OBDII Adapter Cable Yamaha Marine (Flashing)

Flash your Yamaha outboard, WaveRunner or jet boat. These cables connect an HP Tuners MPVI3 or MPVI4 directly to the Yamaha ECM so you can write calibrations. Built-in battery clips keep the ECM powered during the write, since the engine has to stay off. Choose the cable that matches your ECM's connector above.

Flashing only. For live data, scanning and diagnostics you need the separate Yamaha 3-Pin diagnostic cable.
