BMS F Chassis N55 BMW JB4 F10 A Tuner 2012-2013

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, 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 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!
