OpenFlash Tablet: new v1.40b maps, new website, new sales, oh my
 

Nice to be back with lots of updates/news!

1) New beta maps (v1.40b)
v1.40b Changes (as per the read me file):
-Added Stage 1 and Stage 2 map support for ZA1JA01N (Asian market) ROM
-Added Stage 1 and Stage 2 map support for new 2014 BRZ/FR-S (ZA1JB00C)
-In USDM E85 ROMs (Stage 2 E85 ZA1JA01C and Stage 2 E85 ZA1JA01D), we now differentiate between cars with Equal Length (EL) and Unequal Length (UEL) headers. The Stage 2 EL E85 tune is renamed (formerly Stage 2 E85) but unchanged from the v1.34 release. However, the Stage 2 UEL E85 tune is new and completely different. It is highly developed and has only been tested in cars with the OpenFlash UEL header. It is considered Beta status and should be used only be those who are sufficiently comfortable with data-logging and analysis.
-Stage 2 EL E85 maps have been approved for use in completely stock vehicles running E85.
-All non-USDM and USDM-ZA1JB00C (2014 BRZ/FR-S) tuned ROMs and considered Beta status.
-Adjusted checksum values so all ROMs can be opened in RomRaider without displaying checksum error.
-Re-enabled diagnostics routines for o2 sensor faults in Stage 2 and Stage 2 E85 maps. If you trigger these faults, it is due to an exhaust leak at your header flanges from not replacing gaskets when you installed your header.

2) Our NEW WEBSITE that is 100% dedicated to the BRZ/FR-S/GT86! It's still in its infancy stage but there is still a lot of new content (new products, new pics, etc,.) There is some holiday sale info and details on our OFT Dollar Discount program. We wanted to make the OFT literally pay for itself so this is what we came up with :)
And by popular demand, we now have an option for those folks who already own a pre-existing locked tunes and want to make the switch to the OFT.

3) We now have OFT maps (pump gas and E85) for the Phantom Electric Supercharger (Dyno Results HERE). Vortech SC maps should be available by early January. Both will be available to our OFT customers by request.

4) Also, we now official support RomRaider for map editing. The RomRaider team has done an excellent job of creating definition files (XMLs) for many different ROM cal IDs. This means more available time for us to work on firmware updates (new features!). Many of the RomRaider XMLs we now have available for download should only be used to edit the ROMs we have available for download. They may or may not work when viewing your original ROM.

I'll be active on this thread for the rest of the day so feel free to ask any questions :)

Cheers

Sweeeeeeeeet, I've been sitting in this subforum all day waiting for this. Anxious to try out the new E85 maps after my track day this weekend, when I can switch to the corn juice again. I also checked out the new site this morning, looking good, keep it up!

Oh, question, have any changes been made to the e85 maps to resolve any of the cold start issues people are having?

Hi Shiv,

I just did a comparison on 1.40B vs 1.34B Stage 2 ROM for ZA1J700G (EU MT) and it seems like the only change is re-enabling of the O2 sensor diagnostic. No other further adjustments made on AFR ?

Correct. The only mapping changes (besides o2 sensor diagnostics) pertain to newly supported ROMs (ZA1JB00C and ZA1JA01N) and USDM (ZA1JA01C and ZA1JA01D) Stage 2 UEL E85 tunes. International ROMs are unchanged. But now there is RomRaider support for map editing.

I'm confused, are the new el and uel tunes for e85 only or is their a uel tune for pump gas. Also, what are the gain differences.

I will test the tune with my borla uel headers and post the datalog results here.

There is no change to cold start values in the E85 maps. We haven't run into cold start issues in our test car so it's hard to us to make any prudent changes. It seems our E85 source is providing a winter blend unlike some of the other E85 sources which have reported to still run a summer blend with high E% content. Hopefully there are those who can make successful cold start mapping changes and let me know what works for them so I can apply it to the OTS maps in the next release.

Hi Shiv,

Thanks for the prompt reply. I was hoping for some revisions on the AFR as I've done some WOT logging on 1.34B and AFR was showing like 11+, which was a bit too rich imo. I wonder if this should be the correct AFR expected for stage 2 ROM ?

It's hard for me to do revisions on international cars/fuel that I don't have access to. We can do some e-tuning support if that is something that you are interested. If so, email me at shiv@vishnutuning.com. It takes some time to dial it in correctly but it's a good option if you are comfortable with making the changes yourself or don't have a local tuner who can do it for you.

Cheers

"3) We now have OFT maps (pump gas and E85) for the Phantom Electric Supercharger (Dyno Results HERE). Vortech SC maps should be available by early January. Both will be available to our OFT customers by request. "

I bet Vortech SC and Phantom Esc sales will skyrocket!! Shiv pls make a OFT Tune for the Avo Turbo. My F1 choice next year....

The new EL and UEL tunes are for E85 tunes only. We will differentiate between EL and UEL on gasoline tunes soon once we go back to running gasoline in our test car.

The differences between the two tunes (and two headers) can be seen here:

http://i85.photobucket.com/albums/k4...06/UELvsEL.jpg
Runs 174 and 174 OpenFlash Header with OFT Stage 2 UEL E85 tune
Runs 151 and 152 EL header with with OFT Stagr 2 EL 85 tune

Summary: OFH with OFT UEL tune made more top end power and had less torque dip
Note: Vehicle was also equipped with Perrin drop in filter and modified (shortened) air duct

Hi Shiv,

I just sent u an email with logging attached (via datazap) for you to take a look. Most probably I'll need e-tuning support from your end.

what is oft dollar i couldn't see any description about it.

