POWERSHOT FUEL

The new R&D Powershot Fuel
Injection/Engine Tuning module for the YAMAHA SHO/FZR will deliver
increased acceleration, stronger mid-range, and increased top speed
performance by delivering a higher performing air to fuel ratio (A.F.R.)
and allowing higher mass air/boost pressure levels to be utilized. R&D
Performance has data logged and analyzed the O.E.M. fuel map and Fly
By Wire functions on the new YAMAHA SHO/ FZR four stroke engine and
has determined that one of the main horsepower and performance
holdbacks in Yamaha’s Fly by Wire E.C.U. system is the mass air or boost
limitation that is controlled by the Fly by Wire Throttle System. The Yamaha
E.C.U. manipulates and controls the mass air or boost pressure levels by
closing the throttle plate which limits peak horsepower performance. The
R&D Powershot interfaces with the E.C.U., fuel injectors, and sensors to
unlock, take over, and control mass air or boost limitations. The R&D
Powershot will allow the R&D C1 and C3 Monster Supercharger Wheels
to perform to their full potential by defending against unwanted codes and
internal E.C.U. limitations. The R&D Powershot comes pre-programmed
and coded to safely alter the fuel map, intercept and recondition sensor
voltage signals allowing up to 10 P.S.I. of boost pressure without throttle
limitation or regulation. The R&D Powershot allows custom fuel tuning to
cruise, acceleration, and top end zones. Top end fuel mixtures can be
custom tuned from 13.5:1 (lean) to 11.5:1 (rich) on the fly. Quicker accelera-
tion, stronger mid-range, and increased top speed performance is the result
when the A.F.R. is tuned for optimum performance. The R&D Powershot is
fully adjustable to accommodate and properly performance tune the A.F.R.
for any combination of aftermarket parts.
No more Boost Limiter!

RIVA LC1 WIDEBAND LAMBDA CONTROLLER
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 temperature, alti-
tude and sensor condition.
Key Benefits Include:
* Fully digital wideband controller.
* Auto calibration capability to compensate for changes in temperature, alti-
tude, and sensor condition.
* Plugs directly into RIVA/ViPEC ECU harness.
* Includes Bosch LSU 4.2 02 sensor.

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. 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.
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.

ECU REPROGRAMMING
SERVICES
R&D is now offering Yamaha FZR and SHO ECU
reprogramming services. The R&D team have been testing and developing
ECU programs to allow a range of performance levels to be reached for the
recreational enthusiasts who are not interested in a full standalone aftermarket
ECU. Entry-level programs will provide the enjoyment of a raised RPM limit
setting as well as the internal boost limiter being either removed or raised.
Ignition timing will be altered to safe performance levels that will allow the use
of 91 octane pump gasoline. There will be several initial performance levels to
chose from that will work with stock or R&D C1 & C3 Monster Wheels.
Programs offered will be recreational performance tuned to safe AFR values,
and can be further custom tuned with the R&D Powershot (Richened) to
accommodate additional boost levels. With the purchase of the R&D ECU
Reprogramming Service, customers who have previously purchased an R&D
Powershot Fuel Control Unit can send it in along with their ECU to R&D for
free re-programming, to allow custom fuel tuning to work with the new ECU
Programs. For best results, we recommend upgrading and using the
Powershot for custom fuel fine-tuning. Fuel tuning or AFR conditions should
always be checked and verified, as values can be slightly different from one
craft to another. R&D strongly suggests that AFR tuning be periodically verified
using an Innovate LM1 or LC1 logging kit also available from R&D.
