NCS Expert: Basics To Reading And Writing To Modules

in NCS Expert Software | 1 comment

As you may or may not know, NCS Expert is simply a program used to read and write (program) parameters to a vehicle. Below is a basic flow chart that shows one of the methods a person might use to read and write information to a module (computer location) in the vehicle. Step 1 Selecting the Chassis type simply tells NCS Expert what type of vehicle it is dealing with so it can retrieve your car’s VIN number. For us that own an E90, we will always choose E89. Step 2 – 3 Some have mentioned that Step 2 is not that important, and that you can select any of the ECUs (CAS, FRM, or NFRM), but it has become a common practice to just select the CAS module. We need to select one of the modules so that NSC Expert can pull the vehicle’s VO (Vehicle Order). The VO is simply a string of numbers that represent what modules are installed in your car, where your car was made, and other useful information needed so NSC Expert knows how to code your car.  So once you select the module, you will notice beside FA a series of numbers and characters. This string of data if basically your car’s DNA. One of the most important points to remember is, the module selected in Step 2 has nothing to do with the module/s you select in Step 3. Selecting the module in Step 2 is used to only pull your vehicle’s VO. The module you select in Step 3 is the module you will be reading or writing (programming). This is something that confused me and others for the longest time. Another important point to know is, once you select a module in Step 2, and NCS Expert reads your VO, it will also store a copy of all the parameters programmed in every module in a FSW_PSW.TRC file, located on  your computer in the NCS Expert WORK folder. If you are confused about what the FSW_PSW.TRC file is for, that’s okay, let me try to explain. NCS Expert was programmed to create/write the FSW_PSW.TRC file automatically to our computer when it reads information from a module/s. NCS Expert gives...
