Alpina D3 software - Remove Cobb?
Quick question, and I think the title says it all.
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?
