    Beta testing a synchronising unit

    I've been testing a couple of these units and i'll bring them along for you to try out - I have a pre-production unit and a later pre-release unit.

    Be interesting to see if you can find any problems and your feedback on using them

    The Harmonizer

    The Harmonizer is a small, portable, battery-powered, Vacuum Multi-Tool intended to aid powersports engine tuning and diagnostics. It works for both carbureted and fuel injected motors. In addition to vacuum and RPM measurements in two distinctly different modes, a few utility/convenience features have been included

    The Harmonizer has two Vacuum modes that both include tachometer functions. Balancer mode and Gauge mode. The Harmonizer measures the period of the vacuum pulses to calculate RPM.
    Balancer mode displays the difference in vacuum at the two ports. There is a center-zero representation similar to an analog meter, and a numeric representation in the range of +/- 999mbar. A smiley appears if the vacuum difference is 0 +/- 25mbar. In Balancer mode the tachometer is calibrated for 4-stroke motors with one cylinder/intake. For 2-strokes or motors with 2 cylinders/intake you must divide the tachometer reading in half.
    Gauge mode is a heavily damped vacuum gauge, intended to measure vacuum on intakes that support one or two cylinders. Only one Harmonizer port is used. The other is left unconnected. A left-zero meter representation is displayed along with a numeric representation in the range of 0.00-29.00 inHg.
    Gauge mode can be used to adjust idle speed with the tach function and mixture (carburetor) with the tach and/or gauge function. Gauge mode can also a be a powerful diagnostic tool.
    In Gauge mode, if you use the yellow port, the tach is calibrated for 4-stroke motors, 1 cylinder/intake.
    In Gauge mode if you use the red port, the tach is calibrated for 4-stroke motors, 2 cylinders/intake.
    As in Balancer mode, for 2-strokes in Gauge mode you must divide the tach readings in half.

    Reliable, all electronic design, with digital signal processing and no moving parts.
    Large, easy to read, LCD display.
    Rugged housing with a clear polycarbonate top.
    Vacuum hoses are removable with convenient, color coded, Luer type connectors.
    Swivel-hook on top for hanging/attachment.
    Simple one-button interface. Press/release button and wait for Auto-Zero calibration. The unit is now ready in balancer mode.
    To access other modes and menu options, hold button pressed until desired function appears. Then release button.
    The button is recessed to prevent inadvertent activation and breakage.
    Auto Zero on power-up.
    Auto Range.
    Auto shutoff after 5 minutes of inactivity (except beacon and timed lantern modes).
    Battery Voltage Indicator.
    Automatic display backlight.
    Bright White LED included for convenience.
    Toggle LED on/off through menu or by a double press of the button for a quick flashlight function.
    Rally/Tour/Camping LED modes.
    Timed Lantern Mode illuminates the LED for 15 minutes then power-off. During timed lantern mode a single button press resets the timer to 15 minutes.
    Beacon Mode flashes the LED in a randomly selected, 5-flash, repeating sequence. Potentially useful as an emergency flasher or locating beacon. (No, I'm not kidding).
    Beacon mode does not time-out. It will persist until the mode is changed or the battery is depleted.

    I've know Airhead owners run off and hide at the sight of technology, so introduce it to us slowly.
    Do old airhead carbs produce enough suck to register on a dial?

    Ooh I like that.......

    I wonder if all the Mercury has evaporated from my Morgan yet.

    I never use gauges on an airhead, just use my ear(s). Only benefit is the gauges also have a rev counter next to the balance readout, so useful on those old GS's with no rev counter

    Plus i'd just like to see if anyone can find any faults using the units.
