TWIN SCAN 2 ABS - 15202

NEW HARLEY-DAVIDSON^® MOTORCYCLES USE THE SAE J1850 DATA BUS FOR COMMUNICATIONS BETWEEN THE ENGINE CONTROL MODULE (ECM) INSTRUMENT MODULE (IM) TURN SIGNAL/SECURITY MODULE (TSM/TSSM) ANTI-SKID BRAKING SYSTEM (ABS) AND DIAGNOSTIC SCAN TOOLS. THE TWIN SCAN II ABS IS A LOW COST SCAN TOOL THAT IS COMPATIBLE WITH 2001-2014 H-D^® FUEL INJECTED MODELS USING THE DELPHI^® FUEL INJECTION SYSTEM (INCLUDING V-ROD^®) WITH J1850 DATA BUS AND 2003-2006 CARBURETED MODELS WITH NEW 12 PIN IGNITION MODULE. PLEASE NOTE THAT 2011 AND LATER SOFTAIL^® 2012 AND LATER DYNA^® 2014 TOURING MODELS 1999-2003 CARBURETED TWIN CAM 88^® MODELS AND ALL MODELS WITH THE EARLIER MARELLI^® FUEL INJECTION LACK THE J1850 DATA BUS AND ARE NOT COMPATIBLE WITH THE TWIN SCAN.

THE TWIN SCAN II ABS CONNECTS TO THE FOUR TERMINAL DEUTSCH STYLE DATA LINK CONNECTOR ON THE H-D^® WIRING HARNESS AND REQUIRES A LAPTOP PC FOR USER INTERFACE AND DATA DISPLAY. YOU CAN READ AND CLEAR DIAGNOSTIC TROUBLE CODES FROM THE ECM TSM/TSSM SPEEDOMETER TACH (ON MODELS WITH IM DATA BUS) AND ABS (IF EQUIPPED). YOU CAN VIEW REAL TIME ENGINE DATA ON AN INSTRUMENT PANEL TYPE DISPLAY.

TWIN SCAN II SOFTWARE

THE TWIN SCAN SOFTWARE HAS FOUR MAJOR FUNCTIONS: READING AND CLEARING DIAGNOSTIC TROUBLE CODES DISPLAYING REAL TIME ENGINE DATA DISPLAYING LOGGED DATA AND ANALYZING AFR DATA (IF USED WITH OPTIONAL WEGO IIID).

DIAGNOSTIC TROUBLE CODES

THE UNIT WILL DISPLAY INFORMATION FOR ALL AVAILABLE MODULES (THIS INCLUDES THE SPEEDOMETER AND TACH ON MODELS WITH THE INSTRUMENT MODULE ON THE DATA BUS AND THE ABS). THE UPPER HALF OF THE SCREEN DISPLAYS THE SYSTEM ID AND CALIBRATION CODE INFORMATION. THE LOWER HALF OF THE SCREEN DISPLAYS DIAGNOSTIC TROUBLE CODES. EACH CURRENT AND HISTORIC TROUBLE CODE IS DISPLAYED ALONG WITH A BRIEF DESCRIPTION. THE SOFTWARE INCLUDES A DATABASE OF ALL DIAGNOSTIC TROUBLE CODES PUBLISHED BY HARLEY-DAVIDSON^®. YOU CAN THEN REFER TO THE H-D^® ELECTRICAL DIAGNOSTIC MANUAL FOR YOUR MODEL FOR DETAILED EXPLANATIONS AND TROUBLESHOOTING FLOWCHARTS.

YOU CAN PRINT THE DISPLAYED INFORMATION TO ANY WINDOWS PRINTER BY CLICKING ON THE PRINT CODES BUTTON. YOU CAN CLEAR ANY CODES BY CLICKING ON THE CLEAR CODES BUTTON.

ABS BRAKE BLEEDING FUNCTIONS

ABS BRAKE BLEEDING FUNCTIONS ARE ONLY AVAILABLE ON TWIN SCAN II ABS UNITS WITH VERSION 3.0 OR HIGHER FIRMWARE THAT SUPPORTS THE SPECIAL CODES USED FOR ABS BRAKE BLEEDING. IF YOU ATTEMPT TO USE THE ABS BRAKE BLEEDING FUNCTIONS WITH OLDER TWIN SCAN II UNITS AN ERROR MESSAGE WILL BE DISPLAYED. OLDER TWIN SCAN II UNITS CAN BE UPGRADED.

ABS BRAKE BLEEDING SHOULD ONLY BE PERFORMED BY A TRAINED AND EXPERIENCED MECHANIC. INDIVIDUAL FRONT AND REAR ABS BRAKE BLEEDING FUNCTIONS ARE AVAILABLE. IF YOU ARE ONLY SERVICING THE FRONT OR REAR BRAKE SECTION YOU DO NOT NEED TO BLEED THE OPPOSITE SECTION.

