eTuning Shimano - error in Shimano E-Tube: Unauthorized modification detected.

[l3moncho]

Back in 2021
I wanted to have assist up to 32km/h, which turn out is not working good for me, so I did reverted back to 25km/h
I did that using eTuning | Ebike Tuning App for Shimano Steps Motors
Now a days I got the original SM-PCE02(reasoning why got is bellow) and when I connect I got error messages "Unauthorized modification detected."
My question really is: is there a way to revert all to stock and remove that "Unauthorized modification detected." ?

I had to go to with SM-PCE02 because I had to troubleshoot errors related to speed sensor & magnet - that's something for another thread, because I ended up stacking more magnet on top of the original Magura MDR-P CL rotor




PS just tried to contacting the app company at Contact - Etuning
to see if they going to reply

Most probably your bike is still programmed to US mode (because you can increase max. speed to 32km/h like seen with the blue button).
You have to program it back to EU mode with E-Tuning app (and not just reduce the max. speed to 25km/h).

Thanks Mate.
Wonder do I need to downgrade again to exploitable version with E-tuning app :/
I’ve written email with the guys and they claim this is not due their app, but rather Santa Cruz custom setting of Mx wheel, which I found to be quite misleading

The red warning is definitely to the incorrect region / destionation setting, otherwise the text in the red warning would have be different:

If you read an analyse this red warning text thoroughly, then you will instantly see the reason for this warning: So, in this case it is "Destination". And yes, you most probably have to downgrade again, so you can reset the region / destination to the original setting. Don´t trust other "self claimed professionals" or rumours...

 

[l3moncho]

Thanks mate!
Do you happen to know a way to change the region at the current version?

the downgrade was pain in the ass

The reply I got was from the official support email of those guys(E-Tunning app), which is odd

You have a PCE02 cable so you could purchase STUnlocker otherwise you’ll need to downgrade. On my motor the original setting for destination was ‘Not Defined’. Not sure whether there is any way to reset without the Windows version of STUnlocker or the much more expensive e-max tuning.

I just bought a used Merida eSpresso 300 SE. It has a E5000 motor and a SC-5000A display. I also have a SC-E7000 display on my other ebike (merida e160, ep8) that I have derestricted with stunlocker.

If I want to derestrict the eSpresso 300 and I just temporarily connect the sc-e7000 display/controller and then connect via bluetooth and unlock?

Or is there something I haven't thought about.

Its the worst company out there they double charge u says it's incomparable then ignore you

 

[ottoshape]

Its the worst company out there they double charge u says it's incomparable then ignore you

What?

 

[steveone6]

What?

What what ?

 

[Backflip]

What what ?

So, what exactly is the worst company out there and who does double charge you and says it's incomparable and then ignore you???
Which company are you writing about - at least (also) for me, this cannot be seen in your post...
Sorry I am not a native English speaker and I (also) have difficulties to understand your post...
So, please be a bit more precise and detailed so other forum members also can understand and follow your thoughts. Thanks a lot.

Etuning app ?

Etuning app ?

Youve heard of etuning it was mentioned in this post that why I mentioned them

Thanks for clarification.
Yes, it is my opinion too that eTuning is a crappy piece of software with poor customer servive...

So l3moncho, did you figure out what's the root cause?

I am just facing similar / same issue on friend of mine YT Decoy.
We figured 32kmph is not worth to miss v4.4 Race-Specific features and for few weeks we do fail to make the EP801 "defaulted"

Going to use STUnlocker to see if it helps.
Yet, it's 20E for E-Tuning, 30E for STUnlocker... wow

"Race specific" features were introduced on motor firmware 4.3.0 for the DU-EP801 (not "4.4"), see here go down to “Firmware Updates” and then use “Filter by Model No”, then “DU-EP801”.
Also, you cannot speed up a DU-EP801 (and DU-EP600) based bike via STUnlocker or E-Tuning, because these 2 software products do not support these new generation drive units from Shimano.
However, you can use eMax-Tuning (see here) to speed up a DU-EP801 or DU-EP600 based bike. Works like a charm, as you can see in many forum posts in this forum.

