Yes you do have to keep the OBD plugged in. That is how the unit itself gets power to operate. As far as uninstalling, it shouldn’t take but a couple minutes, and same with reinstall.
Hey everyone! I just wanted to put this info in a thread, that I’ll keep updated as best I can. I’ve copied and pasted the current JB4 maps from v14. This is from Burger themselves
Map Guide as of v13+ firmware:
Map0: Stock tuning, fully disable JB4
Map1: Additive map with peak of 3psi over...
I think I might actually go jb4 until obd flashing is figured out again. I want to use the mhd I have, but I really don’t wanna have to pull out my ecu and not be able to drive the car lol
