Product Description

Upgrades your current Stage1 control box to the latest N55 JB4 processor. Featuring 5x the processing power, 2x the memory, more robust signal conditioning, and of course integrated CAN. The CAN module allows the JB4 to communicate with your vehicle like never before. New features are too numerous to fully list but include code reading/deleting, optional in dash boost, timing, air/fuel, shift light, and IAT gauges, autotuning, a buttery smooth new CAN based integrated boost control system, steering wheel controls, built in downpipe fix, hot/cold oil temperature protection, progressive methanol integration, water pump remapping, and much more to come with simple firmware updates. Includes required wires that you must add to your Stage1 harness to allow N55 JB4 to work. Fully released for all 135 and 335 E90 models. For RHD vehicles (UK, AU, HK, SG, SA, etc) you will also need the right hand drive extension harness available on the N55 Stage2 order page. For F10/F30 models not all features are available. There is no Stage2 upgrade currently for X3, X5, or X6 models.
