Reflashing gets mentioned a lot in tuning discussions, but many owners are not entirely sure what actually happens to their Sea-Doo's ECU during the process.
What Reflashing Actually Does
The ECU's stored map, which controls fuel delivery, ignition timing and boost targets, is replaced with a new one, changing how the engine behaves without any physical part being swapped.
Doing It Yourself
The M-JET Flasher connects to your Sea-Doo and lets you reflash the ECU directly through the app, without needing a dealer visit.