Yeah mate, you are right - realized it the hard way! Japanese did it once again, confusing customer with overcomplicated naming convention (look at Sony headphones naming)

I was NOT comparing apple to apple as my friend has YT Decoy with DU-EP800 (the latest FW 4.2.0) and I have Orbea Rise LT with DU-EP801 RS (the latest FW 4.4.2)

The bottom line now - I did downgrade DU-EP800 to 4.0.2, used E-Tuning to fix the Destination (Type 1 - EU) and Wheel Circumference (2300 - 29"), saved stats, connected SM-PCE2 and:

- Opened E-Tube Project Normal v4, saw all good
- Opened STUnlocker Win11, read values, all good
- Opened E-Tube Project Professional v5 and saw "UNAUTHORIZED MODIFICATIONS DETECTED - Destination (Type 1), Circumference (2359)"
- Opened STUnlocker Win11, read values, all as expected (Destination Type 1, Circumference 2300)

I got confused, used E-Tuning again and set Destination Type 2 (US - 32kmph) and set Wheel Circumference 2359, saved and:

- Opened STUnlocker Win11, read values, all good (US + 2359)
- Opened E-Tube Project Professional v5 and saw "UNAUTHORIZED MODIFICATIONS DETECTED - Destination (Type 1), Circumference (2359)"

So we decided to forget about E-Tube v5, set things to user's liking (32kmph + 29" circumference) via E-Tuning, upgrade DU-EP800 to 4.2 via E-Tube Project v4 and checked it is all configurable via E-Tube iPhone app.

The hell is wrong with E-Tube Project Pro v5?
I have no idea, but the job for YT Decoy is done ...

Thanks for clarification - yes, please always compare apples to apples and don´t mix drive unit types in the "Shimano universe"...
And "yes", it is a shame that Shimano has named the older DU-EP800 and the newer DU-EP801 on the right motor cover with the "EP8" signature which caused a lot of confusion (even on many bike manufacturers), because these 2 drive unit types have next to nothing in common and are hugely different!

Also there is nothing wrong with E-Tube-Project-Professional version 5.x.x.
However, you most probably did not read the red warning correctly and in depth, because the exact wording of this red warning will give you a clear hint to the real reason why this red warning is shown!
So please post the red warning here as a screenshot and I will tell you what you have to change to get rid of that red warning. Most probably the red warning is NOT due to the destination setting and NOT due to the wheel circumference setting but due to some motor characteristic settings (e.g. individual torque values which are not accepted by Shimano).
It is very common that you e.g. will get a red warning like this with the wording "Drive unit output feature" which clearly indicates the situation described above:

So, take your time and always read this red warning with some patience and then you will exactly know what you have to do to get rid of this red warning message.

Also you always should create a so called "service report" with the Windows based E-Tube-Project-Professional software (use the lower left button in the "MAINTENANCE" view) and then check this PDF document for "unknown" values. You also can post this service report here and I will tell you what (still) is "wrong" with this bike.

See e.g. here for some settings with "Unknown" (individually set via "non - Shimano software") torque values for Eco and Boost mode in "profile 2" in the service report which will cause the above red warning:

So, just use the E-Tube-Project software (Bluetooth based Cyclist app or Windows based Professional program) and set these values back to "well-known-Shimano" default values and you will not get this red warning anymore.

Oh

Didn't expected so thorough analysis can be done here (on forum) so next time I hook up the Diagnostic I'll get the data - thank you

However, I am fairly positive the warning was for Destination and Circumference. And that v4 did not show any of these.
Anyways - the task failed successfully and as we primarily realized no RS features are available (no 4.2+ firmware available for DU-EP800) we gave up.
Per rider the motor works just fine and have no errors either

but damn you raised my curiosity ...

Thanks for your nice reply.
I am 100% sure that if you have programmed the county destination settings and wheel circumference settings to the values shown in the latest regulation log and there is still a red warning shown in the Windows based E-Tube-Project-Professional 5.x.x, then you have an issue with the motor characteristic settings (indicated as "drive unit output feature" in the red warning signature).
And "yes", the older Windows based E-Tube-Project version 4.x.x does not show this red warning...

However, don´t again mix things and ideally don´t use abbreviations which can lead to misunderstandings: "RS features" is a wording which can easily create confusion.
There are the reduced "RS" settings for max. torque range and max. peak power on Orbea bikes (with DU-EP600, DU-EP800 and DU-EP801). These setting are not firmware version related, see e.g. this forum post of mine.

And then there are the commonly called "race mode" features ("assist carry over", "aggressive Boost mode", etc.) which were introduced solely for the DU-EP801 with motor firmware 4.3.0.
These "race mode" features are and will never be available for a DU-EP800 or any other Shimano STePS drive unit type.
