Two Brothers Racing Honda TRX450R Dyna FS Ignition - Manual (Page 2)

This ignition allows the engine to rev to a higher RPM than what it has before. At these high RPMs, the performance
limits of other engine parts(exhausts or valve train for example) may be found. It may be necessary to replace these
parts for best engine performance. Consult with an engine builder for what works best for your engine and
application.
Programming
Programmable versions require a separately purchased programming kit to reprogram them. If the programmable
ignition was not purchased directly from Dynatek, the dealer may have programmed a custom set of ignition curves.
The dealer should be consulted with any questions regarding the curves that are programmed into the ignition. On
the 2006 models, to program the ignition, you will need to unplug the adapter from the ignition, and plug the
programming cable into the ignition.
The TRX450R Dyna ignition comes with 2 extra wires: a green wire, and a blue wire. These are unused with the
stock ignition. The blue wire can be set up to function as a switch that turns on and off at certain RPMs to control
additional electronics, such as powerjets or nitrous systems. It is rated at 2Amps max output. For anything more than
that, use a relay. See the attached digram for how to wire a relay. The use of these is covered in the instructions for
the programming kit. The green wire is a tach output that produces a 12V square wave 2 pulse per engine revolution
tach signal that is compatible with most 4 cylinder auto/motorcycle tachs. See the attached wiring diagrams.
Troubleshooting
Troubleshooting the Dyna ignition is simple. If the bike will not start or run at all, reinstall the stock ignition. If this
fixes the problem, then the Dyna ignition should be returned to Dynatek for testing. If switching to the stock module
does not fix the problem, then the problem is somewhere else on the bike. Follow the troubleshooting procedures
outlined in your owners manual.
If the bike runs, but poorly, put the stock ignition back on the bike. If this fixes the problem, reinstall the Dyna
ignition. If you are using non stock plug wires, plug cap, ignition coil, spark plug, or stator, replace them with OEM
units. Then follow the procedures in the calibration section to set the Dyna ignition up to work with your bike. If
calibration doesn't fix the problem, the ignition should be returned for testing. If the problem persists when using the
stock ignition then the problem is external to the Dyna ignition. Follow the test procedures outlined in your bike
owners manual to pinpoint the problem.
WARNING:
Installation of a grounded tether kill switch to the ignition coil signal
will damage the CDI and void the warranty.
Magneto-CDI (Banshee/TRX250R/400EX/450R/etc.): Use a normally open tether kill switch
connected in parallel with the stock kill switch input to the ignition. When the tether is removed, it
should ground the input to the ignition.
TRX450R KILL INPUT – BLACK/WHITE at the ignition module. The KEY SWITCH uses this same
circuit.
