Hi guys, I have to do a map for this ecu.
Hw118012003B for a mini Cooper ("year 2001?).
So I hear something like mini change checksum every 5 start engine, so how can I write it? I read it with less and I wanna write it with kess, but I'm a little bit scared about it.
Can I just put a charger, or connect a secondary batteri, or I need absolutely a charge manteiner?
