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.
