This means that it will be ready to "get married" to your car's security system, also called EWS. This procedure is also called doing an "alignment" or "synchronization".

General Technical ECU Troubleshooting Guide
In the industry there are many BMW ECU programming. We wrote a guide to help answer and give you solutions to some of the most commonly asked questions.
We have reverse engineered these ECU's and developed proprietary Equipment that allows us to Re-program used ECU's to your car's VIN Number.
Because if you install a used ECU in any BMW, the VIN number and "Rolling Code" will not match, and it will prevent the car from starting.With a used ECU the car might crank, but it will never get the "permission" to power the fuel pump and send the spark signals.
BMW's have the EWS Module (anti theft device) that has a password feature called the "Rolling Code" which changes between the DME and EWS every time that the car is turned off. This makes it virtually impossible to swap used ECU's between BMW cars.
"NO". Our Exchange ECU's will be programmed to your BMW's VIN number and correct application. However, due to the fact that the EWS systems have a random "Rolling Code" we can't guess what this random code is. Therefore, we reset this feature to make the ECU "blank".
In order for the rebuilt ECU to work in the car, a ECU to EWS Alignment/Synchronization has to be carried out.This is done using a BMW scanner like a GT1, ISTA, Autologic, Launch X431,Baum Tool DS2021and others. It takes less than 5 minutes to "MARRY" the ECU to your car, and once that is done the ECU is ready to start in the car.
NO. ECU re-programming is not required because most repairs are done on the hardware parts and not on the software programming. Once we repair your unit, it will be 100% "Plug and Play" already tested in our actual Tester vehicle.
