BMS JB4 Port Injection controller ala cart BMW *Each manifold is CNC machined

*Each manifold is CNC machined after being cast to remove any excess material and weight involved in the casting process

but will add a short lead time and processing fee to the order for custom colors

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

Inlets and outlet are placed in the same location as the OEM cooler so you can retain your factory charge pipes

BMS JB4 Port Injection controller ala cart BMW *Each manifold is CNC machinedThe 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
