Battery question
I had to replace my battery in my e55. It has a pulley and tune and my question is does the ecu hold the tune when the battery is disconnected?

I will check the aux battery as well. That's good to know. I have the tune on my computer but I wasn't able to get to it at the time I replaced my battery. Thanks for the help.
