11/10 9000-6320 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 introductory material below and on pages 2–4. Then use the Applications Index to find the appropriate section for your vehicle. INTRODUCTION Crane HI-6S part number 6000-6300 is for general purpose applications. Part number 6000-6301 is for Ford TFI-IV appli- cations. Part number 6000-6302 is for late model GM applica- tions 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 microcontroller 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 14. The HI-6S is intended for use with vehicles equipped with original equipment (OE) electronic ignition and computer Daytona Beach, FL 32117 www.cranecams.com / Phone: 866-388-5120 / Fax: 608-627-0480 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 distributor 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 optical trigger conversion (refer to Crane catalog for details). Crane LX91 or PS-91 coils are recommended for optimum performance, however the HI-6S is compatible with most OE coils. The HI-6S is not compat- ible 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 (crankshaft), assur- ing 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 recom- mended LX-91 or PS-91 coil). SWITCH SELECTABLE RETARD AND REV LIMIT MODES Two rotary switches shown in Fig. 1 are used to select the oper- ating modes. Please note the HI-6S only reads the switches when the ignition key is first turned on. If you change switch set- tings, 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 activated by an external switch connected to the yellow/white wire (refer to Fig. 2). Retard value directly corresponds to switch setting (i.e. 04 = 4 degrees) APPLICATIONS INDEX All except Ford, GM, and Honda.......................
