Ready to take your BMW twin turbo to the next level?
How about up to 60hp to the wheels (80hp crank) on a completely stock car, or up to 100hp to the wheels (120hp crank) along with breathing mods!
For the advanced user, the team at VAC feels that the JB4 offers the most flexibility and performance of any performance tuning currently available for the N55 twin-turbo platform: A simple plug and play installation 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!
That latest and greatest Version 4 (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, auto-tuning, 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.
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 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.
-The JB4 does not require any additional or previous modifications to gain power. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth driving experience... or add to bolt-on's like downpipes, intercooler, cat-backs, larger turbos, intakes and more!
-Each JB4 requires no user setup or customization to operate. Those features are included and work right after installation. This is a product for more advanced users or for the average enthusiast simply install and enjoy!
Fully compatible with DCT, Auto and Manual transmissions!
