Nology PDA-Dyno

[JasonH]

Anybody have any experience with or know anything about the Nology PDA-Dyno? Seems like it would be a useful tool for tuning, as well as allowing you to reset check engine lights.

I'm thinking about getting one to go with my Mazdaspeed Protege. I know there are some similar kits (software + cables/adapter) out there. Is there one that's better and/or cheaper?

I don't see how simply connecting to your OBDII port will tell you how mcuh horsepower it is putting down...

All the home dynos I have seen require some lead on the ignition wires and some other information.

Looks interesting though.

Well, the cars can give you all their acceleration data from the ECU through the OBDII port (along with RPM and a slew of other info,) the program just does the math. Of course, if you do your runs downhill you'll end up with 400hp or something, so a drag strip is a better place to use it.

Damn, I'm getting a PDA, or if it is more affordable, a laptop. (thumb)

I knew that the OBDII port gives all kinds of info, I didn't think it kept track of acceleration information that could be used to figure horsepower.

Even if it didn't, the program on the PDA could just calculate how long it took to reach 60. About the horse power, you have to enter your car's specs. They have a file with most car's specs as of now. Ours isn't listed on the Nology website. These figures could be dug up though.

I was going to say, acceleration information is kept by a data logger, which OBDII is not. Most data loggers have to have an extenral source that uses some form of measurement to determine the acceleration forces.

Kartboy has a thing that will do that on a pocket PC...The MaxQData Data Aquisition device.

Mark was telling me it was a pretty cool thing. You can even keep track of a track that you are on view it on your pcoket PC. It'll keep track of all the forces on the device which if mounted properly would be pretty much the same for the car, which would allow to see exaclty how fast you went through a specific corner, etc, etc, etc....

What is the math behind horsepower as determined by a 0-60 time?? It would be considerably cheeper to simply time the run yourself, and do the math...And that equation isn't going to be compeltely accurate, as with the 1/4 mile ET and speed equation to determine horsepower isn't accurate.

Right. Not as accurate as the real thing, but better than nothing.(thumb) Worth a look to me...I should have a PDA in a week.

I like the specs on the MaxQData MQ050. Tha main difference between it and the Nology is the built-in accelerometer in the MQ050. The price is higher for the MQ050, and it doesn't come all the cables like th Nology, but I like the fact that it hooks up to a PocketPC (and has the accelerometer.) I don't have a PDA, but if I did buy one, I would prefer the PocketPCs. Everybody save your pennies and get somebody to organize a group buy.

Yeah, I hear ya! I will be getting a PDA (Palm m130) though because if I want a Pocket PC, I will get a Laptop...from Dell. I just want to be able to do quick and dirty data reconasance (sp). Thanks for passing along the info tho! (thumb)
