How about up to 60hp to
the wheels (80hp crank) on a completely stock car or up to 100hp to the
wheels (120hp crank) on a fully modified car? The JB4 features a simple
plug and play installation harness and built in deletion of hidden
"tuner detection" codes. Compatible with all ECU versions. With
over 10,000 in use and tens of millions of customer miles driven the JB
has proven time and time again to be the safest and easiest way to
extract the true potential from your BMW turbo!
Now shipping with JB4 featuring 5x the processing
power, 2x the memory, more robust signal conditioning, and integrated
CANbus. Our new CANbus module allows the JB4 to communicate with your
vehicle like never before. New features include code reading/deleting,
optional in dash boost, timing, air/fuel, shift light, and IAT gauges,
autotuning, a buttery smooth new CANbus based integrated boost control
system, map switching on the fly via steering wheel controls, built in
downpipe fix, hot/cold oil temperature protection, progressive methanol
integration, water pump remapping, gear dependent boost control/traction
assist, and much more to come with free firmware updates uploaded using
a windows laptop (or mac w/ windows emulator) and BMS USB cable.
In addition to our performance mapping the JB4
features several "on the fly" user selectable maps including a 100%
stock bypass map, a 4500rpm rev limited valet mode, a fuel economy map, a
progressive methanol map, a race gas map, and for those interested an
rpm by rpm user adjustable map. And unlike other flash and piggyback
tunes that charge per the map and lock to your VIN the JB4 is 100%
unlocked. Meaning you get access to every new feature we release free of
charge and when your lease is up will be able to resell the JB4 without
penalty.
Remember the JB4 does not require any additional
modifications or previous stages. Simply install the JB4 as your first
and only modification and enjoy an entirely new fast and smooth driving
experience. The JB4 also does not require any user setup or
customization. Those features are included for more advanced users but
for the average enthusiast simply install and enjoy!
Due to DME compatibility
issues we do not offer and have no plans to develop an N55 Stage2 tune
for the 535, X3, X5, or X6. The most powerful tune you can use for these
models
is our N55 Stage1 |