What is the procedure for getting one of the OFT generic base tunes corrected for a particular setup? I understand that these base tunes should be in the ball park but obviously they need to be fine-tuned for different setups. Is this supposed to be Shiv or the end-user? What does it cost for each remote tune update from Shiv?

nice work on everything! still loving the corn tune...just wish i didn't have to fill up so damn often :P

From the website :)

are you selling now e-tuning as well with the OFT?
because that would be a big step.

While the OFT maps are open and editable by anyone, we can certain do remote e-tuning if that is what makes you most comfortable. The cost of the job depends on the complexity and is determined on a case by case basis. If you're interested, email me at shiv@vishnutuning.com. Mind you, this service is limited to those who have setups that we have already tuned (so far just NA and light pressure SC kits). We don't expect to do e-tuning high boost turbo kits anytime soon.

Anything for the Innovate SC in the near future?

Shiv,

when comparing the new UEL E85 maps to the old E85 maps it appears you've changed the MAF sensor scaling? Is this intentional?

Yes indeed. There are a lot of changes made in the UEL map (closed loop fueling, VVT, ignition timing, open loop fuel, etc,.) and they are all intentional :)

The UEL E85 Stage 2 map is probably the most developed map we have ever released. I started developing it 4 weeks ago when I installed the production version of the OpenFlash header. And it's been tested/tweaked every day. It was only last week that I stopped fine tuning and and have been tested long term stability. And it's been pretty great so far. Looking to see more customer data logs :)

OK, just making sure before I flash it. I'll take logs tonight and tomorrow with my borla UEL and hopefully everything will work out fine. Its been dipping down to the mid and high 20's at night so I've been dealing with nasty cold start issues, but I've got them down to one or two cranking attempts with some help from the romraider crew. This is why I love open tunes instead of the other options that are locked down, I can get help from lots of places to fix my own issues. ;)

Do those of us who purchased an OFT early still get OFT dollars credited to our account?

Of course! Just as long as we have you in our customer records as an OFT buyer, you get the same OFT dollar discounts :cheers:

That's great to hear. If you let me know what your cold start settings are, I can test them myself and perhaps integrated them into the OTS maps for everyone else :)

Might have to try me a tank of E85 with my new EL header. Couldn't run it all the time it would be a hassle running across town to get. Another nice thing about OFT, having the ability to swap on the fly when I want.

I am intrested in e-tuning. Just sent you an email.

Ok. We should have the options for custom e-tuning on the website either tomorrow or day after.

I cannot exaggerate this enough when I say "YOU SIR ROCK!!!"

Thank you for the continuing support and work on this car!!!

Maybe if someone or a group of overseas individuals want maps maybe a group could pay for you to fly out there for a week and put you up in a hotel.... You never know it could happen lol. At least that way you would have access to their gas.

Ok, flashed the Stage 2 UEL E85 maps. Went out for a 10 minute drive to meet up with some friends. Car sat for ~1.5 hours. Got back in the car and started logging ~3 minutes into the ride home.

Looks like I haven't had the maps flashed long enough for the LTFT to settle down, but first impressions are that the engine sounds different for sure. The wife couldn't notice it, but I could. Mid range feels a tad smoother but my butt dyno isn't adjusted enough to read any gains on the top end. Like the other E85 logs I've taken, the AFR likes to go rich towards the 7k+ range sitting around 11.9ish. Not sure if thats normal or not.

Thoughts Shiv on these logs. I'll take some more tomorrow morning when I head out again.

As for the cold start tables, I'm going to play with them a bit more. I think I'm heading in the wrong direction with the cranking pulse widths and I want to try and adjusting them down from where I had them a bit to see if that helps. Logging should help get accurate readings instead of using a weird metric like "cranking attempts".

wow just wow! improvement every time!! i love my stage 1 map! I am also glad there is support for ESC!!!

Just flashed the car, sounds normal and the revving is great off the bat -- another success for 1.40b!

please share where you are pumping your e85 at for us locals.

How many OFT dollars can you use on your next purchase if you can't use them all at once?

Better question is how do we access the oft dollars for the early adopters of oft :iono:

Shiv commented that if you chose the OFT dollar pricing option, they would email you. Since they keep track of who bought them I'm guessing that's how you make use of it. Knowing that, I'm going to have a hard time not grabbing that perrin intake or that painted rear spoiler.

If you go through to the end it doesn't have any other option but to pay w paypal or credit card :iono:

Are there any changes to the Stage 1 (non-header non-e85) tunes from 1.34? The description in the OP doesn't make any mention about the Stage 1 tune. Basically, would there be any benefit for me to flash to 1.40b? If not, I'll just stick to 1.34

Same question..thought it seems that there aren't any changes if I'm interpreting correctly.

No changes to the Stage 1 tunes AFAIK. Only small changes to the Stage 2 tunes (o2 codes re-enabled) and new tunes for UEL E85 Stage 2 and new ROM support (china market and 2014 USDM BRZ/FRS) :)
