So I did NOT change the daten files – I left them as they were after installation. I compared these existing daten files with the daten download they have for the E85 chassis, and they looked identical (same # of files, same sizes, same dates, etc.) in the important folders.

When I installed the Standard Tools from bimmergeeks, daten were already there. NOTE: All download sources, including bimmergeeks, provide a separate download for daten. (revtor's guide is introduced in Post 2 of 3: Coding) NOTE: Additional details around steps 4-7 provided in revtor’s guide, page 32.

There is a switch built in, set it all the way to the right.ġ. I am not going to spend the time to un-bridge the pins just to see whether they MUST be bridged.Ģ. Once I got good software, it worked with the pins bridged. I bridged the pins a couple of years ago when I could not connect with my vehicle (root cause: bad software download) and was trying to rule things out. NOTE: I do not know if you MUST bridge the pins with this cable. If not, make sure to set the USB port being used to COM1 and Latency Timer=1 for each new USB port that you plug into. NOTE: MAKE SURE TO ALWAYS USE THE SAME USB PORT. Set the cable to COM1 with a Latency Timer of 1 in Device Manager. Your mileage may vary here - you will need your PC to recognize the cable as an OBD interface. Windows automatically downloaded drivers when I inserted the cable into the USB port. Google bimmer$0ftw4re but replace the characters with the appropriate letters. I bought the cable from - Website gets blocked. This does not mean these choices will be guaranteed to work for you with your PC and/or vehicle. I will provide information for what I have CONFIRMED and VERIFIED has worked for me to code my 2007 USDM Z4M coupe using a Win7 laptop. For other cars, make sure you select the corresponding chassis code. I will refer to E85 moving forward, but the instructions apply to any E85/E86 variant. Note: With coding, all E85/E86 Z4 models are under the “E85” chassis. This guide should serve all E85/86 Z's, with only some minor modification for other chassis needed. I know there are a number of these walkthroughs around various bimmer forums, but I still had a hell of a time working this out, so one more will be useful to someone, I'm sure, especially for us Z folks to have one specifically with the Z in mind.
