It rained a lot today but Iíve had the jb4 for almost a year and drove through snow rain nothing ever happened, but today I noticed big power loss and boost gauge not working and afr not working, but the funny thing is I can still change maps through the bc stalk and other options and Iíve tried changing maps and boost gauge and afr options, no difference if the jb4 got wet and damaged how does it still communicate through the obd2

Open the enclosure and if the board looks soak or rusted, fix the leak, and replace the board.

Is there a better casing for jb4? Once you start to add ewg and ff wires, jb4 doesn’t close fully. So i just zipped tied it and zip locked it.
