Port Fuel Injection Controller for BMW Turbo Six Engines by Burger Motorsports

Unlock stable, precise fuelling on N54, N55 and S55 builds with Burger Motorsports' dedicated auxiliary injector driver. This compact plug-in module lets your existing JB4 piggyback manage a separate port fuel rail with exceptional accuracy, delivering smoother throttle response, clean power under boost and extra protection when you push for higher horsepower. Ideal for tuned street cars and track setups seeking consistent AFR control with minimal hassle.

What makes this auxiliary fuelling module the go-to choice

  • Direct integration with your JB4 tuning system for complete port fuel oversight
  • Adjusts added fuel by boost level, gear, engine speed and injection pressure for OEM-like drivability
  • Tip-in enrichment for crisp response as you come onto throttle
  • Failsafe logic monitors injector flow and flags a fault if an injector is unplugged or shorted
  • True plug-in harness, no standalone maps or programming on the controller required
  • Clean, reliable alternative to older AIC6 style controllers

If you are adding a secondary injector rail to support bigger turbos or ethanol mixes, this BMS unit gives your JB4 the brains to run auxiliary injectors properly. The result is confident high-load fuelling, excellent cruising manners and the reassurance of built-in safety checks.

Who is it for

Enthusiasts running BMW N54, N55 or S55 engines who want a tidy, proven way to manage port fuel on a JB4-tuned car. Perfect for hybrids, upgraded HPFP or LPFP setups, E blends and anyone targeting reliable, repeatable power without a clumsy standalone controller.

Compatibility

Engine families: N54, N55, S55. Designed for turbocharged straight-six BMW applications using a JB4 piggyback.

Important: a JB4 is required for operation. This module does not function on its own.
