Evosport is pleased to offer the Nology PDA Dyno for most OBDII automobiles. The PDA Dyno attaches to your own PDA (Palm, Handspring Visor, Sony Clié) to the cars OBD II connector under the dash using the supplied OBD II compliant cable (supports cars 1996 and newer). Once attached, your PDA is transformed into a data aquisition system that is able to do a variety of tasks; including dynoing your car! The PDA Dyno normally sells for $348.50 plus $30 for an in-car mount, however we are pleased to offer both items together on sale for the introductory price of $340!

Functioning as a data logger, your PDA is able to obtain accurate 0-60 mph and 1/4 mile times, as well as calculate hp and torque on a dyno chart with results within 1% accuracy. These calculations are mathematically computed based on a few parameters (vehicle weight, altimeter pressure, temperature, coefficient of drag, and gear ratio), which while reading the car's acceleration and RPM's, allows realtime dyno charts to be calculated and graphed as well as later being transferred to your computer.

Additionally, the PDA Dyno functions as a Diagnostic Trouble Code scanner, and allows you to scan and clear check engine lights. All OBD II supplied data can be recorded and stored. Record all data during a road-race, or record your cars gas mileage (mpg) for a specific trip.-- A standard 8 MB PDA can hold hours of driving data (depending on free memory space).

Product support includes a 1 year limited warranty and life-time software upgrades. Remember Neither Evosport nor Nology supports street racing. Obey all laws when using the PDA-Dyno. The PDA-Dyno is not intended for street use. Use only in designated areas, closed courses and racetracks. Use the PDA-Dyno with caution and emphasis on safety. Do not operate the PDA-Dyno™ while driving. Do not take your eyes of the road.

Below are some of the important functions of the PDA Dyno:


---------------------
Dyno Setup Screen

Dyno Setup Used On Run This shows the Dyno Setup parameters used on a run. Parameters such as vehicle weight, elevation and humidity are all saved at the time the run was performed. Get current weather conditions in your area here . Get vehicle data here.
File – file name.
Weight – weight of the vehicle including passengers.
Gear Ratio – the overall gear ratio of the vehicle, which includes transmission and axle.
Tire Diameter – the vehicle tire diameter.
Temp – current outside temperature.
Elevation – current elevation.
Humidity – current outside humidity.
Pressure– current outside altimeter pressure available here. Altimeter pressure is different than barometric pressure.
Drag – drag coefficient of vehicle. Available data here.
Frontal Area – frontal area of vehicle. Available data here.
Note – an optional text note.

---------------------
Gear Ratio Setup Screen

The Gear Ratio screen measures the overall gear ratio of the vehicle and computes a tire diameter.
Tire Diameter
Most car tire sizes are listed as width, ratio, and rim diameter (e.g. 205/65 R15). Enter the tire size using the Width, Ratio, and Rim Dia drop down lists. .
Measuring Overall Gear Ratio
The overall gear ratio is a combination of the transmission and the final drive gear ratio and tire size.
The Status field lists the current status of the gear ratio run, either:
Idle – no data is being gathered.
Countdown to Start – shows seconds until data collection begins.
Collecting Data – vehicle data is being recorded.

---------------------
Power vs. Torque Screen

The Power vs. Torque screen analyzes data gathered from a vehicle run. The graph shows horsepower/torque over engine RPM. Vertical axis 1 shows power from 0 to 500 HP. Vertical axis 2 shows torque from 0 to 500 torque. Horizontal axis shows engine RPM from 1000 to 11000.
The graph control support many features such as zoom and scroll.
The Run button is for starting a dyno run. The Stats button shows horsepower and torque statistics.

---------------------
Acceleration Statistics

The Acceleration Statistics screen computes times and horsepower values based upon how fast the vehicle accelerates.
File – Acceleration run file name.
Top Speed – maximum speed achieved during the run.
0 to 60 Time – how fast in seconds the vehicle traveled from 0 to 60 MPH.
1/8 Mile Speed – how fast at the 1/8-mile mark.
1/8 Mile Time – time in seconds, the vehicle traveled a 1/8-mile.
1/4 Mile Speed – how fast at the 1/4-mile mark.
1/4 Mile Time – time in seconds, the vehicle traveled a 1/4-mile.
1/4 Mile HP – a rough calculation of horsepower based strictly on 1/4-mile time and vehicle weight.
N/A will be displayed in a column if the vehicle didn’t travel far enough to compute the statistic.

