Tatrix + Header tuning solutions
 

Correct me if I'm wrong but if you are a tatrix/ecuflash owner there really aren't any header basemaps or even independent tuners who work with the tatrix?


Its really a DIY proposition, which I'm ok with but time is money and if anyone knows of a dyno tuner in the mid atlantic to NYC who will work with a tatrix I would appreciate it.


On another note if I wanted an Innovate why wouldn't the CARB package come with an unlocked basemap?


I'm just looking at possible upgrade scenarios for my new toy.






Paying 25% the price of a blower for cables and flashing licensing seems counterproductive for both Innovate and the customer.


The Tatrix works great for flashing roms to the ECU why aren't more using it like the rest of Subieworld?

Sounds like you should've done your research and gone for the OFT.

Quick answers to your questions:

- Header basemaps - Shiv's OFT ones will do nicely.

- Tuning solution - use Romraider. Any Subaru tuner should be able to use that.

-- CARB tunes are not unlocked as essentially they can't be AFAIK. To stay emissions compliant nothing can be changed, or it would no longer be the CARB tune would it?

- Why is no-one using it yet? Well I'd assume that its still early doors on this platform. Most would be scared off by a beta software status. When things are finally nailed down it will pick up. Lots of people would love a pick up and go solution and don't have the know how to unbrick an ECU should the worst happen. I've noticed that most of the people using it on here have previous Subaru experience and are working hard to bring it to a good end product that can be used by anyone.

Why? I can't see any real difference.

As per your reply.

I did research it to death, I used to tune cars over a decade ago and a pendant flasing device just sort of gets in the way. If you've ever been on a dyno tuning every minute is precious and having the laptop all-in-one is a huge advantage.

I didn't know he was posting those as bins or hex?

Yes but there aren't many locally well versed in D4-S/DI.


Yes a meant locked. It would ensure the CARB integrity, I think RomRaider has a lock feature? I guess what I am saying is not offering a basemap flasheable by the Tatrix or OFT Innovate, Vortech, Greddy, anyone selling an entry level kit is hurting their sales by requiring an expensive SOA cable/license.



And this is sort of what I'm banking on. Almost 2 years ago I had a list of recommended "top" subbie tuners and almost all of them said they aren't interested in the BRZ until tatrix/romraider works with it. But I haven't seen the pendulum swing quite as fast as I had hoped. Probably too much WRX/STi business. I hope we don't end up the red-headed step child of performance Subaru's.


Thanks

It all depends what you want , haltech ecutek tantric cables whatever, you need a tuner unless you really know what your doing

I love to drive wrench and track but I would be a fool to think I have the know how to setup my fi car for track right without blowing it up.

Know your skill set, and yes choose a tuner not a solution if you ask me

You can use any unlocked, unencrypted rom with ecuflash and a tactrix cable. This includes the oft OTS maps that are posted in bin format. Regardless, you're much better off getting a bespoke tune. But yes functionally oft and a tactrix cable are pretty much identical, only the oft has a screen/some flash memory to store maps and the tactrix cable flashes way faster. They both work, it just depends on what you want. Neither hold a candle to ecutek in terms of power and flexibility, but they're both a bit cheaper (tactrix being ~$180 total, so a lot cheaper but with zero support when something goes wrong). Were lucky to have so many options...

Y? what does OFT do that Tactrix doesn't? Pricewise it costs less though and gives an option for those who want to switch to BrzEdit
@regal
if you do decide to use Shiv's tunes you should log and check if it knocks on cruising. For many it does. Then you should revise it and pull some timing off. You can follow steve99's thread on pulling timing off: http://www.ft86club.com/forums/showthread.php?t=61820

1) realtime data displays (numerical, graphic and multi-channel)
2) not require the use of a laptop
3) multiple map storage
4) customer support
5) allows user to get wholesale pricing on other parts (headers, exhaust, power blocks, supercharger, etc)
.. Among other things in the works

The purchase of OFTs allow allows us to continue developing and releasing free unencrypted maps for entire community to use :)

In the end it gets down to support and knowledge level and what you as an individual are confident with.

How must are you willing to sacrifice to save cost
How much is your time worth, do you want to learn or just pay someone to do it.
How mush risk are you willing to take

ect

Tactrix/Ecuflash
- is do it yourself very little support
- maybe some guy on a forum can help
-no tunes (by that platform)
- Very few people possess the skills time and dyno to develop a tune from scratch.

Open flash Tablet

- Comes with tune's suited to variety of bolt on mods plus vortex supercharger and Electric supercharger ect

- Has support and backup- for when flash fails , tune not working correctly , you just want to ask a question, my ROM not supported. My car now doing weird stuff ect , will my mods work with this tune ect, does this look ok.

I have both devices , I always like a backup plan if something unexpected happens

Then you Have ECUTEK and dedicated tuners and specific tunes for your car.

Even further MOTEC HYDRA + tuners ect

+1000

If those maps did not exist , all 99% of tactrix users (non-tuners) could do would be update their ROM to the latest Stock ROM calibration.

