G5 Upgrade Board for the N54 JB4!
Upgrades your JB3 or JB4 G4 control box to the latest JB4 G5 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.
New with the G5 board we've added an optional isolated boost control system, flat foot / no lift shifting for manual transmission cars, a 2STEP rev limiter, speed limit defeat built in, integrated crank position offset built in, and extra expansion input/output.
