The Daytona Twin Tec is the perfect solution for the rider that doesn't want to mess with settings and adjustments. The DTT simultaneously auto-tunes the fuel curves for both front and rear cylinders under actual riding conditions with new WEGO IIID dual-channel wideband oxygen sensor interface. It is a fully programmable plug-in replacement for the stock Delphi� controller and basically replaces the entire PCM system. Utilizing a robust alpha-N (throttle position and rpm-based) fuel control eliminates problems with long duration/high overlap camshafts which makes this a great choice for those with heavily modified motorcycles.
