For the first 10 hours of the DME being powered on there are several functions in the DME ECU that can be altered via ESys, this includes, the VIN, the ISN(password for creating keys), the mileage, the engine variant (change 335i output to a 640i output same engine different maps), catalytic converter monitoring, and finally VMax (max speed).
The timer begins as soon as the car is turned on and once it elapses 10 hours, usually long before an end user takes control of their car (Euro Delivery excluded), none of these values can be easily changed in ESys by just changing the FDL coding for the functions. The timer can only be reset using specialized tools, ECU Explorer is one example of one of these tools.

Nice explanation. FWIW as long as a car hasn't been sitting long on a dealer's lot and driven a bunch or had the ignition left on a US customer should still have time to modify some of these parameters. Was able to modify Vmax and get it to stick on my 340i. No idea if it actually is removed though as I don't have a road like the autobahn to try it on.

AFAIK the counter starts with the first ignition cycle and continues so long as the battery is still connected. I know many people who've tried with brand new cars with like 9 miles or less on them and not been able to effectively change these values.

Specifically MIL_codierung (CEL suppression), KAT (catalytic converter efficiency monitor), VMax (electronically limited top speed), and mostly for EU users, Vartianten_config (which is necessary to bring limited output engines up to their full output capacity) and also Laendercodierung (Region/Country Selection).

Where to look for those equivalent parameters in CAS ?
In my car I have error:
1F2108 DME, incorrect data record: Variant monitoring

Is it possible to code the CAS with variant compatible with information in DME.

I also have the problem with the variant monitoring. The donor controller has already got the VIN, ISN and programming with Esys. Now it fails because of the coding because the operating hours are exceeded. I wanted to connect to ECU Explorer, but each time without success. Have there still K-TAG but that does not build up any connection, I'm really nothing more about how I should continue. With BMW Explorer I can build a direct connection to the table but that is not suitable for hours reset.

Problem solved, the donor DME was broken.

Flash back to stock and relock dme. Then try flashing the other map again. What connectors are you talking about?

[hieuvietmy]

the dme connector number 2-3
on the dme it have 2 connecter can plug in same
and my guy plug in the wrong position

You can't accidentally flash it by plugging this into the wrong connector slot. Only the one has the proper 2 CAN lines power, ign, and in some cases additional pins. So unless you fried something by running power to the wrong pins you shouldn't have an issue just trying to do it properly on the right connector. If you have an issue then you almost certainly bricked it irreversibly.

Lol yeah I am alive, my BMWs aren't really roadworthy and I haven't spent more than 20 minutes on them in year+ since like last week. Been busy on my house a lot, and on my other toys, it's hard to resist the allure of a 911 Turbo S to work on a full rebuild ya know lol.
