Crane Hi-4 High Performance Ignition Systems

Cranes high performance electronic ignitions have the entire unit mounted directly to the ignition timing plate for ease of installation and trouble free operation. They're available in single fire and dual fire "race" models.The HI-4 replaces theoriginal equipment (OE) electronic ignition system on1978 and later models as well as the points and mechanicaladvance on early models. HI-4 Single Fire Race Ignition are true single fire, even at cranking speed. Each cylinder is fired independently and only on the compression stroke. Single fire operation increases engine power at high RPM, improves starting, and reduces the likelihood of backfiring at low RPM. The HI-4 features state-of-the-art RISC microcontroller technology that allows adjustable advance and rev limit. A timing LED indicates static timing (top dead center) and gives diagnostic information. Two starting modes are provided: electric start and kick start. A tach output gives accurate tach readings even at the rev limit. They both feature fully adjustable advance curves, switching for kick and electric start, a tacho output , and a rev limiter that's adjustable from 4,000 to 8,000 rpm. The "race" single fire kit has adjustable rear cylinder timing and also has the necessary circuitry to correct the read out of the electronic tachos on late model bike. They fit all Sportster models from from 1983 thru 2003 and big twin models from 1984 thru 1999 that still have their original equipment ignition timing rotor in place.

Designed specifically to use all stock sensors, including the crankshaft position sensor. Two advance curve families. Features adjustable advance curves, single fire ignition with multi spark function, adjustable rev limiter, initial timing and rear cylinder timing offset. Works with original coils.

Free communication with new USB support - The new Power Commander USB will instantly and automatically connect to the Power Commander Control Centre software once it is installed. Simply "Power up" the unit and connect the supplied USB cable to the computer and PCIII USB. Automatic map retrieval upon connection - As soon as you connect the PCIII USB to the computer and launch the software, the map installed in the PCIII USB will be displayed. Onboard notes storage - The PCIII USB stores the notes from the map in the onboard memory. This makes it easy to see exactly which map is loaded. The notes, just as the map itself, are automatically retrieved upon connecting to the unit. Individual cylinder adjustment - All PCIII USB units have a "cylinder trim" adjustment feature that allows you to "offset" fuel to one or more cylinders. Additionally, for advanced users, the PCIII USB allows individual cylinder mapping. Now each cylinder can be mapped individually throughout the entire rpm/throttle position range. Enhanced "file compare"utility - The PCIII USB software now allows you to compare two map files without the Power Commander connected. There is a numerical display as well as a brand new graphical display. Easier to use "button adjustment" mode - The button adjustment has been made easier by introducing a startup delay. This gives the user enough time to start the bike and then switch the PCIII USB into "button adjust" mode. The ranges of the buttons are now displayed in the software. Simply connect the unit to the computer and press one of the buttons. Their ranges are shown on the screen. "Expansion port"for future upgrades and accessories - The "Expansion port" allows easy connection of upcoming accessories such as our new ignition module. 9V "Power Up" adapter - Every PCIII USB comes with a "Power up"adapter which allows users to program and interface with the Power Commander on their desktop without being connected to the bike.
