Burger Motorsports Jb4 -stage 3 - Bmw 335i 335xi 335i Xdrive N54 Engine-with Usb on 2040-parts.com

How about up to 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? 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 5000 in use and tens of millions of customer miles driven the JB Stage3 has proven time and time again to be the safest and easiest way to extract the true potential from your N54 twin turbo!

Now shipping with our latest G5 board 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, optional isolated boost control, 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. For those who have access to E85 (ethanol) fuels the JB4 will automatically tune itself for them yielding huge power gains over pump gas alone. In addition a speed limit defeat, manual transmission 2STEP rev limiter, and manual transmission no lift shifting can be enabled by adding in an extra harness.

USB cable included. 

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!
