Twin Tuner II by DAYTONA TWIN TEC LLC — a tuning box designed to finely control the injection and ignition of original Delphi twins. Ideal for roadsters, touring bikes, and vintage machines equipped with performance parts (high compression pistons/cylinders, camshafts, high-flow exhausts, low-restriction air filters), it allows for adjusting the fuel mixture and timing to restore consistent engine behaviour after modifications.

• Fuel adjustments: +30% to -20% fuel depending on RPM/throttle position.
• Ignition: ability to retard ignition by up to 10°.
• User interface: mode buttons and up/down for navigating ranges and displaying values on a daylight-readable LED screen.
• Advanced modes: USB option and PC Link Tuner software for downloadable maps and independent front/rear cylinder adjustments.
• Compatibility with Twin Scan II+: record, ride, then import air/fuel corrections into the software to refine the mapping.
• Installation: easy plug-in without cutting or complex connections. Compact size (approximately 4" x 2" x 1/2").
• Finish: black/black and white — Twin Tuner II model, programmable.

The Twin Tuner II is designed for riders looking to optimise the air/fuel mixture and timing without modifying the original electronics. Check compatibility with your model (e.g. several Harley-Davidson Sportster 1200) before installation.
