01 / About FIC6
About FIC6
F/IC6 works alongside the factory ECU, intercepting 6 injector signals and correcting selected sensor signals. Its ignition table retards timing; it does not advance timing or provide standalone ignition control.
Six intercepted injector channels retain the factory ECU.
Six 21 × 17 maps cover fuel, ignition retard and sensor correction.
Internal 64 KB logging with adjustable sampling.
Two calibrations selected through the user-switch input.

Package contents
The actual supplied contents are confirmed in the itemized quote. Check the following items before payment.
Ask whether the price covers the main loom, USB cable, MAP hose and bypass plug, or the controller alone.
04 / Fitment & installation: AEM FIC6 Controller
Fitment & installation: AEM FIC6 Controller
Check the model, hardware revision and connector pins against the device’s wiring diagram.
Use the exact ECU wiring diagram; verify every circuit for continuity and shorts before connecting power.
Keep the factory ECU connected. Identify parallel signal taps and intercepted circuits, then check crank / cam signal polarity and the input-to-output direction of each injector circuit.
Connect the internal MAP hose to a manifold-pressure port after the throttle body. Check for leaks and keep the hose clear of heat and sharp bends.
05 / Questions about FIC6
Questions about FIC6
Can F/IC6 advance ignition?
No. F/IC ignition tables accept negative correction to retard timing, not advance it.
Is the F/IC6 universal harness plug-and-play?
The universal flying-lead loom requires vehicle-specific wiring. A matching patch harness and bypass plug are separate package checks.
Does FIC6 replace the factory ECU?
FIC6 works with the factory ECU by modifying selected injector and sensor signals. It is a piggyback controller; the original ECU and its required vehicle functions remain part of the installation.
Does the FIC6 MAP reading show boost pressure?
FIC6 uses absolute manifold pressure. Boost gauge pressure is manifold absolute pressure minus local atmospheric pressure; the two readings must not be used interchangeably.
What is needed to connect FIC6 to a computer?
Install the F/IC software and USB driver, power the controller correctly and connect a compatible USB data cable. If connection fails, check device detection in the operating system before troubleshooting the tuning software.
Can F/IC6 record data without a laptop?
Yes. Internal logging has 64 KB of memory and 10–1275 ms intervals. Logging starts when the configured trigger and user-switch conditions are met; download the result through F/IC software.
Why does F/IC6 not start an internal log?
In normal logging mode, all FIC Logger trigger conditions must be met and the user-switch input must be grounded. In dual-calibration mode, the logging trigger input is enabled by default, but the configured logging conditions still apply.
Can F/IC6 switch calibrations while connected to a PC?
Changing the user switch while connected interrupts F/IC communication. Select the A / B calibration first, then connect, edit or upload the matching map.
Why can the factory ECU cancel a F/IC6 fuel change?
In closed loop, the factory ECU can compensate for the change using its own fuel trims. Monitor those trims with an OBD scanner alongside measured lambda, and check how fuel and O2 corrections interact before making further changes.
Does the F/IC6 40 psia specification mean 40 psi boost?
No. psia is absolute pressure, including atmospheric pressure. The 2–40 psia range is about 0.14–2.76 bar absolute; subtract local atmospheric pressure to obtain gauge boost.
Can the F/IC6 and F/IC8 12 V switched outputs be wired for the same load?
No. F/IC6 SW12 high-side output is limited to 6 A; F/IC8 is limited to 1 A. Use each model’s limits and pinout; injector-driver limits are separate.
Can all F/IC6 wires simply be tapped into the original harness?
No. Tap circuits read signals in parallel; intercept circuits require separate input and output connections after cutting the original circuit. Check direction, trigger polarity, continuity and shorts for each circuit.
