Seadoo ECU Reflash Service

Whether you've just bought your Sea-Doo or you've been riding it for years, a WORX tune is one of the easiest upgrades you can make. Take your ECU out, post it to us, and we'll tune it and send it back, usually within 1 to 2 business days of it arriving.

As standard, we recommend an 8400rpm limit tune for Sea-Doos. We can also convert 90hp GTI models to 110hp. Want a different tune? Write it on your reflash form when you send your ECU.

For the best results, pair your tune with a lower pitch impeller. It lets the ski rev higher and closer to its sweet spot.

Benefits:

• Boost limit removed
• Advanced ignition timing for stronger low and mid range acceleration
• New fuel and ignition tables for the top of the rev range
• No internal engine changes needed

Fits:

• Sea-Doos with the ME17 ECU: 2010 to 2023 models, plus 2024 onwards 230 and 300 supercharged models like the GTX 300 and GTR 230
• Sparks have their own Spark reflash
• 2024 onwards 325 models run the MG1 ECU and aren't available by mail-in yet. See remote tuning instead
• 2024 onwards 130 and 170 models also run the MG1 ECU and we're still building tunes for them, so email us first

All WORX tunes need 98 octane fuel.
