Ready to take your BMW twin turbo to the next level?
Burger and VAC ask you: How does 80hp to the wheels (100hp crank) on a completely stock car or up
to 180hp to the wheels (215hp crank) on a fully modified car sound!?
For the advanced user, the JB4 offers flexibility and performance at the most affordable price: A plug and play installation into the ECU harness and powerful built in software offers
excellent gains with very little effort or cost.
Built in deletion of hidden "tuner
detection" codes and compatible with all ECU versions makes this a safe bet
when spending your hard earned cash and with over 5000 in use and
tens of millions of customer miles driven the BMW Juice Box has proven time and time
again to be the most flexible and powerful way to extract the true potential from your
N54 twin turbo!
Now shipping JB4 G5: 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 a BMS USB cable.
This latest version also supports dual-tuning with ECU flash and JB4 piggyback.
Along with a Burger ECU flash and a ungraded turbocharger
package, up to 250hp to the wheels (312hp crank) on a fully modified car is
possible with drivability and reliability.
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 cars 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 penalties.
