The Twin Tuner II allows you to easily adjust your fuel injection and ignition to match the requirements of performance parts including high compression pistons/heads, camshafts, free flowing exhausts, and low restriction air filters. You can add or subtract fuel (up to +30% or down to -20%) and retard spark timing up to 10 degrees.
The user interface consists of up/down pushbuttons and a bright daylight readable LED display to select and change the fuel trim and spark retard in the RPM and throttle position ranges required by most applications. The Twin Tuner II also has 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.
The Twin Tuner works great in combination with the Daytona Sensors Twin Scan II Plus tuning aid (more details below). You don’t need a dyno for precise tuning. All you have to do is install the Twin Scan with WEGO and ride the bike around on a closed course or race track. The Twin Scan software will do the rest
Installation takes only 10-15 minutes. The install does not require splicing or cutting wires. Installation requires you to remove pins at the Delphi® ECM. The pictures below show a typical installation for a 36 pin Delphi® ECM. Installation on 2008-2013 touring models with 73 pin Delphi® ECM is similar, but different connectors are used. Refer to the instruction sheets for these models for more details. No special tools are required. Just disassemble the ECM connector using a small flat screwdriver as shown below, remove seven wires from the ECM connector, insert these wires into our small mating connector, insert seven new wires from the Twin Tuner II into the ECM connector, and connect one ground wire. The unit is completely encapsulated and impervious to moisture. With a very low profile of only ½” and occupying a fraction of the space required by competitive products, you won’t have a problem finding a place to mount the unit.
