Evoscan log script
Here's a short little matlab script that folks might find useful for looking at their EvoScan logs. I whipped it up this morning to look at the log of the drive to work, but other people might be able to use it for more interesting things. It'll generate a bunch of nice plots for you and it makes it really easy to generate statistics.

Anyway, enjoy.

Soon we'll have to make a sourceforge for the open source logger and other related tools..

Yeah. I've been thinking about that. The my library of useful and semi-useful car logging functions has grown seriously large. They should all be collected and posted. I have code to do so many different things that an application doesn't seem feasible, but I bet I could squeeze them into a library or framework or something.

I think its great people are making and sharing tools like these. I really loved the log viewing program Second Chance made for EVOScan v.7. Unfortunatly it doesn't work with the v.8. Currently I'm using datalog lab, and maybe I'm not using the software to its full potential but I think it's just "OK". Not really worth paying for IMO. Anyway my free registration expires in 19 days so I hope there is an alternative by then.

Python!
Seriously though, as long as it isn't Java or ThesePeopleShouldLearnTypeTheory.Net then I can probably port my stuff over to it. A very small section my data analysis code in pyxede is in C and I doubt that many other languages would provide sufficient performance (realtime noise filtering).

Don't get me wrong, the power graph & scatter graph are 'neat' functions but I personally just don't see those two options as making it worth paying for. Like I said above, maybe I'm not using the tool to its full potential...

The advantage of using a really powerful tool like matlab is that it's super easy to look at the data in new ways as you think of the.
For example, maybe knock vs. tps isn't that helpful because data is clustered in a band. How about knock variance vs. tps variance.
plot(variance(knock_count), variance(tps), "My title");
like magic.
