so if you leave it on map 0 it wont be any less reliable than on stock tuning? i want the jb4 but only want the performance increase during certain times.
A little bit ambiguous… How can I save setting if I wanna 5/7 which is sweeps guages? You said pressing left minus botton to make speedo to 0 and press again to save, but this moment 0/7 will be saved which is MAP 7 function.How can I save 5/7 setting directly?
How much does jb4 cost?
This is cool as fuck.
What about a map for valet parking? 🙂 Like speed or rpm limit for when valets are using.
my 135i doesnt marks exactly on the 1, 2 , 3 numbers, it does in the middle and between of them..whats happens?
I'd like to know why my gas gauge move after select the map 2?
Thinking about getting jb4 just a little worried about installing it and messing something up anyone have a good video so I can put into my 335i or should i have some do it for me?
Does the JB4 affect reliability? Basically, does it harm the powertrain at all? And does it affect my warranty?
What is a map
Is tuning required on a rolling road and can a tuner modify a map?
which car has better info screens under $50k ?
S4 ? Vette ? Cayman ?
no you need a juice box installed on it
can you do this on every 335?
Do not use 86 octane on your car, for the love of god. If anything put it in stock mode and baby it around.

thanks very helpful : )
what is the maximum rpm limit you can make ?
