Bought the bike new in spring 2025 and have this error message from Nov 2023 WARNING - The drive unit setting(s) have been modified by unauthorized software : Drive unit output feature Current setting (change to 11/20/2023 11:11 AM) Destination : Type 1 Tire circumference : 2300 mm I find it strange...
That warning is Shimano's E-Tube software flagging that the drive unit was, at some point, connected to something other than official E-Tube software - it's a trust flag, not proof anyone actually changed your settings. Community members here have hit exactly this: a member reported the dealer's diagnostic report showed "Warning - unauthorized tuning detected - drive unit output feature" even though it was never tuned, it only read the data once with the "basic" ST-Unlocker, and another poster clarified "Unauthorized tuning detected" can simply mean that something non-Shimano (like the ST-Unlocker app) was connected to the motor. That's all it takes - it doesn't specifically mean you have to change parameters.
On your specific values:
Type 1 destination and
2300mm circumference are standard EU-spec settings for a 29" wheel - nothing exotic there, so if that's all the log shows, it's likely just noise rather than evidence of an actual detune or speed unlock.
The odd date is the part worth flagging to your dealer rather than shrugging off. 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)
- as forum regular
@Backflip's post explains in more detail elsewhere, Orbea's own RS tuning is a legitimate, Shimano-sanctioned factory process, so it shouldn't itself trigger this. A log entry timestamped Nov 2023 on a bike sold new in 2025 most likely means the drive unit itself was manufactured/bench-tested that far back and sat in Orbea's or a distributor's stock before being built into your frame - drive units don't have their own live calendar clock until first paired, so a factory test event can carry an old timestamp. It could also mean the unit passed through another hand (demo stock, a returned unit, pre-owned before you) before reaching you as "new."
Worth doing: ask your Orbea dealer to pull the full regulation change history (not just this one line) via E-Tube Project Professional - if every torque/power value shown matches the stock Orbea RS profile, you've got nothing to worry about. If any figure looks off from the standard EP8/EP801-RS spec, that's when to push the dealer for an explanation before it becomes a warranty argument down the line.
