The Twin Tuner II by Controller seems like an okay choice for motorcycle enthusiasts looking to tune their fuel injection and ignition for some extra performance, but the average 3-star rating makes me hesitant to fully recommend it.

the twin tuner 2 is a great tuner that makes dialing in your bike’s fueling and ignition simple yet incredibly precise and provides crisp throttle response and ample power gains after dialing in the ideal air fuel ratio with its ability to easily adjust fueling across the rpm range shipping was fast and customer service helpful

The Twin Tuner II is a powerful tuning device that allows easy and precise adjustment of fuel delivery and spark timing to match the needs of aftermarket parts, the LED display and optional PC software provide precision tuning capabilities across the entire powerband which is great but I would have liked a more detailed software manual.
