AIC2-6 Six Channel Auxiliary Injector Controller for BMW N54 and N55

Looking for a rock solid way to add port fuel on your twin turbo BMW straight six without upsetting factory driveability? This AIC2-6 unit is a proven auxiliary injector controller that drives six additional injectors with precision. Ideal for N54 and N55 port fuel setups, it delivers the extra fuelling you need under boost while leaving the stock ECU strategy intact. Supplied with an injector loom using USCAR EV6 and EV14 connectors.

We run this controller on our own builds and our customers consistently praise the smooth off‑boost manners, crisp tip‑in and stable air‑fuel ratios at high load. If you are searching for a BMW fuelling upgrade that simply works, this is the dependable solution.

Why enthusiasts choose this controller

  • Boost-referenced auxiliary fuelling only when you need it, keeping OEM-like behaviour in normal driving.
  • Perfect companion for port fuel rails on direct-injected N54 and N55 engines where the factory system reaches its limits.
  • Integrated harness with USCAR plugs to suit EV6 and EV14 injectors for a tidy, straightforward install.
  • Two internal injector drivers with the option to run a single shared or independent fuel tables. Each driver supports up to four high-impedance injectors.
  • Map switching via onboard comparators or user input to suit different fuels or boost targets.
  • Accepts tachometer signals with user-definable pre-scaler and post-scaler so it works with a wide range of RPM sources.
  • Select between one and eight injection events per engine cycle for precise control.

Flexible calibration and live tuning

  • Live tuning and data logging using TunerPro software with more capability than the earlier AIC-1.
  • Easy connection over USB for quick setup and revisions.
  • 2D load versus RPM tables for accurate delivery across the rev range.
  • Compensation tables for barometric pressure, inlet air temperature and injector dead time.
  • Uses MAP or MAF as the load reference for consistent fuelling as boost rises.
