BMS BMW N54 JB4 Port Injection Control Module
JB4 Port Injection Control Module
The JB4 Port Injection Control Module allows the JB4 full bidirectional control over the port injection mapping. The JB4 controls port injection flow as a function of boost, gear, engine speed, injection pressure, and includes advanced features such as tip in enrichment and fuel injector flow detection to trigger a safety in the event of an unplugged or shorted fuel injector. Unlike the old AIC6 controller no programming or mapping is required on the controller itself. You simply connect it to the JB4 harness using the included PNP connectors. Note the fuel controller requires a JB4.
