I don't know what is causing SGII to wake up after engine stops. I presume it reads some code from the ECU. We can investigate this issue together when we'll meet I have oscilloscope and two diagnostic interfaces so maybe we'll find a solution if SGII hanging is caused by any electrical noise or something else.
Longest weekend of Modern Europe is coming so we can try to meet and investigate it. And we've planned to meet anyway so maybe we can try to kill two birds with one stone
