TWIN TUNER II

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&APOST 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.

EASY INSTALLATION

INSTALLATION TAKES ONLY 10-15 MINUTES AND IS VERY EASY WITH NO SPLICING CUTTING CRIMPING OR BULKY INTERCONNECTIONS. ALL ACCESS IS 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 &FRAC12" AND OCCUPYING A FRACTION OF THE SPACE REQUIRED BY COMPETITIVE PRODUCTS YOU WON&APOST HAVE A PROBLEM FINDING A PLACE TO MOUNT THE UNIT.

BASIC TUNING

THE TWIN TUNER II USES UP/DOWN PUSHBUTTONS AND A LED DISPLAY TO SELECT AND CHANGE THE FUEL TRIM AND SPARK RETARD PARAMETERS LISTED IN THE TABLES BELOW. NOTE THAT THE LED FLASHES TO INDICATE NEGATIVE VALUES. YOU CAN MAKE CHANGES ON-THE-FLY WITH THE ENGINE RUNNING.

TWIN TUNER II FUEL TRIM

TWIN TUNER II SPARK RETARD

THE TABLES ABOVE SHOW THE ENGINE OPERATING RANGES AFFECTED BY FUEL TRIM AND SPARK RETARD VALUES IN TERMS OF RPM AND THROTTLE POSITION SENSOR (TPS) VALUES FOR TWIN CAM AND SPORTSTER^® VERSIONS. RPM RANGES ARE EXTENDED FOR THE V-ROD&BDQUO&CENT VERSION. TO PROPERLY TUNE AN ENGINE YOU NEED TO KNOW WHAT FUEL TRIM AND IGNITION RETARD VALUES ARE REQUIRED. TUNING GUIDELINES AND RECOMMENDED INITIAL SETTINGS FOR COMMON APPLICATIONS ARE GIVEN ON THE TWIN TUNER TECH FAQ.

ADVANCED MODE

THE TWIN TUNER II ALSO HAS AN ADVANCED MODE WHERE YOU CAN USE THE OPTIONAL USB INTERFACE AND WINDOWS SOFTWARE TO CHECK AND OBSERVE SYSTEM OPERATION (TUNER LOG) AND MAKE PRECISE FUEL AND SPARK RETARD ADJUSTMENTS (PC LINK TUNER). SETUP FILES ARE AVAILABLE FOR COMMON APPLICATIONS.

TWIN TUNER II SETUP FILES

THE SETUP FILES ARE SAVED AS A ZIP ARCHIVE FILE THAT YOU CAN DOWNLOAD BY CLICKING ON THE LINK ABOVE.

PC LINK TUNER SOFTWARE

PC LINK SOFTWARE RUNS UNDER MICROSOFT WINDOWS XP/VISTA/7/8. THE TWIN TUNER II CONNECTS TO THE PC BY MEANS OF AN OPTIONAL USB INTERFACE (P/N USB-INTF). THIS USB INTERFACE ALSO WORKS WITH ALL DAYTONA TWIN TEC ENGINE CONTROLS (IGNITION AND FUEL INJECTION SYSTEMS).

YOU CAN EDIT VARIOUS TABLES AND PARAMETERS. 3D TABLES ARE USED FOR FRONT AND REAR CYLINDER FUEL TRIM AND SPARK RETARD. 3D TABLES ARE ACCOMPANIED BY CHART DISPLAYS THAT HELP VISUALIZE THE DATA. YOU CAN PRINT THE DATA ASSOCIATED WITH AN ACTIVE TABLE OR TWIN TUNER II PARAMETERS BY USING THE APPROPRIATE PRINT COMMAND FROM THE FILE MENU. YOU CAN OPEN AND SAVE TUNING FILES TO DISK.

DATA EXPORT AND IMPORT BY MEANS OF COPY AND PASTE

YOU MIGHT WANT TO EXPORT OR IMPORT 3D TABLE DATA TO OR FROM ANOTHER APPLICATION SUCH AS MICROSOFT EXCEL AND OTHER PROGRAMS WITH TABLES THAT SUPPORT COPY AND PASTE OPERATIONS. YOU CAN DIRECTLY COPY AND PASTE DATA TO AND FROM THE PC LINK TUNER PROGRAM. IN THE PC LINK TUNER PROGRAM YOU CAN SELECT A RANGE OF CELLS WITH THE MOUSE AND RIGHT CLICK TO BRING UP A COPY AND PASTE MENU. WHEN YOU PASTE DATA INTO THE PC LINK TUNER PROGRAM THE DATA IS AUTOMATICALLY CHECKED AND ANY OUT-OF-RANGE DATA CORRECTED.

TUNER LOG SOFTWARE

WHEN THE ENGINE IS RUNNING YOU CAN DISPLAY REAL TIME ENGINE DATA ON AN INSTRUMENT PANEL TYPE SCREEN BY USING THE VIEW REAL TIME DATA COMMAND ON THE VIEW MENU.

YOU CAN ALSO CHECK PROPER OPERATION OF THE THROTTLE POSITION SENSOR (TPS) WHEN THE RUN/STOP SWITCH IS ON (ENGINE NOT RUNNING). ROTATE THE THROTTLE THROUGH THE FULL RANGE OF MOTION. THE TPS VALUE SHOULD GO FROM ZERO TO 100.

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.

TUNER LOG SOFTWARE IS FREE! YOU CAN ALWAYS DOWNLOAD THE LATEST VERSION OF THE SOFTWARE AND INSTRUCTION SHEET FROM OUR WEBSITE. THE SOFTWARE WILL RUN IN DEMO MODE WITHOUT A TWIN TUNER II SYSTEM ATTACHED. FOR YOUR CONVENIENCE WE INCLUDE A COPY ON CDROM WHEN YOU PURCHASE THE USB INTERFACE.
