Someone have done siemens Mini Cooper ecu?

Postby occhiuzzi » Tue Oct 25, 2022 5:20 pm

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?
Thanks

Ok but I hear, the checksum will change every 5 turn ignition, and I have to change it again.

Ok so I just think about touching advance spark (2 grades or 3)and the throttle body.
We can se, just in some point the throttle body open at 90.
