Now Available: OpenFlash Tablet Datalogging/Datagraphing (BETA Release)
 

Hi guys,
While we still have a few bugs to work out and some changes to make, I wanted to get our customers something to play with in time for the weekend. Of course, this is a free update. To get it, just connect your OpenFlash Tablet to the OpenFlash Manager software and make sure your laptop has WIFI connectivity. And then just let it auto update (takes 30 second or so). After your your OFT updates, you should have access to these new features as shown in the video link below.

Video posted on our Facebook Page.

Please keep in mind that this is a very early BETA release. There are a few known bugs that we will resolve next week. Such as:

1) VVT Intake logging is not functional. It just reads 0 for now.
2) Advance Multiplier is not logged yet. Just need to work out the scaling. But it will be added just below LT Fuel Trim.
3) Throttle Act will be renamed Throttle Angle. And currently it logs idle motor duty cycle, not actual throttle angle (:lol:)
4) Datalogging to CSV file doesn't work just yet. So you won't actually be able to save a datalog yet. So this is mainly for viewing purposes right now.

Also, after these bugs are fixed, we will start working on an update that will allow you to have access to many more channels (but only 12 can be viewed/logged at the same time). There are still many more channels that are useful for tuning purposes (Engine Load g/rev, MAF voltage, Knock Correction, Manifold Pressure, etc,.) We also have some ideas on adding an menu option for displaying stylized digital dash/gauges. We will also be adding a screen showing the fine learning matrix.

Once again, this is an EARLY RELEASE so please be patient with regards to any issues. They will be resolved early next week.

Cheers,
Shiv

PS. OpenFlash Tablets are now back in stock :D

Great work. keep them coming.

:happyanim::happyanim::happyanim:

Awesome! :thumbsup:

you gotta give credit to shiv, seems to be working on improving and developing this at a mad mans rate, holy cow this kinda progress might make me consider OF over ECU Tek.... very cool!

I'm close to finally buying a tune and OFT has clawed its way up the list to numero uno. Very cool updates man.

Ha, I put in an order just about 15 minutes before this was posted. Great timing! Can't wait to get it delivered!

any word on when the oft will be shipping? still waiting for mine.

We are getting units programmed right now. Hopefully we can get all pending orders out today. But we will be limited by UPS pick up time. Any order not shipped out today will definitely ship out on Monday. Sorry for the wait. Last weeks SEMA show slowed the entire manufacturing/shipping process down :(

Shiv

sounds good, Shiv! Looking forward to receiving mine once you've done all the due dilligance, no rush just was curious.

If someone in California wanted to physically pick-up a tablet from you guys, (when they are available) do you mind that? I only ask because I am in San Jose and picking one up rather than having it shipped kinda makes more sense, but then again I don't mind if it has to be shipped - just curious. thanks.

Sure. That's not a problem. Many locals come pick up from us directly since we offer an courtesy install if time permits. We will also be at the Dublin meet tonight if you wanted to pick one up and get it installed :)

Cheers,
shiv

I'm so excited!!!!

Ok I know this may be a stupid question but I plugged in the OFT and opened my Flash Manager but I may have missed the device auto update.

With that, what should the most recent Hardware and Firmware version be?

Firmware # hasn't changed with this datalogging update. It will still be #117. Hardware will always remain unchanged (until a hardware revision I suppose) at #100. You can confirm that your OFT has been updated by just going Diagnostics->My Car-> Realtime Data Display (as shown in the video on our FB page).

Shiv

Oddly when I open OpenFlash its saying my FW version is 1.16 but the actual tablet says 117. Its also still stuck in Italian. Am I having issues or is it the same for everyone.

oh heh, i just read export doesn't work yet. I was like "why is this still sitting here not responding"

Oh well...it can wait. Keep up the good work!

Immediately after the firmware update, the Openflash Manager software won't reflect the new FW version version until you quit and launch it again. But your OFT will show it immediately after the update since it automatically reboots itself after the update. But as stated before, this mornings datalogging update won't increment the fw number. It will still be #117 as it has been for a little while.

And yes, the ECU info section is still written in Italian. There is a new update coming out which will provide the ability to store more than 2 maps in the OFT. The language bug will be sorted out then since it's not really an urgent fix at this time.

Shiv

Ok I figured out my issue. I was still running Flash Manager 1.02 and it didn't seem to want to update when connected. I had to install Flash Manager 1.03 remove the OFT from the computer reconnect it and reopen the Flash Manager. After I did that the OFT updated and I now show FW Ver:117 and it appears to have finished updating everything.

Here's some fun stuff from the OFT's new datagraphics function:

This is an OFT screen capture of 3rd gear pull (2000 to 75000rpm) running the new E85 map:
http://i85.photobucket.com/albums/k4.../photo2-41.jpg

Green is Engine Speed (RPM)
White is Ignition Advance (Deg)
Blue is MAF (g/sec)
Purple is Air/Fuel Ratio

You can see that MAF looks just like the hp curve with the torque bump at 4500rpm and peak hp at 7000rpm. Timing advance ramps up from low rpm and fills in the relative dips in MAF nicely. And AFR is stable at 12.5-12.8:1 through through the entire rev range with the leanest spot right after the post dip torque recovery. Those who live on the dyno will find all this stuff very familiar :)

Shiv

The anticipation of these E85 maps is killing me! Got my tank sitting almost empty waiting for the maps.. Had to put in two gallons this afternoon so I can wait another day ;)

That logging looks very nice. I noticed that the option for 8 months of remote tuning support is gone from your website. Is that gone forever or just until you can catch up on all those remote tunes?

