Always used map 1... I have now a problem each time I want to push the car, I get drivetrain malfunctions. Tried to attached a pic and the limit of the forum is too low so I canít.

Errors I get when pushing it harder than 50% throttle:

These errors are from the JB4 app and none of them have available descriptions.

Basically I canít use the car like I would want to with the JB4 installed, I could push it harder before I had it, so, kinda like a waste of money and time for now and until we can figure why itís causing so much errors and particularly drivetrain errors which makes it go into limp mode.

The only log I could do is in attachment, but. Itís not much since itís going into limp mode all the time.

By the way, the install was done by a professional, so I doubt he messed things up but hey, could happen.

Thank for your help
