Other features include optional in dash gauges for boost and other engine parameters, a programmable shift light, on the fly adjustable torque limiting to aid with launches at the track, an optional 2STEP rev limiter & no lift shifting for manual transmission cars, an optional speed delimiter, and much more.

As you decide to modify your car further the JB4 is setup to grow with your vehicle. Whether you’re racing a 100% OEM car on pump gas or a 700whp single turbo drag queen, the JB4 has the perfect mix of performance, features, flexibility, and support to ensure your car performs to the best of its potential!
Optional: Genuine Burger Motorsports Data Cable
This proprietary Data cable connects the JB control box to your laptop for use with Burger Motorsports datalogging, tuning, and map loading software. Cable may be left in engine bay and routed in the window or door when needed for a simple install. Alternatively it may also be routed behind the ECU in to the glove box for a clean install and on the fly access.
Please do not attempt to use a standard RS232/USB cable with the JB as it will not work and may damage the processor. All JB software is posted on n54tech.com.
