Our all new V88R3 Pro-Series ECU provides huge performance gains to the Sea-Doo Supercharged 4-TEC Engine delivering over 50hp to the stock engine. ECU is fully programmable with either RIVA supplied mapping or user defined parameters. Most calibrations require use of RIVA Fuel Pressure Regulator Kit and 91+ octane pump fuel. Plugs directly into factory wiring harness via waterproof connectors.

SKU: RS11890-ECU-DC-1 Categories: ,



Key Benefits Include:
1) Super fast iSeries Processor delivers superior rev limit control and smoother engine operation.
2) Upgraded “First In- First Out” logging function. On board logging now records continuously, overwriting oldest data when the memory is full.
3) Easy loading of supplied calibrations/maps for various performance applications.

Performance Fuel Mapping: Delivers optimal fuel required for your specific level of modification based on boost pressure.
Performance Timing Curves: Special racing curves produce more power throughout the RPM range.
Rev Limiter Increase: Stock rev limit can been increased so engine RPM can be run higher producing more boost pressure and horsepower.
Boost Control: Provides control via electronic solenoid for turbo applications.
4) Retains all BRP iControl functions. Eliminates restrictive GPS speed limiter and enables craft to start in SPORT mode for full power delivery.
5) Ability to customize RIVA calibrations for special applications. Using supplied software, user can adjust parameters such as Fuel, Timing, Rev Limiter & Boost Control.
6) Retains OEM Dash Display, Engine Diagnostic & Engine Safety Functions: All original dash functions are retained.
7) Internal Data Logging functionality.
8) Provides diagnostic information that can be displayed via computer interface.
9) Includes plug & play connector for RIVA Dash/Logger unit (RY11840-LD-MD60).
10) Includes plug & play connector for optional lambda sensor kit for data logging air/fuel ratios & tuning functions.
11) Direct-Connect design eliminates need for auxiliary wiring harness.
12) Individual Cylinder Knock Control function. Identifies which cylinder is detonating by tracking firing order utilizing OEM knock sensor.
13) User selectable dual calibration capacity for optional Dual Map Switch (part# RY11841-DMS-ECU-DC).
14) Expansion Port for additional user definable inputs & outputs.
15) User configurable software.

2015 models require the use of RIVA Safety Switch Upgrade Kit (part# RS11890-SSUK)
RIVA Pro-Series ECU is for competition use only.
