Hope this helps.
I got this statement when I asked Eurocharged why wasn't my stock ECU read during the tune.

Unlike Lamborghini or Ferrari, BMW uses only a handful of software calibrations for each model car. This means that your "stock" software is identical to 1 out of 6 BMW's with the same model. Since this version was already on file and matched your software 100%, there was no need to waste 45 minutes reading it out.
Is it correct that 328i only has a handful of stock software versions? Is it critical to read the initial stock file in order to restore my car to the exact factory condition? From reading your posts, it seems every car's ECU is different?
