Burger Motorsports JB4 Port Injection Controller for BMW — Overview

This is the JB4 add-on controller Burger Motorsports uses to run supplemental port injection on BMW F and G chassis builds. It is not a flash tune by itself - it is the control piece for extra fueling when direct injection starts running out of room on higher power setups. On an F36, this makes sense for bigger turbo, ethanol-heavy, or full E85 builds where the factory DI system becomes the bottleneck.

Pick this over pieced-together standalone port injection control if you already run JB4 and want everything integrated in one ecosystem. It is the more sensible route when your stock high-pressure system cannot keep up, but it also means the car needs the rest of the port injection hardware and tuning to match. This is not a bolt-on for a lightly modified street car, and it is overkill if your current setup is still within the limits of the factory fuel system.
