WORX × HP Tuners remote tuning
Tune it from
your phone.
Your ECU stays in the ski. Switch tunes or go back to stock whenever you like.
Three parts. One bundle.
Every remote tuning bundle includes all three.
The device
Plugs into your ski and talks to your phone. Works on every ski you own.
The cable
Connects the device to your ski. Sea-Doo bundles include the Sea-Doo cable. Yamahas need two cables, one for flashing tunes and one for diagnostics, and Yamaha bundles include both.
The licence
Locked to your ski's VIN, the hull ID number on the back of your ski. Unlocks your WORX tunes and keeps your stock tune safe.

Sea-Doo Remote Tuning Bundle
$1,399.00
MG1 Remote Tuning Bundle
$1,899.00
The year won't tell you. Plenty of 2024 and 2025 Sparks still run the older ME17. Pop off the small access hatch on the side of the hull and you'll see the ECU sitting on top of the airbox.

It matters because each ECU needs a different product and price. The ME17 is quicker and cheaper to tune. Not sure? Send us a photo or your VIN and we'll check for you.

Sea-Doo with a locked MG1 ECU? MG1 ECUs (silver metal case, 2024 onwards 325s and some Sparks) come locked from the factory, so choose the Sea-Doo MG1 licence + unlock.

Common questions
What do I get in a bundle?
The WORX x HP Tuners remote tuning device, the cable for your brand of ski (Yamaha bundles include both the flashing and diagnostics cables), and one tuning licence for your ski. That's everything you need to tune it.
Can I go back to stock?
Yes, free, any time. Your stock tune stays in the app, so you can write it back yourself in a few minutes.
I have more than one ski. What do I need?
One bundle for your first ski, then a tuning licence for each extra ski. The same device works across all of them, and the same cables work on every ski of the same brand.
How long does it take?
Once you've read your ECU with the app, we load your WORX tunes, usually within one business day. Writing a tune takes a few minutes. MG1 ECUs (2024 onwards Sea-Doo 325 models and MG1 Sparks) need a one-time unlock first, about 2 to 3 weeks.
Does my Spark have the ME17 or MG1 ECU?
Don't go by the year. Plenty of 2024 and 2025 Sparks still run the older ME17. Pop off the small access hatch on the side of the hull and look at the ECU on top of the airbox: black plastic means ME17, a silver metal case means MG1.
The ME17 is quicker and cheaper to tune. Watch the quick video on how to check, or send us a photo and we'll tell you.
I'm outside Australia. Which should I choose?
Remote tuning. We do accept ECUs from overseas, but international postage costs more and there's always a risk of it going missing. With remote tuning, your ECU never leaves your ski, and we ship bundles worldwide.
Will a tune make my ski less reliable?
Not the way we do it. There's no magic setting that adds huge power and stays as safe as stock, so we don't chase one. We balance the rev limit, ignition timing and fuel to suit your setup, and set it up to run 150 to 200rpm under the limiter. Fuel matters too. All WORX tunes need fresh 98 octane.
