This is to *read* the ECU, not to *write* to it. In my case, I wanted to modify something in my GM5 moduleġ5, IMPORTANT, make absolutely sure that the JOBNAME = CODIERDATEN_LESEN. Mine seems to work with either of the top two, I choose ALSZ as that one has always worked for meġ2, Hopefully it worked, NCS has now read your car chassis number & some other things (I have blanked mine out)ġ3, Click Process ECU button (or press F4 key)ġ4, Another box pops up, time to choose the module you want to code. Choose whichever one works for you, it doesn’t matter which one you select, this has nothing to do with which module you are programming, its just to get NCS to talk to your car. Choose E46!ġ0, Another box pops up straight after, choose your ECU. I’m using Expert 4.0.1ħ, Once loaded, click bottom left button (or press F1 key)Ĩ, Then click 3rd button from left (or press F3 key)ĩ, Clicking that button will enable you to choose your chassis. Goto File > Load ProfileĦ, Select the profile. If it is connected, you’ll see Battery & Ignition dots are both black at the topĥ, Close INPA, then open NCS Expert. Ignore the fact my plug is hanging out my car, I had to remove some of my interior panels for another job, and I haven’t put them back yet! The plug is usually found under the dash, above the accelerator pedalģ, Turn ignition of the car on (the position before actually running the engine)Ĥ, Load up INPA to make sure its connected. It should light up blue once connected, even if ignition is off.

With that said, here’s my guideġ, Get into car, ignition off, plug in lead. However, there were no instructions on how to use or code with NCS Expert, hence this article. It was delivered next day, and the installation instructors provided with the software was very good, there is no need for me to repeat them here. I bought my cable & software from Cable-Shack. This is purely how to physically use NCS Expert, and how to read & write to the FSW_PSW file in order to change settings & functions on the car. I’m not going to go into how to install NCS, or what parameters to code in this article. After repeating this process with success several times, I am now confident enough to write this article to hopefully help others. I am by no means an expert, but I have recently got the software & a cable to code on my E46, and I struggled for quite some time on finding a really in depth & detailed how-to guide. This is, hopefully, the most complete how-to guide for using NCS Expert to code a BMW.
