yes, jb1 is a 'signal bender'/'piggy back' tuning box.
I had something very similar on my twin turbo 335i bmw - the JB4.
I had awesome results with it in terms of power/torque increase - totally transformed the car as its only mod.
i dont believe the jb1 on the R is quite as good, but I've read nothing but great reports so far.
one other feature the jb4 has on the bmw is gauge hijacking, (stock fuel gauge becomes a boost gauge on a certain throttle % & many other combinations). As well as dataloging & map selection - all from using the steering wheel buttons.
if the jb4 gets released for the R i will get one otherwise its going to be the JB1.
