2003 620S ECU data Bad

[mcsputnik]

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.

iaw59 don't need licence for activating buttons

understood, im able to get reasonably accurate data from JPdiag, and dont "need" to register.

However, among other things I wanted to check was that the dash mileage matched.

Was curious if anyone had seen a similar bug, and whether filtering was useful or what ended up concluding.

Also, also I assume if I want to use the ECU map dump (ECU276c) I need to register?

if you want to reflash , you need to purchase a writer licence.
you cannot check the mileage with jpdiag