REAL TIME ENGINE DATA

YOU CAN DISPLAY REAL TIME ENGINE DATA ON AN INSTRUMENT PANEL TYPE LAYOUT WITH ROUND TACH AND SPEEDOMETER GAUGES AND BAR GRAPH TYPE GAUGES FOR MOST OTHER PARAMETERS. BAROMETRIC PRESSURE IDLE RPM AND SYSTEM STATUS ARE DISPLAYED IN ADDITIONAL BOXES. IF THE ENGINE IS NOT RUNNING MOST VALUES WILL APPEAR AS ZERO. THE SCREEN SNAPSHOOT BELOW SHOWS THE PARAMETERS DISPLAYED FOR A 2010 TOURING MODEL WITH ELECTRONIC THROTTLE CONTROL. A SUBSET OF THESE PARAMETERS IS DISPLAYED FOR OTHER ENGINE SYSTEMS.

2008-2013 TOURING MODELS FEATURE ELECTRONIC THROTTLE CONTROL. IN ORDER TO TEST AND TUNE THESE MODELS YOU NEED TO KNOW THE POSITION OF THE TWIST GRIP SENSOR (TGS) AND ELECTRONIC THROTTLE ACTUATOR (TPS). THE TWIN SCAN II ABS REAL TIME ENGINE DATA DISPLAY GIVES YOU THIS CRITICAL INFORMATION (TGS AND TPS IN THE UPPER RIGHT CORNER OF THE SCREEN).

YOU CAN LOG DATA DIRECTLY TO THE LAPTOP PC WHILE REAL TIME ENGINE DATA DISPLAY IS ACTIVE BY CLICKING ON THE START DATA LOGGING BUTTON. DATA IS LOGGED TO A BUFFER MEMORY ON THE LAPTOP PC THAT STORES 1450 DATA POINTS USING DATA LOGGING INTERVAL RANGING FROM 0.25 TO 2.0 SECONDS. YOU CAN START AND STOP DATA LOGGING AS DESIRED. THE LAST 1450 DATA POINTS WILL REMAIN IN THE PROGRAM DATA BUFFER.

DATA LOGGING

YOU CAN DISPLAY DATA DOWNLOADED FROM THE TWIN SCAN II ABS (IF THE UNIT HAS BEEN OPERATED ON THE MOTORCYCLE IN STAND-ALONE MODE) OR DIRECTLY LOGGED WHILE REAL TIME DISPLAY WAS ACTIVE. THE LOGGED DATA APPEARS ON A CHART RECORDER TYPE SCREEN. THE SCREEN SNAPSHOT BELOW SHOWS THE COMPLETE SET OF PARAMETERS. DEPENDING ON THE ACTUAL ENGINE CONTROL SYSTEM A SUBSET OF THESE PARAMETERS IS DISPLAYED. YOU HAVE A RANGE OF CAPABILITIES FOR ANALYZING AND PRINTING THE DATA. DATA CAN ALSO BE SAVED TO A FILE FOR FUTURE REFERENCE.

AFR DATA ANALYSIS

THE TWIN SCAN II ABS PLUS KIT INCLUDES THE WEGO IIID DUAL CHANNEL WIDE-BAND OXYGEN SENSOR SYSTEM. WHEN THE WEGO IIID IS CONNECTED THE TWIN SCAN II ABS WILL LOG ENGINE DATA ALONG WITH THE ACTUAL FRONT AND REAR CYLINDER AIR/FUEL RATIO (AFR). THE TWIN SCAN II ABS PLUS KIT IS AN IDEAL TUNING AID FOR USE WITH THE NEW SCREAMIN EAGLE^® PRO SUPER TUNER SCREAMIN EAGLE^® RACE TUNER (SERT) OR DYNOJET^® POWER COMMANDER^® ON FUEL INJECTED MOTORCYCLES. THE FIGURE BELOW SHOWS LOGGED AFR DATA THAT HAS BEEN ANALYZED AND DISPLAYED IN TWIN CAM FORMAT. YOU CAN SELECT FROM 11 DIFFERENT FORMATS FOR BOTH TWIN CAM AND VRSC (V-ROD&BDQUO&CENT) ENGINES. AFR DATA IS DISPLAYED WITH THE SAME RPM ROWS AND THROTTLE POSITION SENSOR (TPS) OR MANIFOLD PRESSURE (MAP) COLUMNS USED WITH MOST ENGINE MAPPING SYSTEMS.

AFR DATA DISPLAY

YOU CAN ALSO DISPLAY AND PRINT OUT THE REQUIRED VOLUMETRIC EFFICIENCY (VE) CORRECTION (IN PERCENT) BASED ON THE AFR COMMAND. THIS GIVES YOU THE REQUIRED FUEL CORRECTION. YOU CAN ADD DATA FROM AN UNLIMITED NUMBER OF FILES THAT YOU PREVIOUSLY SAVED. THE DATA WILL BE ANALYZED AND INCORPORATED INTO THE TABLE. CELLS THAT VARY MORE THAN &PLUSMN0.5 AFR FROM THE COMMAND VALUE ARE SHADED BLUE FOR RICH OR RED FOR LEAN.

