I'm getting this foul burnt smell using the jb4. Has anyone had this issue? Not driving it TOO hard. Not even in sport mode. Why is this happening?

 

Don't have the JB4, have Dinan but have used JB product before.

Have you checked to make sure wires aren't burning or rubbing against something. Also sniff the control unit to see if it has that odor?

 

Not a bad idea. I'll do that tomorrow.

 

As Minnie said, make sure the cables aren't touching anything that's burning hot. While I don't have a JB4, I do have an NM Power Module, and have had no such issue with it. This is the first time I've heard of someone having a burning smell while using the JB4.
