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

mh

 

thanks for that

but has the Touch got a Mic on it?

mh

 

No, not at the moment.

The microphone is part of the mobile phone hardware.

There are persistent rumors that the next version will have.


G-S

 

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).

who was talking about a modern bike?

think '79 vintage

you guys go back to sipping lattes at your service dealers waiting
rooms will you

(do people think outside the octagon inside the pentagon surrounded by
the square anymore?)

 

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


mh

 

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.

 

Oops, in a car.

 

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.

optical... no good, you need to point it at something moving, fine
with cars that have an exposed harmonic balancer or RC plane props
