Terry did get back to our platform and updated the firmware so you can have map 6 again Plus nearly all of the gauges now work. There are five different firmwares listed that will work with the E70/N63, The best of the bunch is by far the JB4_P62_X5N63_1_T3.hex so make sure you have that loaded.

I also recommend you contact ESS tuning and grab their tune. I am running their stage 2 + map3 (still playing with map6) for around 18-20psi boost. My near 10 year old 170k+ mile X5 is busting out sub 4 second 0-60 times, on par with a X5M. People can Say what they want about the N63, when its tuned its awesome and makes your X5 an amazing sleeper. Little clip below of just messing around with map3.
