Frequently Asked Questions

Do I need to rejet my carburetor with this ignition module?

Timing adjustment alone typically does not require rejetting. Carburetor changes depend on your specific engine modifications and fuel type.

Will this work with my factory security module?

Yes — the Daytona TC88/A supports all OEM sensors including Harley's theft/security modules without modification.

Is installation complicated, or can I do it myself?

Plug-in installation requires no wiring changes. Removing the stock module and fitting the Daytona takes about 15 minutes with basic hand tools.

What's the benefit of the multi-spark mode?

Multi-spark fires multiple ignition cycles during cold start for faster engine turnover, and can smooth out idle quality during casual cruising.

Can I adjust the timing on the bike, or do I need a computer?

The Daytona provides a wide range of timing adjustment — specific adjustment method depends on the module's control interface; check the manual for your setup.
