The new BMS JB4 gives you up to 80HP to the wheels on a completely stock car and up to 250HP to the wheels on a fully modified car
Are you ready to take your turboed BMW to the next level in tuner performance? Burger Motorsports has finally released the all new JB4 PNP Stage 3, and yes it is everything you can imagine and much, much more! The new BMS JB4 gives you up to 80HP to the wheels on a completely stock car and up to 250HP to the wheels 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 4500 in use and tens of millions of customer miles driven the JB3 has proven time and time again to be the safest and easiest way to extract the true potential from your N54 twin turbo! However the new JB4 will blow the old JB3 out of the water in everyway with its endless features, this is truly to hottest product to hit the tuner industry!
What makes the JB4 Stage 2 better then the Stage 1 JB3? The upgrade to the stage 2 JB4 is very similar for the upgrade in the Stage 2 N54 JB4 tuner. Coming with several new features such as hand controls on the steering wheel, more power and tuning characteristics and more!
The JB4 features a simple plug and play installation harness and built in deletion of hidden ""tuner detection"" codes; compatible with all ECU versions. The N54 JB4 features 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 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.
Just installed the jb4 onto my 2011 335is. I was a bit skeptical at first since BMW already had a tune on the 2011 335is. After installing it, I didn't seem to notice a difference, until after the 2nd or 3rd pull, I can feel the actual pull of it, but also a smoother one than the jb3. overall, ecstatic to drive it more tomorrow, did not regret the install, and furthermore, was worth every penny!!!
