Nology PDA Dyno, here I come!

[LinuxRacr]

It does not mention an accelerometer in the Nology description. It may be getting its information purely from the OBD-II port. You can get speed and then integrate this to get acceleration. Then with the weight of the vehicle, determine the HP. The environmental values will scale this to a sea level normal day. The Cd is used to further increase the rated HP by absorbing the HP loss due to drag. Rolling resistance is probably figured in as well.

Wow, that thing sounds kool, and to think it works with Pocket PC! I just wanted to point out that with the PDA Dyno, you can change the elevation, and environmental variables. What has been your experirence with the MQ 100?

Further, with the upgraded version, GPS track mapping can be generated, then compared with the G-Path. You can also add your own sensors, such as steering input, brake pedal force, etc., much more of a professional DAQ system.

Mark, how difficult is it to add steering, brake and throttle position sensors to the MaxQData system? How difficult is it to use the sensors with the software provided? It could be really interesting to have that kind of data for autocrossing.

I'm not sold on the GPS thing (for autocrossing and tuning) but I guess it would be more useful in full-on racing like USTCC.

Do both of these systems have high enough refresh rates that the display can be used as auxiliary gauges, ie. instead of installing oil pressure, voltage and boost gauge, just display the data from the OBDII?

The only thing environmental variables do is to scale your HP and/or 1/4 mile times to Sea Level. This can be done on the MaxQData system as well, but is not currently included. I really see no great value in road horsepower calculations since there are so many factors involved. A chassis dyno, or better yet, an engine dyno is the only good way to make comparative evaluations of mods to your car. Of course, they don't come cheap.

The value in the MaxQData system is in the ability to collect useful data on the race track. With GPS track mapping, you can overlay a map of the track to quickly scoll to a selected portion of the course, and look at your braking Gs to see if you are consistent with your braking points and holding max braking without lockup. Lateral Gs will help you determine your chassis setup and help you tune that and/or your ability to control the car. With the various OBD-II outputs, you can check rough numbers at 2 second intervals. With a external sensor on the MQ100, you can record at 60Hz (60 times/sec), so this would be the best to monitor dynamic values. Water temps, oil temps are probably ok with 2 sec samples, but RPM and throttle position are better recorded at higher freqency.

We have had great luck with the system, getting the drivers to use it when I'm not around is a little more difficult, but not impossible. You have to be dedicated to really maximize the value of the system, and not just use it to plot cool pix.

Drivers would have to be written for your particular steering input sensor, which would likely be a sting pot wrapped around the steering column.

The GPS is valuable for autocross, but not necessary. The two way accelerometer certainly is, and with the generated G-Path, you can tell where you are on the track, but it won't look as realistic.

Cruzer here on the board is using the MQ050 for autocrossing, and would probably tell you about his experience.

I mentioned the gauges above. For the most part, yes either system is pretty good and a more versatile vs gauges which would take some time to install. The MaxQData system only shows 2 sensors at a time in real-time display.

You can download both the PocketPC and Desktop versions of the MaxQData Software for free, as well as some sample track data. Obviously, without the hardware, you cannot record.

hey, i'd like to bring this up again, but is there a program out there that you can run on a palm or whatever that allows you to "update" the ecu? ie tell it to run leaner/richer, advance ignition etc????

later

 

[mark@kartboy]

The MaxQData unit will allow you to view and reset check engine light codes, but not change any parameters. Unfortunately, this normally requires an EPROM burner, to either burn a new chip and replace the old one, or a newer style system where you can flash the stock one to a new configuation. This is best left to the pros, since you can screw stuff up very quickly.

Bump, bump, bump!

Patrick,

I just ordered the PDA dyno. E-mail me the parameters I need to input. Thanks!

 

[JustMe]

Does that thing works only on pocket PC or can I install it on laptop and get all the info from the obd2?

 

[LinuxRacr]

Not for PC's. The only PC intervention here is the install, and hotsyncing of data. Oh yeah, and spreadsheet conversion of data.

Help is on tha waaaaaaaaaaaaaaaay!!!

 

[stepson]

Linux,
does anyone live near you with a Mazdaspeed that you could try to plug this thing into and see if you get data? I'd like to get one, but I read the ECU is ford, which these palm ODB2 loggers don't seem to like ... maybe a friendly dealership?

 

[boostisgood]

Linux, what did you pay for this, and where did you order it ? I am considering getting this, as timing can actually be monitored with it, along with just about everything else.

Here you go, I have one also. Great tool!

 

[twilightprotege]

while this subject is back, i assume there is a similar program for a laptop...does anyone know of one????

[dficken]

Does that PC software do dyno stuff too?
It didn't seem like it.
If not, know of any PC dyno software?

Thanks.
Dale.

 

[YP5 Toronto]

agreed...the autotap software didnt look like it gave out Dyno numbers.

plus $199 USD is quite an investment.... anyone else have any PC software links.... or even better Pocket PC links?
