Brand new to the N54. I am considering adding the JB4 to slightly increase the fun factor of this car, but have a couple of questions, since, after searching several forums I'm still unclear on some things:
Are the different maps on the JB4 there to allow for further modding?
Does this device actually learn, and update itself?
On a stock 335i, does it allow switching from a stock to a tuned profile?
These questions have probably been answered 100's of times; I'm just having trouble finding clear answers!
