What Is the Sim Flag Indicator JJIF-01

Known worldwide as the "iFlag", the Sim Flag Indicator JJIF-01 is JohnJohn 3D's flag indicator: a dedicated peripheral built to bring more immersion and more information into your driving.

Connected to SimHub, it reads your favorite simulator's telemetry and turns every race event (flags, gear shifts, nearby rivals, car warnings) into clear visual signals, exactly when you need them.

It's the kind of detail that separates a regular setup from a professional one: less time looking at data screens, more time with your eyes on the track.

Available Functions

Every function runs in real time, synced to your simulator's telemetry via SimHub. Availability may vary depending on the SimHub version and the chosen simulator.

Flags

Yellow, black, blue, white and green: each flag appears the instant it happens on track.

Gears + Rev

Built-in gear indicator with shift warning, so you always shift at the right moment.

Spotter

Instantly know if a rival is in your blind spot, on your left, right, or both sides.

Warning LEDs

ABS, traction control, low fuel and other car alerts, straight on the LED matrix.

Custom Animations

Outside of races, create your own animations for the iFlag: the only limit is your creativity.

SimHub: The Brain Behind the iFlag

The Sim Flag Indicator JJIF-01 doesn't work on its own: it needs SimHub installed on your computer to function. SimHub is what reads your simulator's telemetry and sends flag, gear, spotter, LED and animation commands to your iFlag.

SimHub is free for basic use and compatible with dozens of simulators (iRacing, ACC, rFactor 2, F1, and more). Installation is simple: download SimHub, connect the JJIF-01 via USB, and set up the flag and telemetry plugins, no extra cost beyond the product itself.
