Tesla Roadster Data Logging Format Reverse Engineered

s1axter writes with word that "the data log format for the Tesla Roadster has been reverse engineered and documented, now available in Python. (Python script linked in the post.)" From the linked blog entry: "Not only was I given a $110k car unrestricted I was requested to see what ECU information is available, collect and parse the data from it. Tesla Motors periodically collects information from their vehicles presumably to see what real-world driving the cars see. On original Roadster models there is no method to collect this information remotely thus someone must go out to the vehicle and collect it. The owner of the vehicle saw this and wanted to know what information was collected on these service calls ... Because I am a big fan of freedom to modify a program to fit ones needs, I have uploaded the ... python script to parse Tesla logs."

The rev limiter is there precisely so you don't hurt anything, once a year would be ridiculous. What it can't stop is people with a manual transmission shifting to a lower gear when the RPMs are too high, which will create an unavoidable over-rev situation.

But it's a wicked fast pile of duck shit...

Not really. Its top speed is a "mere" 125 mph, something my 33 year old Porsche can (or could, when new) beat.

As far as acceleration goes, though...yeah, it's very zippy.

Please move along ... nothing to see

All he is doing is bragging about a python script that he himself admits to be simplistic and ugly. The binary format was decoded by two other posters in a bulletin board who also wrote a windows parser but the original guys did not think it warrants any kind of bragging like this. And he is not posting the logs either due to privacy concerns. So unless you are curious about seeing someone's ugly hack of a python script, just move along, there is nothing to see here.

Isn't that statement redundant? All python code is simplistic and ugly.

That's true of any very high-level language, like Python, Ruby, Haskell, Pascal or C.

Slashdot requires you to wait between each successful posting of a comment to allow everyone a fair chance at posting a comment.

It's been 1 minute since you last successfully posted a comment

Dear slashdot janitors,

Between your stupid "It's been 20 seconds since you hit reply", the entirely unusable new comments system, the "new" user pages and this seemingly random delay before you can reply to another post, you are slowly making your site harder and harder to enjoy using. Do you really want to drive readers and commenters away? Please fix the broken stuff, before adding cheesy-looking "lightbox" popups for logins and other such pointless crap.

Thanks,

Gordon

Most places you want to drive, top speeds are greater than speed limits so acceleration is more significant.

Yes, pushing harder will get it in gear, but at the expense of shortening your synchros life - much better for the transmission to hold off on ramming it into first until you're slow enough that it slides in easily. Or just leave it in neutral, let the clutch out and use your brakes. When you're ready to go again, just shift into first.

Remember: brakes are almost always cheaper than a clutch or a transmission rebuild.
