Burger Motorsports JB4 Tuner - BMW N54

Burger Motorsports built the JB4 to take the E chassis N54 from mild to wild with a single plug-and-play installation harness, compatible with all ECU versions and transmission types. On top of several driver-selectable performance maps, it includes a 100% stock bypass map, a valet mode, E85 support, progressive water/methanol injection support, a racing fuel map, and an auto-tuning map that continuously adjusts to your climate, octane, and current modifications.Other features include optional in-dash gauges, a programmable shift light, on-the-fly adjustable torque limiting for the track, an optional 2-step rev limiter and no-lift-shift for manual cars, and an optional speed delimiter. The JB4 doesn't require any prior modifications or stages; install it as your first and only upgrade and grow from there.Important Compatibility InformationThis JB4 connects to your phone or tablet via the optional JB4 Bluetooth Wireless Connect Kit, which uses a separate power wire, or to a Windows laptop via the BMS Data Cable. This N54 unit is not compatible with the newer JB4PRO Bluetooth adapter used on Burger Motorsports' current-generation tuners.Features