---------------------
Fuel Economy

The Fuel Economy screen computes instantaneous and trip MPG. One other sensor can also be monitored along with Fuel Economy.
Pressing the Trip button toggles the Miles Per Gallon view between instantaneous mode and trip mode.
The fuel economy feature is only available on vehicles equipped with a mass airflow sensor (MAF). The Sensor Select screen has a list of sensors supported by your vehicle.

---------------------
Graph/Dual Graph


Graph - displays real-time sensor measurements in a graphical format. A large trace buffer, pause, and zoom make analyzing data a breeze.

All live data screens can record and playback data obtained from the vehicle. 0.5MB of Palm RAM will store approximately 1 hour of recording at the fastest sample rate.

Slide a marker around with the stylus to get an exact data point anywhere on the graph.

---------------------
Diagnostic Trouble Codes

Diagnostic Trouble Codes - displays the pending and stored Diagnostic Trouble Codes (DTC). If the vehicle’s Check Engine or Service Engine Soon light on the instrument panel is illuminated, a Stored DTC will be displayed. Pending DTC’s do not necessarily indicate a faulty component/system. If the vehicles test results indicate a failure after additional driving, then the Check Engine light will be illuminated and a DTC will be set in the stored DTC’s column.

---------------------
DTC Lookup

DTC Lookup - tap a DTC to show a textual description of a numeric trouble code.

---------------------
DTC Freeze Frame Log

Freeze Frame - displays the vehicle's freeze frame log. When a Diagnostic Trouble Code occurs that illuminates the Check Engine light, the vehicle’s computer saves the current values of the vehicle sensors at the moment the error occurred.

---------------------
Live Data Meter

Meter - displays real-time sensor reading from the vehicle in large, easy-to-read numbers at a distance. Up to two sensors can be monitored simultaneously.

---------------------
Sensor Select

Sensor Select - this dialog displays when the Edit... button is pressed to provide sensor selection, units of measure, and polling speed among other things.

---------------------
Real Time Sensor Monitoring

Displays real-time sensor reading from the vehicle in list format. Up to five sensors can be monitored simultaneously.

---------------------
Oxygen Sensor Results

Oxygen Sensor - displays the vehicle’s oxygen sensor test results. Not all test values are applicable to all vehicles. Therefore, the list generated varies depending on vehicle.

Many of the above features may rarely be used by most individuals, but the dyno function is something I will be using every day! With the PDA-Dyno, you can verify firsthand whether the upgrades you purchase deliver the gains promised; and you won't have to pay for dyno time. For a limited time, you can purchase the PDA-Dyno with Mag-Mount for the introductory price of $340 (almost a $40 savings). If you have any comments or questions feel free to ask!

Thanks,
Ben

You made my day man, that's too much!!

tifosiv122

Does it work with the Clie NX series?

Erik

JamE55

Awsome! So what exactly do you get for $340.00? The PDA and software or what?

tifosiv122

I doubt it..... "The PDA Dyno attaches to your own PDA"

Since the accelleration and HP data is not available from obd2 port and things like RPM, vehicle speed have too much of a delay out the port to be accurate enough for these calculations it sounds like they just combined an ordinary obd2 scanner with the accelerometer like on the g-tech pro. I've tried getting 0-60 times using an obd-2 scanner and it's impossible, the data on our cars isn't updated fast enough and not all sensors poll at the same exact time. Also, unless you already own a pocket PC this will set you back about $600 where a g-tech pro is about $100 on ebay with similar claims in accuracy.

otoupalik

Of course engineers in the industry (the experts at Powerchips and our own Vadim) TOTALLY and 100% DISAGREE with your commnets, but oh well.

Guys, we would not use it, receommend it or sell it if it as junk.

