I'm considering doing the Alpina D3 software flash on my 335i and am curious as to whether I'd need to remove (unpair) the Cobb tune prior to flashing or not?

Also, do most put a battery charger / trickle charger on while flashing? And if so - do you connect to the battery itself (boot) or the terminals under the bonnet?

Thanks!
You are doing the Alpina B3 flash right? If you battery is suspect then a battery charger would be necessary and you can use both the front or the back, if not just make sure all accessories are turned off...YOu have no issues coding with Cobb and no need to unmarry it...If your using JB4 and Procede just make sure you put it on Valet mode and you should be fine...
