YAMAHA FX-SHO/FZ/VXR/VXS • FUEL
RIVA/VIPEC
PRO- SERIES ECU
The Pro-Series ECU provides a huge
performance advantage to the Yamaha
1.8L Supercharged 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.
KKeeyy bbeenneeffiittss iinncclluuddee::
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.
2) 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.
3) Includes input for optional lambda sensor kit (part# RY11540-LC1-6S5) for
data logging air/fuel ratios & tuning functions.
4) Individual Cylinder Knock Control function. Identifies which cylinder is
detonating by tracking firing order utilizing OEM knock sensor.
5) Traction Control function. Can be calibrated to match specific applications.
6) Antilag function (for turbo applications).
NOTE: RIVA Pro-Series ECU is for competition use only.

BOOST CLAMP
The LC-1 is a complete wideband
Lambda controller built into a sealed
cable and wired specifically to connect to the RIVA/ViPEC FX-SHO/FZ Pro-
Series ECU via a waterproof factory connector. O2 sensor installs into stock
exhaust pipe using our precision machined Exhaust A/F Sensor Mount. The
LC-1 is more accurate than conventional designs costing many times as
much, and its self-calibrating circuitry can compensate for changes in temper-
ature, altitude and sensor condition.