VE PERCENT CORRECTION DISPLAY

YOU CAN USE TWO APPROACHES TO MAKE THE REQUIRED CORRECTIONS IN THIRD PARTY ENGINE MAPPING SYSTEMS. IF YOU HAVE MICROSOFT OFFICE WITH EXCEL YOU CAN DIRECTLY COPY AND PASTE DATA FROM THE TWIN SCAN II SOFTWARE TO AN EXCEL SPREADSHEET AND THEN COPY AND PASTE FROM THE EXCEL SPREADSHEET INTO THE ENGINE MAPPING SOFTWARE. IN THE TWIN SCAN II SOFTWARE YOU CAN SELECT A RANGE OF CELLS WITH THE MOUSE AND RIGHT CLICK TO BRING UP A COPY MENU. YOU CAN ALSO LEFT CLICK ON THE UPPER LEFT LEGEND CELL TO SELECT THE ENTIRE TABLE AND THEN RIGHT CLICK TO BRING UP THE COPY MENU. FOR MORE DETAILS ON USING EXCEL INCLUDING SAMPLE SPREADSHEETS PLEASE VISIT THE TWIN SCAN II TEC FAQ. ALTERNATELY YOU CAN MANUALLY ENTER THE REQUIRED CORRECTIONS IN THE ENGINE MAPPING SOFTWARE BY REFERRING TO THE PRINTED VE PERCENT CORRECTION TABLE AND MARKING OFF CELLS AS YOU EDIT THEM. WHEN USED WITH THE DAYTONA TWIN TEC TWIN TUNER THE PROGRAM CAN DIRECTLY EXPORT VE CORRECTION DATA TO TWIN TUNER DATA FILES.

THE TWIN SCAN II SOFTWARE USED FOR ALL VERSIONS OF THE TWIN SCAN II RUNS UNDER MICROSOFT WINDOWS XP/VISTA/7/8. WE NO LONGER SUPPORT OLDER WINDOWS VERSIONS. MINIMUM PC REQUIREMENT IS A 300 MHZ PENTIUM WITH SUPER VGA DISPLAY (SVGA WITH 1024 X 768 PIXEL RESOLUTION). THE TWIN SCAN II ABS CONNECTS TO THE PC BY MEANS OF A USB INTERFACE. A USB CABLE IS SUPPLIED WITH THE UNIT. THE PC MUST HAVE A FREE USB PORT. IF YOU HAVE AN OLDER PC WITHOUT USB CAPABILITY YOU CANNOT USE THE TWIN SCAN II ABS. FOR MORE DETAILED PRODUCT INFORMATION WE SUGGEST THAT YOU DOWNLOAD THE TWIN SCAN II SOFTWARE AND INSTRUCTIONS. THE SOFTWARE DOWNLOAD INCLUDES SAMPLE FILES WITH ACTUAL DATA.

EXHAUST SNIFFERS

THE TWIN SCAN II ABS PLUS KIT CAN BE USED WITH AN EXHAUST SNIFFER THAT ALLOWS TEMPORARY INSTALLATION ON MOST MOTORCYCLES FOR TUNING AND DIAGNOSTIC PURPOSES. JIMSUSA OFFERS AN EXHAUST SNIFFER P/N 777 SUITABLE FOR USE WITH THE WEGO. FOR ADDITIONAL INFORMATION ON DO-IT-YOURSELF SNIFFERS REFER TO OUR MOTORCYCLE EXHAUST SNIFFER TECH NOTE.

2010 AND LATER TOURING MODELS AND ALL 2012 AND LATER MODELS ARE EQUIPPED WITH MINIATURE 12MM OXYGEN SENSORS. THE BOSCH LSU 4.2 WIDE-BAND OXYGEN SENSORS USED WITH THE TWIN SCAN II ABS PLUS KIT ARE 18MM AND WILL NOT FIT. SMALLER WIDE-BAND SENSORS ARE NOT AVAILABLE. HOWEVER THERE IS A SOLUTION. BAY AREA PERFORMANCE CYCLES (PHONE: 650-969-0372) SELLS AN OXYGEN SENSOR MANIFOLD KIT (SUGGESTED RETAIL PRICE $469.00) THAT ALLOWS EASY INSTALLATION OF BOSCH LSU 4.2 WIDE-BAND SENSORS ON ANY EXHAUST SYSTEM FOR TESTING PURPOSES. THE PROCESS INVOLVES DRILLING SMALL HOLES AND USING A SPECIAL TOOL TO INSTALL THREADED FITTINGS FOR THE SENSOR MANIFOLDS. AFTER TESTING BUTTON HEAD STAINLESS STEEL SCREWS ARE INSTALLED IN PLACE OF THE SENSOR MANIFOLDS AND THE HEAT SHIELDS ARE REINSTALLED.
