5/11 9000-6320 1 1 Installation Instructions for HI-6S IGNITION For more information, see www.cranecams.com CAUTION: READ INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION. OVERVIEW - READ FIRST!! Before proceeding with the HI-6S installation, read the intro- ductory material below and on pages 2-4. Then use the Appli- cations Index to find the appropriate section for your vehicle. INTRODUCTION Crane HI-6S part number 6000-6300 is for general purpose applications and includes a universal adapter harness. Part number 6000-6301 includes a plug-in adapter harness for Ford TFI-IV applications. Part number 6000-6302 includes a plug-in adapter harness for late model GM applications with dual plug coil. The Crane HI-6S is a multi-spark inductive ignition spe- cially optimized for street driven performance vehicles with an engine redline below 8,000 RPM. A RISC micro- controller manages all functions of the HI-6S including the stage rev limiter and timing retard functions. If rev limiter or timing retard functions are not required, the HI-6S also has an anti-theft function that uses a switch hidden under the dash to select a very low rev limit to keep the engine from starting. While the HI-6S has a range of built-in retard functions includ- ing boost proportional retard using an optional boost sensor (P/N 9000-0110), use of these built-in retard features pre- cludes use of the built-in rev limiter. If an application requires both rev limiting and retard, you will require the optional TRC-2 Timing Retard Control (P/N 6000-6425). Refer to page 9. Daytona Beach, FL 32117 | cranecams.com | 866-388-5120 | Fax 608-627-0480 The HI-6S is intended for use with vehicles equipped with original equipment (OE) electronic ignition and computer engine control. It can be directly triggered from the output of the OE electronic ignition on most 1981-95 cars and 1986-95 light trucks with dis- tributor ignition and computer engine control. Most 1975 to 1980 cars (1985 for light trucks) use magnetic trigger and will require the HI-6R (P/N 6000-6400). The HI-6S also can be installed on pre-1975 vehicles with OE breaker points by means of an opti- cal trigger conversion (refer to Crane catalog for details). Crane LX91 or PS-91 coils are recommended for optimum perfor- mance, however the HI-6S is compatible with most OE coils. The HI-6S is not compatible with distributorless ignitions or 1996 and later vehicles with OBD II On Board Diagnostic system. The HI-6S is 50 states legal (California Air Resources Board E.O. D-225-59) for vehicles without OBD II. INTELLIGENT MULTI-SPARK Multi-spark is generated by repeatedly turning the coil current on and off during the spark sequence. At low RPM, during cranking, the HI-6S generates up to 12 sparks. This assures quick starting even under the most adverse conditions. At idle and cruise, the number of sparks fired is adjusted to maintain a total spark duration of about 20 degrees (crank- shaft), assuring smooth idle, improved throttle response, and eliminating the lean surge characteristic of some late model emission controlled vehicles. During acceleration at higher RPM levels, the HI-6S generates a single powerful spark with about twice the spark gap energy of most OE systems (with use of recommended LX-91 or PS-91 coil). SWITCH SELECTABLE RETARD AND REV LIMIT MODES Two rotary switches shown in Figure 1 are used to select the operating modes. Please note the HI-6S only reads the switches when the ignition key is first turned on. If you change switch settings, you must cycle the ignition key off and on again in order for the unit to read the new settings. Modes are based on switch settings as follows: 00 Diagnostic mode. Disables all rev limit and retard functions. Also disables multi-spark. 01-20 Digital retard mode with 1 to 20 degrees retard acti- vated by an external switch connected to the yellow/ white wire (refer to Figure 2). Retard value directly corresponds to switch setting (i.e. 04 = 4 degrees) APPLICATIONS INDEX All except Ford, GM, and Honda.......................
