MaptunerX-tuning for Yamaha Outboards


A smarter choice: Increase the power of your existing outboard engine instead of buying a new one!

From 10% to 46% increase in power depending on model

Your boat will plane out faster which results in better fuel economy*

Flash the ECU yourself with the Maptuner – no need to remove the ECU or visit a dealer

Only the software of the engine is changed and can easily be restored back to stock

Over 20 years’ experience of engine tuning and optimization

Extended diagnostic features available**

*Fuel economy is improved in almost all known cases, but there can of course be some deviating cases where the fuel consumption stays the same or increases.

**Available diagnostic features depends on engine model. Contact us for more information.

Tuning made easy, fast and reliable!

The engine tuning is developed by us over a long period of time and carefully calibrated using all the knowledge we have acquired from over 20 years of experience in engine tuning and optimization. We have also created our own handheld programming unit – called the Maptuner – which connect to the engine to perform the upgrade. All this work so that you early have to do any work! 

To perform an engine software upgrade (called a ‘flash’) you only need a Maptuner (which you can buy or loan from us), a cable and a tuning license. That’s it! 

When the flash is done you can remove the Maptuner from the engine. If you want to restore the engine to it’s stock software you simply connect the Maptuner again.

Additional features
The tuning license also includes Maptuner Apps to read fault codes and engine history. With an optional diagnostics cable you can access these features. Oil Change History, Service History and RPM History is available depends on the model of outboard.

Other optional apps are Monitoring and Datalogger. With these apps you can further troubleshoot your engine. Purchased separately.
