ECU Removal

Is there a guide on how to safely remove the ECU from my 128i?

Not that I'm aware of - why do you want to remove it?

Ah...forgot there were still tunes that require sending the ECU out for updating. Once you get all the covers off and the connectors disconnected, it should be relatively straightforward. If you do some searches on this forum, you may be able to locate a step-by-step or video on most of the process, such as installing a JB4 or Procede tune on a 135. You can also go to realoem.com and look at a diagram of where all the parts go as well. Just be absolutely sure the battery is disconnected before you start. :-)
