Ready to take your BMW twin turbo to the next level?
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 thousands and thousands in use and tens of millions of customer miles driven the JB tune has proven time and time again to be a great and easy way to extract the true potential from your N54 twin turbo!
Now shipping with JB4 G5 board
featuring 5x the processing power, 2x the memory, more robust signal conditioning, and integrated CANbus. The 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 that can be uploaded using a windows laptop (or mac w/ windows emulator or Windows OS installed via Bootcamp) and BMS USB cable.
In addition to the 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 may lock to your VIN the JB4 is 100% unlocked. Meaning you get access to every new feature that is release free of charge and when your lease is up, you will be able to resell the JB4 without penalty
