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 stock added (91 octane)
Map2: Additive map with peak of 4psi over stock added (91-93 octane)
Map3: Additive map with peak of 6psi over stock added (93+ octane)
Map4: Additive map with peak of 6.5psi over stock added (93+ octane)
Map5: Additive map with peak of 6psi over stock added & more aggressive timing profile for higher octane fuel (experimental, 93+ octane, bolt on modifications)
Map6: Custom tuning map allowing both additive (below 10psi) and absolute (above 10psi) targeting
Map7: WMI map (boost varies based on WMI additive and map settings)
Map8: VALET / Low Boost Map

Do you have to keep OBD plugged in? How hard is it to install & remove & before going to dealer?

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.

Threading the OBD cable through the firewall was only on initial install. I just unplug the OBD cable and stuff it in the back with the other electrical wires. And then unplug & remove the JB4 from the engine bay. Been to the dealer 3 times (free oil changes & recall) and haven't had an issue, and I doubt they will notice it hanging out as this is the same dealer that couldn't figure out how to get Odometer to display on dash!

Did you purchase the EWG connector or the Fuel Pressure connector?

From my reading and communication with Burger, those are only needed for the higher maps and after consulting with them (sending logs for review). Got big plans?
