Maptuner ECU Tuning & Diagnostics

Maptuner ECU tuning, diagnostics and service equipment for personal watercraft. Browse Maptuner Nano and MaptunerX hardware, vehicle licences, complete tuning bundles, programming cables and diagnostic accessories for supported Sea-Doo, Yamaha and Kawasaki models.
South Quay Leisure provides UK-based product matching and practical support. Tell us your make, model, year, engine output and intended setup and we will help match the correct handset, cable and licence.
Choosing the right setup
  • Maptuner Nano: compact Bluetooth hardware controlled through a compatible phone or tablet.
  • MaptunerX: standalone colour touchscreen hardware.
  • Licence: normally required once per tuned vehicle. RIVA and Maptun licences use separate calibration libraries and their prices, maps and specifications vary.
  • Cables: depend on manufacturer, engine family and model year; some BRP Nano applications connect directly without a separate programming cable.
European Sea-Doo 300 hp note: European-market 300 hp models are not factory speed restricted, so US-market speed-override claims do not apply. Ask us to verify your exact application before purchase.
Products marked ORDER-IN PRODUCT are specially sourced and may have a longer lead time. Digital licences are vehicle-specific and normally non-refundable after activation.
Performance calibrations are intended for competition/off-road use where applicable. Manufacturer names are used only to identify compatibility. South Quay Leisure is independent and is not endorsed by or affiliated with BRP, Sea-Doo, Yamaha or Kawasaki.
