The Twin Tuner II has all the features of the original Twin Tuner and includes ignition timing control capability. You can retard spark timing up to 10 degrees to eliminate spark knock in engines with increased displacement and high compression pistons/heads. The Twin Tuners also have an advanced mode, where you can use the optional USB interface and PC Link Tuner software to make precise fuel and spark retard adjustments. You can make independent adjustments to the front and rear cylinders. Tuner Log software allows real time display of system operation. Real time engine data is displayed on an instrument panel type layout with a round tach gauge and bar graph type gauges for all other parameters. Status messages are displayed in a separate window. In addition to monitoring fuel corrections, you can check proper RPM signal pickup and operation of the throttle position sensor (TPS). The Twin Tuners work great in combination with Twin Scan tuning aids for precise tuning. All you have to do is temporarily install the Twin Scan with WEGO wide-band exhaust gas oxygen sensor accessory. The system can be used for tuning on a dyno or under actual riding conditions on a closed course or race track. You can then export the air/fuel ratio corrections calculated by the Twin Scan into the PC Link Tuner software.
