Heads up. JB4 for N63 now available.
Busy happenings over at the N54tech board. Terry has finally produced a Stage 2 JB4 for N63 (not TU) with CANBUS interface which finally gives steering wheel map selection and other selectable features. If you have run a JB4 before (I did on my N54 335i) you will know what I'm talking about.
If you have a current Stg 2 box, the upgrade is FREE!!
If you plan to run higher octanes, there is an optional wastegate control module. Not sure of the cost - under $200 I think.
Getting mine this week!!!!
Not affiliated etc.
