Frequently Asked Questions

Will this work on my 2017+ Touring with Milwaukee-Eight?

No — this tuner is specific to 2008-2016 Touring models with 73-pin ECM. Milwaukee-Eight models use a different ECM connector.

Is this street legal in my state?

This tuner is not legal on pollution-controlled vehicles in California. Check your state and local emissions regulations before installing.

Can I adjust both fuel and spark at the same time?

Yes. Use the pushbuttons to select and modify fuel trim and spark retard independently across different RPM and throttle position ranges.

Do I need to tune my bike after installation?

The Twin Tuner II plugs into the OEM 73-pin connector and requires custom mapping to your engine setup — professional dyno tuning is recommended for optimal results.
