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.
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.
