After installation and the JB4 App is purchased, your friend should see a connection error.

Thanks Terry. It only does it in "Auto" in Standard Mode, and only when not fully-warmed up. When I use the paddles or shifter in Manual mode, it shifts quick. I unplugged the JB4 and had the...

Terry,

This may have been asked before, but is there any way to get Oil Temp via the JB4? It would be beneficial to know for when to safely "exercise" the motor after a cold start.
