RIVA/Vi-PEC V88R3 Pro-Series Yamaha ECU

Our all new V88R3 Pro-Series ECU provides huge performance gains to the Yamaha SVHO, SHO & HO Engines. 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.
FOR COMPETITION USE ONLY. PRODUCT NOT FOR USE ON POLLUTION CONTROLLED VEHICLES.

Super fast iSeries Processor delivers superior rev limit control and smoother engine operation. Upgraded "First In- First Out" logging function. Onboard logging now records continuously, overwriting oldest data when the memory is full. Our V88R3 Pro-Series ECU provides a huge performance advantage to the Yamaha 1.8L Engine delivering over 50hp to the stock supercharged 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.

Key Benefits Include:
1) 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.

2) Ability to customize RIVA calibrations for special applications. Using supplied software, user can adjust parameters such as Fuel, Timing, Rev Limiter & Boost Control.
3) Retains OEM Dash Display, Engine Diagnostic & Engine Safety Functions:

• All original dash functions are retained.
• Provides diagnostic information that can be displayed via computer interface.

4) Internal Data Logging functionality.
5) Provides diagnostic information that can be displayed via computer interface.
