**********s l BMS JB3 Processsor N54 Engine l Make your E89 Z4 faster!

It seems like a few of you guys are looking to increase power in your Z4 35i just like the 135i and the 335i owners are doing.

**********s would like to present the Burger Motorsports JB3 Processor for your N54-equipped Z4!


The factory 135i, 335i, 535i, and Z4 35i ECU comes detuned from the factory and the full potential of the N54 twin turbo engine is inaccessible. Enter the BMS JB3 processor!

The JB3 is the latest generation of the Juice Box Performance Tuners from Burger Motorsports. The new version features completely new microcontroller based hardware, added input/output channels, and integrated safety features. The new version also includes crank position for full 4D engine mapping, air intake temp readings for on-the-fly thermal loading adjustments, direct solenoid boost control to eliminate boost spikes, and the throttle input from the factory ECU to ensure stock-like drivability.

The JB3 units provide safe, reliable increase in horsepower and torque while remaining undetectable to the untrained eyes. Also, it is uninstalled very easily without a trace that it was there!


  • Gain over 80 whp and 80 wtq on pump gas. 180 whp and 155 wtq with race gas and bolt-ons
  • Switch between 10 maps for every occasion, 15 maps with a modified JB3
  • Change maps from the driver's seat
  • Adapts to modifications to support more power (downpipes, intercoolers, intakes, 100+ octane fuel, and more)
  • Invisible to BMW tuning detection software
  • Installs within 30 minutes
  • #1 software choice for the world's fastest 1 Series and 3 Series


  • 2008+ 135i
  • 2007+ 335i / xi
  • 2009+ Z4 35i
  • 2008+ 535i
  • 2008+ X6

Please PM me or call me if you need more information on this tuning device for your Z4! Eddie (714) 583-3330 x 8004 or edward************.com
