drive unit to a traceless initial state before sending it to Shimano).
However, this mostly depends on the mood of the employee who is dealing with the case.

Emax software is easy and I have set both Ep6 and EP801 to US class 3 without problems.
