Dynojet Power Vision 4 and Target Tune
Understand what the phone-based flash tuner does and where wideband hardware fits.
Power Vision 4
Power Vision 4 connects to a supported motorcycle and uses Dynojet’s phone app to flash a calibration to the factory ECU. Dynojet documents vehicle licensing and data logging in its user guide. The exact tunes, diagnostic connection, and features depend on the application.
For log review, keep the bike and calibration version alongside the exported file. If you’re shopping for a tuner, confirm that your exact ECU and model year are listed and that the logging or calibration features you need are available for that application.
Target Tune
Target Tune is separate hardware for supported Harley-Davidson applications. It uses wideband oxygen sensors with a Target Tune-enabled calibration so the ECU can run wideband closed-loop fuel control. The presence of Power Vision support does not establish Target Tune fitment by itself.
Check the installation guide for the specific kit. Confirm the calibration requirements, sensor and harness fit, and whether the exhaust has the correct sensor mounting provisions.
Good questions to ask at the bench
- Which bike, ECU, and Power Vision part number are you using?
- Which calibration and firmware versions are installed?
- Do your logs use the stock sensors or a separate wideband system?
