JB4 Port Injection Control Module for BMW N54 N55 S55 - PICM

The JB4 Port Injection Control Module (PICM) adds precise, bidirectional port injection control to your N54, N55 or S55 - whether you're running stage 1, stage 2, fast road, track day or decat. No standalone tuning. No extra mapping fees. Just plug-and-play integration with your existing JB4.

• Works natively with all JB4 firmware versions - no reflash, no setup, no guesswork
• Controls fuel delivery by boost, RPM, gear and rail pressure - critical for high-boost S55 or twin-turbo N54 builds
• Includes tip-in enrichment for sharper throttle response and injector fault detection for safety
• Fits E82/E90/E92/E93 F80/F82/F83 G80/G82 chassis - confirmed on N54 (E9x), N55 (F30/F80), S55 (F8X/G8X)
• Connects directly to your JB4 harness using included OEM-style connectors - no splicing, no soldering
