Two part numbers are available. The difference is in the mating connector. Model 1006 has a 7 pin connector and is intended for 1990-1994 H-D® motorcycles. Model 1007 has an 8 pin connector and is intended for later models. The external module offers easy plug-in installation and is ideal as a do-it-yourself item. Models 1006 and 1007 are intended for electric start applications only and are not compatible with kick start engines. The unit is constructed with a low profile machined billet aluminum housings. With the exception of external mounting and plug-in connection, all other features are the same as the Model 1005 internal ignition. Four rotary switches are used to set the operating modes (such as single or dual fire), adjust the timing advance, and select the RPM limit. Two diagnostic LEDs indicate status and the state of the vacuum switch (VOES). The status LED is also used for static timing, as it will flash when the engine reaches top dead center (TDC). You can adjust the slope of the advance curve. The user can optimize the timing advance for a wide range of applications - from stock to highly modified engines. For details, including advance curves, you can download the installation instructions from our website. Switch selectable single or dual fire mode allows you to initially install the unit and run it in dual fire mode with your stock coil. You can then easily upgrade to single fire by adding an appropriate coil. If you have a tach, it will continue to operate properly (some competitive systems require that you purchase a tach adapter). A special feature allows use of the tachometer wire for a link to a laptop PC when the engine is not running. While the customer does not require the PC link for any normal setup or operation, it can be used to access additional features for precise dyno tuning (such as programming a custom advance curve and setting rear cylinder timing offset). Our new USB interface (P/N USB-INTF) is used for this purpose. The USB interface is sold separately, but Windows compatible software is available for download. The software will operate in demo mode without an ignition attached.
Model 1007 External Ignition Installation The Model 1007 is highly recommended for demanding race applications where extreme engine temperatures would reduce the reliability of an internal module. Using our Model 1007 ignition system, J&P Cycles® just set a new national AMA speed record of 179.940 MPH in the 1350cc pushrod gas class at the 3rd annual Bub® International Land Speed Trials (September 2006 at the Bonneville Salt Flats Speedway).

PC Link Software for Programming Custom Advance CurvesPC Link software runs under Microsoft Windows XP/Vista/7. We no longer support older Windows versions. The PC Link Evo version allows the user to program Twin Tec Models 1005, 1006, and 1007 ignitions with custom advance tables and other engine parameters. An optional USB interface (P/N USB-INTF) is required to connect to the ignition module for on-bike programming. Bench top programming also requires a power adapter (P/N EVO-ADAPT). Advance table data can be edited by clicking on and dragging individual points on the chart display or you can directly enter numeric data on the spreadsheet grid. The advance table consists of 16 columns for RPM and 2 rows for manifold pressure (wide open throttle and cruise/decel) based on the VOES switch.
In addition to editing the advance table, you can also use PC Link to edit certain engine control parameters stored in the ignition module. You can set the number of cranking revolutions before the engine fires. Please note that kick start mode is not supported on Model 1006/1007 units. An engine builder can program Twin Tec units with a custom advance curve and then add a fixed RPM limit. For turbo charged or nitrous oxide injection applications, you can reconfigure the VOES input as a retard input. For more detailed information, please download our Turbo Boost and Nitrous Timing Retard Tech Note.
Minimum PC requirement is a 300 MHz Pentium with super VGA display (SVGA with 1024 x 768 pixel resolution). The PC must have a free USB port. If you have an older PC without USB capability, you will require special order PC link cable P/N 1005C. For more details, please refer to our PC Link Tech FAQ. PC Link 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 an ignition attached. For your convenience, we include a copy on CDROM when you purchase the optional USB interface. Download PC Link Evo Software and Instructions
Operating Statistics SoftwareThe Twin Tec Operating Statistics program runs under Microsoft Windows XP/Vista/7. We no longer support older Windows versions. This software allows engine manufacturers and tuners using Twin Tec motorcycle ignitions to download operating statistics from an ignition module and examine the data. The Operating Statistics program has the same PC requirements as described above for the PC Link software. Downloaded operating statistics are displayed as shown below. Total hours represents the total time that the engine was running. ID represents the firmware identification. This field typically includes the manufacturer (Twin Tec), model number, program revision and author's initials, and date. Elapsed time is displayed for 13 RPM bands from idle to 6999 RPM. The utility also displays the maximum engine RPM, time at the RPM limit (in seconds for better resolution) and the number of engine starts. All this data can be printed to provide a permanent record. Rev 6.0 units (manufactured after January, 2006) will also display elapsed time at wide open throttle (WOT) based on the VOES input. The data stored in the ignition module for maximum engine RPM and time at the RPM limit can be cleared. All other elapsed time and engine starts data is permanent. The user data field allows entry of up to 32 alphanumeric characters. User data is stored in the module EEPROM and can be used to represent information such as a serial number.
The elapsed time data in the various RPM bands can be displayed in the form of a histogram chart by clicking on the Histogram button. Clicking on this button causes the chart shown below to appear. Color coding of the bars helps to interpret the data. The idle RPM band is blue, normal operating RPM bands are green and high RPM bands are yellow and red. The chart is automatically scaled for best display.
Operating Statistics software is free! You can always download the latest version of the software and instruction sheet from our website.