We do need to catch up a bit. And before we reopen the flood gates, I'd like to see some new OFT updates in place to make the process more convenient for the end user.

That's funny, I've been doing the same thing all week.I had to put 4 gallons in today so I can make it through this weekend's autocross. I have all the e85 stations mapped out and http://procedetuning.com/BRZ_FR-S/do...s-4/index.html bookmarked for immediate download. It's kind of sad now that I think about it!

Just in time for me to be able to show off at the AZ86 Bash this weekend, so far over 100 have RSVP'd to join us there!

Thanks Shiv with this and E85 completed your OFT will become the choice of many on this forum as the standard I'm sure!

Possible black friday specials on the OFT???? =D

should be easier then me data logging thru techstream lol

Here's the sneak peek of new screen graphics we are working on:

I really like where this is heading. I hope everything is ready for FI come March when I go SC.

Looks great! Would be nice if it were a WRB in background ;)

@shiv@vishnu

Ordered my OFT today. Sent an email to sales to check stock and see about faster shipping options. Really excited to see where you guys take this product. Do you think at some point we could create some sort of index thread? Like a thread that links to all the other / new threads? It's a pain to keep track of all the different ones.

If you sent an email to sales@vishnutuning.com, you should hear back from them tomorrow. They should be able to overnight it to you so you have it on Tuesday :) As for the thread management, I'm actively trying to consolidate thread topics at this time. Thanks for the order!

Hi Shiv!

Thank you for entertaining us with that diagnostic feature.
In accordance with my results, my average AFR Bank 1 rate is 14.58-14.70
running stage 1 with drop in filter and snorkel cut. Does it seem lean mixture or is it standard number? And please explain what is "KC learned" gauge showing me? Is it knock correction? And what should this gauge show when engine running in good/safe mode? I always see KC learned rising upto 4-4.5 when stepping on the accelerator pedal. Gas is 98 octane (equal to 93 US AKI)
Sorry for the noob questions, i am totally new to the tuning of this kind.
Will be much obliged is someone explains me what should i do - to relax or fix something?
Cheers,

Andrey

i can try to help with some of this. your afr should hover around 14.7:1 when you're in closed loop just cruising around, so that's probably fine. it's very rare that you'll actually see a fueling error bad enough to cause the closed loop afr to not hit target (that's what trims are for).

i'm guessing that 'KC Learned' is the knock correction learn value, which if positive is good, meaning that the ecu's knock correction is adding timing, not pulling it. there is however much, much more to the subaru knock control strategy than just that one number. i can log positive kclv while simultaneously pulling timing in either of the other two correction modes (kc and flkc).

to really see the 'whole picture' on knock control you need to look at the iam (it should be 1, always, if not you are in 'coarse correction' mode pulling timing across the board and something is wrong), flkc (they should be close to zero in every cell, though a -1 here or there isn't terrible), fbkc and the aforementioned kclv.

basically the IAM is coarse correction, the 'nuclear option', it pulls timing out of the advance map across the board, as a percentage (where total timing = base timing + (iam * advance) + corrections + compensations). flkc is 'fine learning knock correction'. this is broken into load/rpm cells and is applied over time, but this mode is only entered when load is relatively stable (not changing quickly). you'll never see positive values in flkc unless your iam is less than 1, which means something is already wrong, so only expect small negative values here if any. fbkc is 'feedback knock correction', or instantaneous corrections applied from feedback from the knock sensor. this is the 'default' operating mode for knock correction when conditions aren't met for one of the other modes.

that's just my relatively limited understanding of how it works, i could be missing bits and pieces.

Great! :thanks:
Thank you so much - your kind explanation is much much more than i knew about all those correction features/principles by now. The German cars i owned last 15 years didnot require any tunes as they had quite enough of NA power,
but with this one i have to start to learn new tricks (and more specific English words and abbreviations), what is a bit difficult way for the old dog...

Thank you again, man!
:respekt:

I know this is probably a silly question, but I didn't see it listed in the picture, and I didn't see any mention of it.

Will it be possible to monitor engine oil temps using the OFT? I know this may not be that important to some, and I do have Torque Pro if not, but I like to be able to know when I can switch from babying the car to getting on the gas. It would also be useful to monitor the oil temps on track days for those that track their cars (which I plan on starting in the Spring).

Not a silly questions at all. In the near future we will expand logging options so that the user can chose (from a much larger list) to monitor up to 13 channels at a time. This will mean scrolling through a list of available channels and choosing which ones you want to make active. Oil temp will certainly be one of them.

Cheers,
Shiv

Whoa, what is this pink description at the bottom of your signature Shiv? It reads " open flash for UEL header" u already have a stage 2 designed for catless headers. Please elaborate

I think what it means is he's going to be releasing his own UEL header ;)

It sounds like a Vishnu tuning header.

We have been working on a header for some time now. Makes sense since we have tested so many of them on the dyno (on the same car). It's performing well and I think everyone will be happy with the price point once it's ready to ship. Can't say much more than that at this time :)
