I can only connect VisualME7Logger after having connected Unisettings one time (read params).
I cannot connect with only IGN on, I need to go through Uniseetings first.
Once connected, I can see the values updated in real time, so CFG and ECU file are ok

Of course, once connected with VisualME7Logger, if I try to crank it up, the engine dies as this is the normal behavior after Unisettings connection.
If I cycle the ignition, the engine starts but unable to connect anymore VisualME7Logger and you cannot go through Unisettings when engine is running ....
Chicken and egg ....

Error! Exit code:4
=>could not connect to ECU, exiting ...
exiting (cause=0x4)...

I succeeded in connecting with IGN ON using SLOW-0x00 aka double init (btw, I can hear the 2 consecutive bips coming from the cluster, as for connection with UniSettings).
BUT as soon as I crank the engine up, more precisely, as soon as I release the startup key, the values freeze (so connection dropped).
I tried various speeds without success.
Sometimes I got popups like the ones attached.