Use your own judgement, call Ben and ask about it or take Carl's post as gospel - your call.

Thanks

Brad

tifosiv122

Do you know if it will work with the NX clie?

Erik

MacedoMS

Does this software display all sensor values as well as everything listed above? Very cool stuff!

Buellwinkle

You want to see cool stuff, check out http://www.davisnet.com/drive/produc...ive.asp?grp=c1

This device is the size of a plug, snaps into the obd2 connector and does all the same things any obd2 scanner can do and then you can look at the info later on your PC.

tifosiv122

Have you used this? I saw it in person and I wasn't impressed. Since you can't view in real time, its hard to test-tune or even monitor instanly...its good for an overall picture if you know what I mean.

Erik

otoupalik

This one Carl is talking about is a toy-nothing more.

Sleestack

Awesome.
Brad, I will definitely want one when my car is ready.

levelr123g

i think i would also agree with buell. you cant take into account factors such as

grade of road (incline/decline % )

wind speed

rolling resistance of different tires, and different roadways, and differnt inflation rates on tires.

drivetrain loss of different vehicles, even though they are the same vehicle every vehicle will have a differnet loss

plus how is the unit measuring acceleration? a gtech is an accelerometer, where as my palm does not have an accelerometer in it.

if it were this easy to get these numbers then why would they continue to make chassis dynos, and why would they cost so much. this is nothing more than an obd reader that makes mathematical calculations based on various inputs. im not disputing its validity on the other readings such as temp, o2 content etc., i am however saying that the dyno part cannot be accurate. hell with a g-tech, i can get my c320 to read 500 hp if i want to , just change the numbers or the angle of the gtech.

Mach430

Yes, it does work on the Clie. When you place your order, I will ask exactly which model PDA you have, as there are different kits for each one.

nov0798,

You are completely right. A chassis dyno is much better; the PDA-Dyno only comes within 1% accuracry. There are several factors that one needs to consider when comparing the two.

First, a chassis dyno costs money each and every time. You can not purchase it and put it in your car to use at any time you desire.

Second, no, the PDA-Dyno is not completely accurate. However, properly calculated, it does come within 1%.

If you purchase the PDA-Dyno witih the intentions of cheating yourself into believing false power numbers, then by all means, do as many up-hill/down-hill acceleration runs as you choose. My intentions in providing this were to allow people to accurately determine power figures for their car.

Rolling resistance of the tires is calculated during the gear test function, which takes about 15 seconds of your time. If you change your tires, simply redo the gear test.

Wind speed can play against the accuracy of the numbers, but nothing is perfect. You may have to wait until there are low-speed winds to accurately obtain your numbers.

The PDA-Dyno makes its HP/Torque calculations using the speed/rpms the car displays. The G-Tech displays numbers based on how many G's the accelerometer is feeling. Some people swear by it, others do not. They are good for before and after comparisons, but this is more of a toy, whereas the PDA-Dyno would be a tool.

Properly configured, the downside of PDA-Dyno readings is that it can only be about 99% accurate. The PDA-Dyno will not display your a/f ratio, and is not more accurate then a chassis dyno, but it is an easier, reliable solution.

Thanks,
Ben

tifosiv122

Just ordered one...thanks Ben!
I have been waiting for something like this for a while.

Erik

nubomb

That looks pretty cool. So what is the PDA Dyno, additional software for the PDA or is it more then that?

Also did you notice any differences from various PDA models, do some perform better or easier to use then others?

Thanks.

Mach430

The PDA-Dyno includes:


PDA-Dyno™/OBD II Interface Box
OBD II Interface Cable
PDA Data Cable
Software CD (includes manual)
Any PDA with Palm OS 3.0 or higher will work


Any PDA that it is compatable with will suffice, however you will benefit from ones with better displays. Below is a list of some of the PDA's recommended if you need to purchase one:

Palm M130 -$199.99 massive memory, color screen and rechargable batteries
Palm M105 - $99.00 -affordable, no color display
Sony Clie - $300-$500 pixel rate is the best, easy to use, great features.

Thanks,
Ben
