Data Logging
zilspeed - 4/9/10 at 04:52 PM

Anyone out there run any form of data logging ?

We're interested in investigating what's available for various projects which are ongoing and would be interested to hear the views of anyone who has used it, be it home brewed or off the shelf.

Being renowned as being a wee bit tight, I'm obviously more interested in a home brewed solution.

What's available ?
What software do you use to analyse the results ?
How much does it cost ?

Cheers

Hi
Im also very interested to hear the responses on this thread. So far at the cheaper end of the scale, i've only found etb and race tech but they are far from cheap...

Is this to measure rebuild time John...(he! he!)

Nah.

A ten year calendar will do for that.
Yah barsteward.

Any roads, I did more today.
If a job's worth doing, it's worth doing slowly and badly.

No, this is for an associate.

The Race Technology DL1 seems pretty comprehensive.

I bought a digidash which has logging for the fury, it has plenty of channels, logs at a reasonable rate, and the analysis software is pretty decent, it does mapping and can do some video overlay too.

For the locost i rolled my own, the plan is to use a tomtom to do the logging itself, but for now I use a laptop until i've got the rest of the software working right. It uses a bunch of USB sensor dongles to pull analog data, and a serial dongle connected to megasquirt to dump out engine metrics.

Visualization i'm using a combination of excel and paraview.

Are you talking about logging engine data or car movement data?
If the latter then try racechrono.com and you will need a GPS enabled phone (nokia or windows based IIRC)

If the former, then the etb digidash at £400 would be ideal. and you wont get much cheaper than that i doubt.

veypor does the datalogging of car movement for quite cheap. Uses accelerometers.

In repsonse to the last couple of posts, it's pretty much all of it.
Accelerometer to measure braking effect.
analog input to measure brake line pressure to tie in with the above.
This would be an example of the type of thing we're interested in.

engine data will be based on a carbed engine with a dizzy, so fairly limited.

GPS for track position, we're not so sure about at this point.

It's really about being able to analyse what the car is capable of doing and then assessing how the driver is putting that capability to use.

Thanks for the input so far.
