| - | The ignition module is an Ultima Single-Fire version, feeding separate trigger signals to the dual coils to fire the front & rear spark plugs separately. It fits in the nosecone where previously only the cam sensor plate mounted. A dual-fire version of the Ultima ignition could be used instead, with the appropriate dual-fire coil. Using the VOES connection (which helps with idle & cruising spark timing by providing more advance) is recommended, but implementing a tachometer is optional. | + | The ignition module is an Ultima version and fits in the nosecone where previously only the cam sensor plate was mounted. In this diagram the __Ultima Single-Fire Configuration__ is used, feeding separate trigger signals to the dual coils to fire the front & rear spark plugs separately (the Ultima BLUE wire fires the front coil & the Ultima PINK wire fires the rear coil). |
| + | |||
| + | If you choose to use a __dual-fire configuration of the Ultima ignition__, it will also work when you pair it to the appropriate dual-fire coil. In that case, you will only use the Ultima PINK wire to fire the selected dual-fire coil. (The Ultima BLUE wire will not be used at all with a dual-fire version.) | ||

| + | Using the VOES connection with either configuration (which helps with idle & cruising spark timing by providing more advance) is recommended by connecting the Ultima VIOLET wire to the VOES unit. | ||
| + | |||
| + | Implementing a tachometer is optional. If used, the Ultima GREEN wire will connect to the tachometer signal input wire. The tach will also need a ground connection on the bike and key-operated power for the tach light. | ||
| There are only six wire colors to minimize wire purchase: **Black - White - Red - Blue - Yellow - Green.** There are enough colors so that no connecting point should have the same color twice in order to make it easier to know which device is connected to/from another device. | There are only six wire colors to minimize wire purchase: **Black - White - Red - Blue - Yellow - Green.** There are enough colors so that no connecting point should have the same color twice in order to make it easier to know which device is connected to/from another device. | ||
