Bring your Subaru's data into focus with PulseWidth Classic.

YOUR COCKPIT
Choose animated dashboard styles designed for phones and tablets. Keep important readings in view, switch between live data and your selected cockpit, and review minimum and maximum values in Telemetry Command. Optional music information and supported playback controls work with compatible Android media players.

LIVE DATA AND WIDEBAND LOGGING
Record supported vehicle channels and compatible Innovate LM-2/LC-2 wideband data. Choose AFR or lambda in Settings. Missing or disconnected measurements remain unavailable instead of appearing as fresh data. Adapter and simultaneous-device support depend on your hardware setup.

YOUR LOGS, IN ONE PLACE
Browse local, cloud and PWT recordings with dates, duration, channel counts and previews. Zoom and trace saved logs with linked touch cursors, compare channels, and share a CSV through Android's chooser when you choose.

DIAGNOSTICS AND LEARNING
Read supported trouble codes, inspect available self-test information and review Subaru learning tables. Clear codes through the supported, confirmed workflow after addressing the cause. Active faults can remain or return; clearing a code does not repair the vehicle or make emissions tests complete. Capabilities vary by adapter, ECU and calibration.

MAF AND BOOST ANALYSIS
Use chart-focused workspaces to inspect airflow corrections and boost behavior, keep timestamped observations and review saved analysis with the appropriate vehicle and PWT revision. Recording and analysis do not imply that a particular ECU supports automatic adjustments.

On specifically qualified patched ROMs, opt in to MAF automatic RAM updates with saved session recall, verified write/readback and recovery handling. Bounded supervised turbo-dynamics trials and the stock SSM idle-sweep workflow are available where their checks pass. Automatic boost/wastegate tuning is not offered. These are specialist calibration tools, not a substitute for a qualified tuner or a guarantee of safe engine operation.

YOUR VEHICLE WORKSPACE
Sign in to access your Garage and account-linked tune projects. Keep recordings and project work organized, with in-app help for connections, logs, diagnostics and recovery. Protected operations require the appropriate license and compatibility checks.

Optional Remote Tune shares only the PulseWidth app window and telemetry with an authorized participant after you accept on the device. Voice is a separate option. Visible controls let you stop control or end the session. See the privacy policy for data handling.

PERFORMANCE
Use satellite-based performance tools on a suitable closed course. GPS readiness is shown before timing starts. Results depend on device capability, reception and conditions; this is not certified timing equipment.

WHAT YOU NEED
A supported Subaru HC16 vehicle/calibration, an Android 8.0 or later device with USB host support, and a compatible USB OTG adapter arrangement. OpenPort 2.0 is required for supported ROM operations. KKL support does not provide ROM reading or flashing. A PulseWidth account and internet access are needed for account/cloud features. Hardware and applicable tune licenses are not included.

Verify compatibility for your exact vehicle, calibration and adapter. Do not operate the screen while driving. Follow the app's battery, ignition and recovery instructions. If a flash is interrupted, keep ignition ON and follow Recovery; do not key-cycle until the documented safe state is reached. Use the app only for lawful diagnostics and calibration.