Judging by everything you've said about tuning, it appears you just don't know what you are on about.
Be thankful there are OTS tunes by shiv, otherwise you are SOL since you have no means to do it yourself, thus the original comment about using OFT for your usage type as well as supporting him in doing so.

I've got nothing against shive I jutst prefer to use a laptop to flash, when you are paying for dyno time every second count an extra step of going thru a pendant has to slow you down. That's all.




I bought the tatrix soley to update factory calibrations, if it turns into a tuning tool great if not its no big deal.

you're comparing flashing mechanisms, not tuning solutions. for either openflash or ecuflash, you use the same tuning workflow. there is no difference whatsoever, as it's literally the exact same software just a different delivery mechanism.

i think that as it stands now if you're choosing between oft and a tactrix/ecuflash setup, the oft is going to be the winner for most people. the customer support alone is worth the extra money (being that it's entirely non-existent with ecuflash, and bad things do happen sometimes). ecuflash is better for the more technically-minded people who want to learn more about how these things work and don't mind working at a lower level of abstraction. it's for the nerds among us, basically.

so think of it like oft is to osx as a tactrix cable is to #! or some other minimalist linux distro. but at the end of the day they both do the same job. they get a rom from romraider to your car.

For now I just needed the updated factory tune. I've talked to a few professional tuners who don't want or need a pendant stop. I'll check this thread in 18 months when warranty wears out by then there should be some tatrix dyno tuners. If not, my money will probably go to an Innovate with Delicious tune.


We all have our preferences and switching back and forth between computer and pendant while paying for expensive dyno time seems very cumbersome, probably why with the OFT the only tunes available are by shive. JMHO.

How about tuning it yourself and then contribute to the community with your learnings?

If warranty is your thing, you've just contradicted the whole purpose of opening this thread.

In any case, I'll never put a locked tune on my car.

Correct me if i am wrong but I have never seen or heard of any professional tuner releasing tunes for basicly free for any car before .

The realtime data display is supported by romraider, not all params yet and not in fast mode 23 but it's in development.

true, some people though prefer a laptop. Also for logging you just need a cable head and I'm not 100% sure but it seems the logging rate with tactrix is faster which allows to log a lot more params.

Map storage is convenient, but it's not like ecutek on a fly map switching. with tactrix people are using a laptop anyway and flashing with tactrix is faster.

The rest is definitely beneficial for people.

also, more is coming form open source, such as merpmod will be available for BRZ (per Td-d: "cel flash on knock, cel flash on high EGT (using o2 sensor resistance), speed density with MAF blending, FFS with per gear thresholds, LC, per gear boost control. I'm sure I'm forgetting stuff...")

I though bought an EcuTek for that dyno tune from a pro tuner.

Flex fuel is already in beta as well, map switching, per gear boost control. If I had the time to get my head around HEW, I'd make a point of porting this across ;)

It really comes down to how much hand holding you need (not meant facetiously at all) , or how much (or little) time you have - it's a preference really. Personally, I like the flexibility and power of not having to wait for new stuff to be found - but I'm not exactly the median in terms of users. Also, I don't tune others' cars, if I did I understand how the time vs. money equation would be more important.

Horses for courses.

just curious, is it a c code or c++?

C++ I believe.

The Tatrix cable paid for itself already in allowing me to update to the 2014 calibration (dealers refused.) I was just wondering if professionals use it, guess not no big deal.

Um yeah, it is a flashing device.

I'm in the process of converting my ROM to the new B01C ROM base..... Man what a PITA. Spent an hour last night and I might be at the halfpoint.....

What do you do if you find maps that aren't the same between the factory ROMs but is already altered in your tune?

Unless it is something specifically known as an issue (transient retard tables), you just copy your current tune tables over.

So to give you a little background, the reason I am converting it is because the purpose of this updated stock flash is to remove idle dips, specially with AC on. My injectors currently are tuned perfect. I have a very slight idle dip with AC on (it is better than when the car was stock, my current problem is since James teached me how to tuned them and I tuned these ones, your senses are extremely enhanced to any misbehavior the car does).

I have let other people drive the car to see if they see anything wrong and they are all amazed at how incredible it drives.... Long story short, there are several idle control tables not defined in Ecutek yet, so I am going with the new ROM calibration base in hope to eliminate that 0.001% improvement to be had, meaning Subaru/Toyota introduced improvements in those undefined tables... It may not work but was worth giving a shot. If it doesn't change a thing, I'm ok with it. I am extremely happy to have been able to calibrate my injectors like they are right now. It honestly drives way better than stock.

Sounds like a good idea, always good to learn things so we are able to do it ourselves.

All thanks to @jamesm. I have been wanting all my life to know anything about tuning, and he has been incredible. Willingness to help out and share the knowledge is unparalleled.

It's the software developer in me. We teach people things and spread knowledge. Imagine if the software industry operated like the tuning industry does, meaning zero sharing and everyone being protective of what they incorrectly view as proprietary knowledge. We'd still be reinventing the wheel every time we needed some basic, common functionality. Instead we share libraries, and have frequent conferences to learn from one another.

I love when a customer wants to learn to tune themselves, and encourage them to take what they've learned and apply it anywhere they can. I always say, teach a man to fish...
