Two Brothers Racing Yamaha YFZ450X EFI Dyna FS Ignition - Manual

DynaFS – Fuel & Spark with RevExtend
P/N DFS7-31 FOR 2009+ YAMAHA YFZ450R EFI
12,000 RPM LIMIT (10,700 stock YFZ450R)
CAUTION: This ignition will increase the engine rev-limiter!
Congratulations on your purchase of a Dynatek product. Please take a moment to read these instructions completely
before installing the module. The installation will only take about thirty minutes, but proper setup for your specific
vehicle may take longer. The DynaFS was designed to work best with the Dynatek coil kit DCK7-9(2009+ models) or
stock coil with the stock coil wire, plug cap, and spark plug. Always use the stock resistor style spark plug cap and a
resistor spark plug.
Description
The DynaFS Module for the Yamaha YFZ450Refi is a piggyback add-on device that will increase the performance of
the stock ignition and fuel injection system. This Module is designed to work in conjunction with the stock ECU, and
will take complete control of the Ignition Timing while safely extending the fuel injection rev-limit. With the optional
Dynatek CurveMaker software or the Dynatek DRSP-1 remote serial programmer, the ignition curves, fuel maps, rev-
limits, and vehicle speed limits can be custom tailored for any application.
Installation
This kit includes: DynaFS ignition, electrical wiring, velcro, cable tie-wraps and instruction sheet. This is a complete
kit, and includes everything needed to install the ignition. Route all wires carefully. Secure wires using the supplied
cable-ties to ensure electrical wires do not chafe or touch anything sharp or hot.
1. Turn ignition key off. Remove the seat, fuel tank cover, and right & left side plastics. Use the supplied velcro
to install the ignition in the preferred location, top of fuel tank (picture 1).
2. Connect the DFS BLACK GROUND wire under the 8mm bolt at the battery negative (picture 2).
3. Connect the Throttle Position Sensor Intercept, Pickup Intercept and Vehicle Speed Intercept (all located on
the left side of engine) by unplugging the stock connectors and connecting the matching DFS harness
connectors in-line (picture 3).
4. Connect the Fuel Injector Intercept (top of engine) by unplugging the stock connectors and connecting the
matching DFS harness connectors inline (picture 4).
5. Route the Coil Connections Harness towards the coil. Connect the Ignition Coil Intercept (at the ignition coil
terminals) by removing the stock ORANGE wire (coil negative) and connecting it to the DFS ORANGE wire.
Connect the DFS coil negative output ORANGE/BLACK wire to the ignition coil. Connect the DFS +12V
Piggyback BROWN/RED to the stock Red/Black +12v source (picture 5).
6. Finally, tie-wrap the DFS Accessory Wires away from the engine and away from hot or sharp objects.
7. Now is a good time to start the vehicle and check that the vehicle idles properly.
8. Installation is complete! Reinstall body plastics and seat. Double-check your wiring and secure all loose
wires using tie-wraps.
