Now Available: OpenFlash Datalog Viewer and DataZap!

[Shiv@Openflash]

OpenFlash Datalog Viewer

As of this morning, the OpenFlash Tablet is now capable of storing datalog files in it's on-board memory (just plug your OFT into your laptop and run the OpenFlash Manager application with WIFI available and let it auto update). This means that you can record data (up to an hour) and then connect to your laptop (through OpenFlash Manager) and download the data file in .CSV format. The nice thing about .CSV format is that it an be viewed in many popular applications such as Excel, Numbers, etc,. While recording data, you can also view it realtime on the OFT screen in numerical or scrolling graphical format.

But now, the datalog file can also be viewed in our own Datalog Viewing software which is (now available for download from our website)

This is a very useful tool when it comes to confirming that the tune you are running is properly matched to your car's hardware. It also is a valuable tuning tool when it comes to squeezing every last hp out of your car safety. Here's a video tutorial we made a few months back show how easy this is to use:

Please Note: This video was created primarily for our BMW OFT customers but it applies equally to our GT86 OFT customers. The only difference is that the GT86 doesn't have the in-dash boost gauge feature so you can ignore that part (for now)

DataZap

Another extremely popular and very user-friendly datalog analyzing tool was made by one of our long time customers (who will soon join in in this discussion after his account is active). It is called datazap and you can use it by going to www.datazap.me. It's used extensively by BMW customers and now it can be used by our FRS/BRZ customers. It accepts OFT datalog files and allows you to create and share interactive datalog graphs. It's quite spectacular and free (although I hope anyone who likes it will donate something to him considering the amount of work he continues to pour into this online application).

I hope you guys enjoy the direction we are going with OFT functionality. We still have a lot more to do and will have some more exciting news over the next few days!

Cheers,
Shiv

Thanks!

What's up guys! I'm the one who made datazap. I hope you guys like it, I tried to make it as easy as possible to use.

There's a help screen that documents some of the features, but since I've found that no one likes to read those things, I'll explain a few of the things here:

Here's an example data log to play with: http://datazap.me/u/jpsimon/3rd-4th-gear-pull

- Click + drag to zoom in on a portion of the chart

- As you turn on/off sets of data, you'll notice the URL changes. If you want to link someone to your datalog with specific data showing, just copy the full URL once you have whatever data you want to share visible. When the person goes to the link those bits of data will load by default.


- Once uploaded, your datalogs are saved on your main profile page for reference.
- You can re-download the raw .csv from there (or on the chart page itself)
- You can search/filter the data logs list
- You can favorite datalogs and users. Those favorites are seen only by you on your profile page

Coming soon: multi-log upload

Let me know if you guys have any questions/feature requests.

Every day I am further impressed by the quality of work that Vishnu puts out

Thanks to Shiv and Company - I bought the OFT over 2 months ago in September based on the promise of data logging "coming soon" along with the basic tunes that were available at that time. I can say that as of today, I'm 100% satisfied with the OFT, its capabilities, the free tunes, and for support through programs like TunerPro, OF DataLogger and now DataZap! For the price and the flexibility OFT offers, I say 2 thumbs up!

Oh yeah...all that above...not to even mention the upcoming UEL header that will be available soon too!

That's enough .js to kill a horse. Nice!

[jeebus]

I can confirm to all users like me...did a nice long log this morning (45 mins or so). Connected to PC, ran OpenFlash, read and exported log all fine and dandy.

Excellent work!

[krulux]

Ditto jeebus... not 45min but 20min...

OFT data logging works fantastic!!!

Great job Vishnu team!

btw, if you try to upload a 45 minute long log to my site it probably won't work. It's designed for more reasonable logs. The library used to parse and convert the data will timeout on a super massive log.

Yeah, I wouldn't even try something this big for graphing purposes. If your site can't handle logs that big, you might want to incorporate a row count into your program routine that maxes lower so you don't spike your host's cpu and get the ban.

or the ability to load specific portions

45 minute log file
-load 1-5
-load 5-10
-load 10-15
. . . . . . . . .

This is what I was waiting for, well done.

[jamesm]

we use highstock (same library used here, i believe) to render datasets much, much larger than any log file could ever possibly be. the issue must be in your csv parser, probably not well optimized and just tries to parse a whole csv in memory at once, which is quite common. is this an open source project you accept pr's on?

yeah, I've done larger datasets before but not in crappy CSV format that requires extra processing. I'm doing some processing/conversion when you first upload the CSV using a php library to help normalize the different types of CSV's. Then there's some more processing that gets done on the javascript side at runtime. It could definitely be optimized, but it works as well as I initially was hoping for.

This started off as a random project to use for myself, then I said "might as well make it for everyone". I'm going to keep on adding in the little features like multi-log upload and stuff like that in the short term. I'm working on another much bigger project that you guys will love that is taking up a bunch of my time so a complete full optimization-rewrite won't be happening just yet.
