The Model 1005 internal ignition unit is triggered from the stock timing rotor at the end of the camshaft and mounted within the "nose cone" of the engine. This "nose cone" ignition is applicable to a wide range of H-D® engines. The Model 1005 ignition replaces all the H-D® OE ignition components including the bulky wiring harness and external module. The resulting clean appearance is especially desirable on custom motorcycles. The 50 states street legal Model 1005 EX version fits all 1970-1984 Shovelhead® Big-Twin® engines, 1986-93 883 XLH Sportster® engines, 1986-87 1100 XLH Sportster® engines, and 1984-1999 1340 Evolution® Big-Twin® engines and features advance curves suitable for all street applications including high compression engines. The Model 1005 Race version fits all 1970-1984 Shovelhead® Big-Twin® engines, 1971-1997 Sportster® engines, and 1984-1999 Evolution® Big-Twin® engines and includes race advance curves with a slightly wider adjustment range. The 50 states street legal Model 1005S EX fits 1998-2003 Sportster® engines (except dual plug 1200S) and directly plugs into the OE wiring harness (these late models came with an OE internal ignition). The Model 1005S EX has advance curves optimized for these Sportster® applications. The Model 1005 is constructed with a low profile machined billet aluminum housing. Four rotary switches are used to set the operating modes (such as single or dual fire, advance curve family, and multi-spark), 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 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. Kick Start CapabilityThe Model 1005 is primarily intended for electric start applications. However, Rev 7.0 units (manufactured after January, 2006) can be programmed for kick start mode by using our PC Link Evo software and optional USB interface. If you order on-line, you can add a note stating that you require kick start capability and we will program the unit for you at no extra cost. When programmed for kick start mode, the unit has zero cranking delay and a 30 second timeout before coil current shutoff. Sportster® 1200S with Dual Plug HeadsThe Sportster®1200S model with dual plug heads comes with a special ignition module, similar to that used on Twin-Cam 88® models. If you require a programmable aftermarket ignition for the 1200S, we have the solution. You can use our Model 1005 EX version (not the 1005S). The Model 1005 mounts in the nose cone. The original equipment coil has low resistance primary windings that are not compatible with the Model 1005. You must replace the original equipment coil with an aftermarket four tower coil, such as the Dyna DC6-4, that has 3 ohm primary resistance. Please refer to our Dual Spark Plug Tech Note for more details. You will have to remove the original equipment MAP sensor. You will also require our timing rotor (P/N 18004) and VOES switch (P/N 18010). Buell® BlastIf you require a programmable aftermarket ignition for racing the Buell® Blast, we have the solution. You can use our Model 1005 Race version that mounts in the nose cone in place of the Blast module. You must replace the original equipment coil with our mini coil (P/N 2006) that has 3 ohm primary resistance. You will also require our timing rotor (P/N 18004) and VOES switch (P/N 18010). Minor modifications are required to re-index the timing rotor and provide clearance in the Blast timing cover. Please refer to our Buell® Blast Tech Note for more details. Model 1005T - Special Version with Stage RPM Limiter for Drag RacingThe Model 1005T is a special version with a stage RPM limiter intended for drag racing applications. The purple/white wire normally used for the VOES connection is used to select between the stage and maximum RPM limit. The stage RPM limit is set by means of the two rotary switches on the module. The maximum RPM limit is programmed by means of the optional USB interface and PC Link Evo software. When the purple/white wire is grounded by means of a switch, the stage RPM limit is selected, otherwise the maximum RPM limit is selected. Please refer to the Model 1005 Two Stage Tech Note for details. 3005-IH - Special Kit for 1999-2003 American IronHorse® Motorcycles

The Model 1005 is a race proven product adaptable to a variety of applications. Chris Sansevere of Holeshot Cycles (Stuart, Florida) uses the Model 1005T with two stage RPM limiter on his 1998 Buell® S2 shown below running an 11.80 ET in the ET Class at the recent High Stakes Shootout in Las Vegas.
Attention: Former Customers of Crane Cams®Why should you upgrade from an earlier Crane HI-4 or buy the Model 1005 in place of the new Crane HI-4N? The simple answer is features and reliability. Major differences between the Model 1005 and Crane HI-4N and Model 1005 are summarized in the table below. For complete comparative details, read the Model 1005 and Crane HI-4N Teardown Report.
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 is required to connect to the ignition module for on-bike programming. Bench top programming also requires a power adapter (P/N 1005-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. An engine builder can program Twin Tec units with a custom advance curve and then add a fixed RPM limit. With race versions, you can offset the rear cylinder timing for maximum power during dyno tuning. 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. 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 7.0 units (manufactured after January, 2006) will also display elapsed time at wide open throttle (WOT) based on the VOES input, and elapsed time in various color coded temperature bands up to 150 deg C based on an internal temperature sensor. Significant time in the yellow or red bands indicates that the engine is running excessively hot. 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.
