DIYAutoTune Smart Coils by AMP EFI produce CDI-level spark energy--without a CD ignition module. They're manufactured with a 19 amp IGBT ignitor built in and can be driven with a 5 V logic level output. Normally, you would use Smart Coils for distributor-less ignitions, such as a coil-per-plug application; however they can be fired sequentially or every crank revolution (wasted spark coil per plug). Smart Coil specs: * Minimum voltage output (no load, at recommended dwell): 40,000 V * Output energy: 103 mJ * Spark duration: 2.9 ms * Primary resistance: 0.5 ohms (not directly measurable) * Primary inductance: 4.8 mH (not directly measurable) * Secondary resistance: 8,500 ohms * Secondary inductance: 22.5 H * Turns ratio: 71.1 * Maximum current: 19 amps * Maximum battery voltage: 17 V * Nominal dwell: 3.0 ms * Maximum recommended duty cycle is 40 percent * Requires HEI-type plug wire ends/boots

DIYAutoTune hall effect sensors can be used as crankshaft or camshaft position sensors, and are also suitable for use as vehicle speed sensors (VSS). The threaded bodies feature a red anodized finish and includes two M12 mounting nuts. They run off 5 to 24 V and gives a nice square wave, so there's no variable voltage issues. Specifications are: * Operating voltage: 5 to 24 V * Maximum over-voltage and reverse voltage: +30 to -24 V * Maximum supply current required: 6 mA * Maximum output current sinking: 20 mA * Output type: Open collector * Triggering options: Magnet or ferrous metal * Maximum frequency: 15 kHz * Temperature range: -40 to +125 degrees C * Nominal air gap: 1.5mm * Thread pitch: M12 x 1mm * Overall length: 65.5mm, not including wires * Sensor material: Aluminum * Sensor orientation: Not directional * Recommended tooth size is a rectangle measuring at least 2.5mm x 6.35mm, with a 5.0mm tooth height.
