Ok, I will bite since no one has asked this more specific question regarding dealer detectability of any ECU “tampering” after using this device. I will ask this question using this basic scenario….
1. You purchase a car new off the showroom floor (one that is supported by the device now or in the future), bench unlock the DME and make a mirrror/backup of your DME shortly after the break-in period, say at 2000 miles. 2. You then tune to your hearts content, without any issues or engine damage, etc. Or maybe you do have a “problem”, but get it properly repaired by an Indy shop. 3. At about 10,000 miles, you bring your car back to the dealer for its first, included, routine oil service. Prior to doing so, you flash the DME back to stock, using the unmolested, stock backup/mirror tune created at 2000 miles…. Other than the mileage difference, there are other differences, stored in other ECUs in the car, from when the car was at 2000 miles vs now at 10,000 miles in this example. Assuming the dealer is looking, wouldn’t the dealer be still able to detect those differences, however slight, thus suspect potential engine DME tampering? So while the engine DME may be “fine” but when compared to the rest of the car, there could still be some “irregularities”. I like what this product has to offer (and I don’t even have a car that “needs” it yet ). The potential “risks” of using this device, do not appear to be very significant. After all, the saying “you have to pay to play” is still applicable to this device (even though the price seems very reasonable). But I like to understand exactly what those risks are or may be, no matter how slight, before I would jump in to something like this….

Does my 2020 F95 fall into the “pre 2021” line? I had a late model ‘20 F95 that requires a bench unlock.

The RS functionality is part of your OBD flashing, and this is the Backup/Unlock/Flashback physical device. For RS questions, I would reach out to your tuner. Quote:
Quote:
Functionality During the initial scan, a function AG9999 known as 'Tuning Detection" reads the vehicle data and extracts info including "plug and play variante suspected ", "plug and play DTCs suspected", and "tuning DTCs detected". With 11 of such parameters (was 9 just few months ago), the tool decides to either mark that DME is "Suspected of Tampering" or not. Example Customer A: Comes in for turbo replacement to a dealer. The initial scan is ran, detecting "Plug And Play variant", aka any piggyback. The flag is set off only internally (since PnP is a level 2 detection currently). Now that data is transmitted to BMW warranty sector that will take that into account when issuing warranty repair orders. Since PnP flag can be set off ONLY by having actual piggyback (ok resistor trick with basic board can set it off as well), the warranty is denied even though the car looks fully stock. Why? Well because this specific flash has only one trigger function, that takes into account acceleration! So if you accelerated much faster then stock (letes hope you did, otherwsie the piggy-back did not actually function) and function detected other key parameters, this will be set off. BMW will also have access to "blackbox" data that outlines what performance paramaters (new one added is RPM/s, or RPM acceleration rate) were taken into account. To summrazie, you are screwed. Example Customer B: Comes in with an identical car setup and the same complaint. The scan is ran, and no Flags aside from small chance of "low-Ilevel" is triggered (also level2). At this point, by perfoming Flashback, you lowered your detection chances from Flash to Piggyback, as to say. Now, this is where it gets very interesting: Unlike "pnp detection" that has only 1 trigger point, "low-Ilevel" has MULTIPLE with no "logs" as to what set it off as to say. So BMW now has a huge burden of proof to state that you performed some monipulation OR you had the car repaired somewhere else aside from their authroized dealer network (which you have full right to).
Just with that above, you minimized your flagging risk from pretty serious to barelly any. Now, we enter a 3rd and most interesting aspect: The way it sits, M-Link has ability of performing backup unlimited number of times on your vehicle. With our upcoming updates, Version Control will be relased, and part of functionality will be lowering above mentioned risks even more. This function will alllow you to backup and restore to specific Verson so you have no way to even set off "low-Ilevel". Flow/Scenario:

Thank you for releasing such an awesome and much needed tool! Makes it much easier for at-home-mechanics to service their cars without having to wait for the DME Toby be sent back from a shop.
Does this work for all engine types? Or do we have to specify the engine we will be unlocking when we purchase? Thanks |

I have a 22 m340 and I had planned to send my dme out to femto at the end of this month with this being released I’m reconsidering now.. I’m assuming that the flash back function would only work on an untouched ( non femto unlocked) dme? |

If purchased choosing unlock only option but we’ve already purchased a tune through you and selected the eeprom backup does that transfer to this to be able to flashback or are we required to purchase the super license license.
Also. Any update on the app release so that remote start can be used without keeping key card in tray.. |

If I have multiple cars that need to be bench unlocked, how many times can the license be transferred between vehicles? Can you elaborate on how that system works?
