Bren/BMW software/firmware update
Just a quick reminder for anyone planning to get a Bren tune (myself included). Make sure there aren't any open bulletins or updates available first.
I was at my dealer over the weekend, and just happened to ask whether or not my '18 GTL was up to date. Apparently, I missed an update notification
from BMW back in JANUARY!!! (I don't think I ever got it). At any rate, I had planned to send my ECU you in before that. Fortunately I asked, or I would
have had to pay Bren $99 to re flash it after BMW's update wiped Bren's tune.
Never enough garage space.
