Hey guys,

The MINI B38/B48 JB4 is a new CANbus enabled tuning system offering a lot more features & function than our previous Stage1 system. The CANbus data allows us to provide more comprehensive and dynamic tuning, advanced features like code read/delete, in dash map switching, boost targets by gear to improve traction, an in dash boost gauge, and much more.

JB4 Interface: Latest Interface Download. When updating your interface you may need to first go to "add remove programs" and "remove" your previous JB4 interface.

'***************************************
'OBDII In Dash Menu

'***************************************
Exhaust Valve Mode:
'***************************************

Toggle between flap open, flap closed, and OEM operation, by pressing the button for 2 seconds and letting go. The left blinker will flash for valve open, right blinker for valve closed, and both blinkers for OEM operation. The valve setting is persistent and will remain in effect until you change it. If you hold the button too long you'll jump in to the in dash menu system below.

Dash mode: By pressing and holding the BC button you'll enter dash mode. The left blinker will turn on and the tach/speedo will drop to zero. To toggle through menu systems press and release the BC button. Note as the speedo modes with each BC press it will not necessarily align with speedometer needle position. The speed = 0 starting menu is for maps with the current map being shown by the tach needle. To change a setting when on the menu you want to change press and hold the BC button. The right arrow will light up and now pressing the BC button will move the tach needle to let you change settings. When the needle is aligned with the intended setting, for example to change to map2 then speedo=0, tach=2000rpm, you'd press and hold the BC button. The blinkers will flash twice and the in dash menu system will close. When you go back in to the menu system you'll note the map has been updated.
