iPhone tachometer

    There is now an iPhone app to check your tachometer. It is called "Engine RPM"
    and it is in the Utilities category in the App Store. It uses the sound of the
    engine to determine RPM as accurately as an optical tach. It works on any
    engine that makes noise: small planes, motorcycles, R/C models, etc.

    This app is based on our "RPM from Sound" freeware Pocket PC app that has been
    available for years. But this iPhone app is more reliable, easier to operate,
    and covers the range 500 to 90,000 RPM.

    usually I would say **** off spammer bitch...but this kinda sounds
    interesting

    does it would on and iPod touch?

    and anyone else, do apps designed for the iPhone work on the iPod
    touch? I have no need for an iPhone cos I have to have a Crackberry
    for work, but I am hearing pretty good things about the Touch and at
    1/3 the price.

    Hehe
    Check out their *other* app, a piano tuner.

    No wait - I'll save you the trouble. It's $350.

    Straight up. Not $3.50, three hundred and fifty dollars.

    (well - less one cent)

    Still think $12 is steep?
    A plastic cable clip for my Bonnie cost me that much.

    All things are relative.
    $12 is a lot compared to $0.00, but not much compared to $350.

    BTW - tach app is pretty much meh.
    Only digital display, and takes some fiddling to get it to settle down on
    the Bonnie.

    Definitely not to be relied on.
    Interesting, though, and actually pretty clever.

    The iPod touch can access the app store as long as you are in a wifi
    area and it will run all of the apps that the iPhone 3G will run that
    don't require mobile phone access.

    There are some apps that require the GPS/compass hardware that is only
    in the newer iPhone 3GS (eg the Tom Tom GPS software).

    But the iPod touch will run the vast majority of apps from the app store.

    what is a Tachometer worth..?

    or, what is a audible Tachometer worth?

    I need one, so "if" I had a iPhone/iTouch, $12 would be a bargain

    No, not at the moment.

    The microphone is part of the mobile phone hardware.

    There are persistent rumors that the next version will have.

    I almost forgot but there is an option to add an external microphone
    (the Apple headphone/mics won't work in the touch as they rely on
    internal hardware).

    cool....ta

    I wonder if anyone makes this software for PC? I have a few spare
    lappys at home...


    I have to do some fine tuning on the CB, and its the kinda thing where
    you have to turn screw "a" and see if the rev rise or fall by 50rpm...
    so a accurate tacho is a must

    I am a novice at carbies, so guessing inst really an option ATM

    Rev counters are used for purposes other than looking pretty on the
    instrument panel.

    If it is accurate enough, for engine tuning you can not see the the dash
    tacho from the engine.

    Last time I looked, the local bike shop wanted something like $250 for a
    tacho for my Bonnie. About half that if I import a third party one from the
    US, and invalidate the warranty installing it.

    $12 is nothing.

    you have never worked on, restored or rebuilt a bike/engine/carby
    then?
    ever built and played with RC aircraft?


    you are, like some others in this thread are thinking a Tacho is only
    use to change gears

    people who work with engines would find this app quite useful for
    tuning

    ebay is full of optical/laser tachos
    http://shop.ebay.com.au/?_from=R40&_trksid=m38&_nkw=Digital+Tachometer
    just because you wouldn't use one, and all the Vehicles you have had a
    standard Tacho, then no one need these either?

    I could go on for hours about the test equipment that I use that
    almost all people in the NG would go huh? and guess what, the prices
    are expensive, welcome to the world of test equipment, its pricey.

    My daily test equipment is valued at around $30k and thats so people
    can surf p0rN and make phone calls, I hate to think of the value of
    the some of the stuff in the Exchange.

    but I wouldnt use a iphone for testing would I? I dont own a iPhone,
    but I use my crackberry to control a wireless ADSL modem that is
    networked (and gaffer taped) to a SHDSL modem for testing purposes,
    its great for the simple faults like authentication and sync issues..

    back to motorcyles

    here is the procedure to adjust the pilot screws on a NT650 (the
    quickest I could find on the net, same as most I have seen)

    1. Turn each pilot screw clockwise until it seats lightly and back
    it out to the specification given.
    This is an initial setting prior to the final pilot screw
    adjustment.

    INITIAL OPENING:
    49 St. model California model
    '88 2-1/8 turns out 2-1/2 turns out
    After
    '88 Front: 1-1/2 turns out
    Rear: 1 turns out 1-3/8 turns out
    CAUTION
    * Damage to the pilot screw seat will occur if the pilot
    screw is tightened against the seat.

    2. Warm up the engine to operating temperature.
    Stop and go riding for 10 minutes is sufficient.
    3. Attach a tachometer according to the manufacturer's
    instructions.
    4. Adjust the idle speed with the throttle stop screw.
    5. Turn each pilot screw 1/2 turn out from the initial setting.
    6. If the engine speed increases by 50 rpm or more, turn each pilot
    screw out by an additional 1/2 turn until engine speed drops by 50 rpm
    or less.
    7. Adjust the idle speed with the throttle stop screw.
    8. Turn the rear cylinder carburetor pilot screw in until the
    engine speed drops 50 rpm.
    9. Turn the rear cylinder carburetor pilot screw 1 turn out from
    the position obtained in step 8.
    10. Adjust the idle speed with the throttle stop screw.
    11. Perform steps 8, 9 and 10 for the front cylinder carburetor
    pilot screw.
    12. Drive new pilot screw plugs into the pilot screw bores with a 7
    mm valve guide driver (P/N 07942 - 8230000). When fully seated the
    plug surfaces will be recessed 1 mm.




    think outside the square Nev :)
