2003 620S ECU data Bad
Posted: Tue Nov 11, 2025 7:58 pm
Greetings,
Inherited a monster 620S with a chopped rear end and no Cat.
Plugs are soaking wet, guessing I need to update the ECU map.
However, this is all that gets spit out when I try to register:
IAW59MHW010
00
0000
00 00 00 00 00
LOADF:2.10
20 02 11 26
Pas de n° de série
which is rejected when I submit.
