Need OpenFlash Tune for TRD catback and Grimmspeed intake and crank pulley
 

Hello,

Anybody know where I can download?

Am pretty new with the OFT.

Thanks in advance!

You my friend just need to load in a stage 1 tune and call it a day.

It's enough? What is the gain you think?

Enough for what :iono:

Sorry, I mean it's the best with my setup? Or we can get better instead of the Stage 1...

I know a special map exist for the Grimmspeed intake somewhere...

Just asking...

The catback does nothing on this car (none of them do). It's cosmetic, for sound. The intake, barely nothing. You'll see a 5-10 WHP gain. A drop in filter would get your roughly the same results with a tune. The current off-the-shelf Stg.1 tune is the fine but if you want, here is the thread with the Grimmspeed tune from a couple years back. http://www.ft86club.com/forums/showthread.php?t=78903 You can bump up to the Stg.2 tune when you get a header.

I have already check this thread did not find anything unfortunately...

Ok then will use the Stage one if this is everyone suggest.

I think you have to realize you're going to get miniscule gains from the mods you have done, if you want serious power increase you're gonna need uels and a high flow front pipe, then you'd run the stage 2 tune and make more than 15-20 hp

Yes I know :)

But there are any advantages of the Stage 1 aside of the little HP. I think response? And avoid the injector problems?

The engine runs generally safer, and will respond better to the catback, pulley and grimspeed intake, also 10-12 whp isn't that bad.

Perfect!

Thanks everyone.

I personally felt a gain with my catback.

So with the stage 1, catback and intake, car will feel great man and you will have some good gains and overall will be a huge improvement over stock!

That what I want :)

It won't be... BUT if you put e85 in the car and switch to the OFT Stg.1 e85 tune (which is free), THEN you will feel a huge improvement over stock. If you don't have e85 in your area, then you won't feel a huge difference until you get a header. Sell the intake and catback, get a header and drop in filter. You'll smoke everyone that has a header and catback on the regular.

Yes it will be.

This is also a great video to watch.

Sooo.... sure, let everyone see your dyno that proves that just a CBE provides enough extra WHP to show up repeatedly on a dyno. Or you could just search the board for early 2013 when a bunch of CBE were dyno'd and gaining practically nothing without a tune. Or read which part mfgs opted to not produce CBEs because they gain nothing without a tune on this platform either. It's the tune making the power not the CBE.

The best I've read is a 2-5 TQ (not WHP) gain in the midrange specifically with TRD USA catback due to its' tiny 2.25" midpipe that via raising EGT and improving scavenging at the expense of losing 1-2 WHP. Oh btw, I actually own a TRD CBE. You too right?

Please don't spread anecdotal butt dyno (mis)information without proof. If you have it, please post it and accept my humble apology.

I can't use e85 for the moment...

Grimmspeed intake is not supposed to be the best intake on the market right now where you can feel or you get the best Improvement vs the stock box?

Just asking because they seem to have done a lot of development on this, maybe at least it's better compare to a drop in? Anyway, I have this intake for the look, the sound and to remove the gazoo...

Am not looking for a lot of gain with this setup, I know intake and CBE are not the part who gave a lot of HP gain... Am just looking to know which tune is the best for my current setup...

I know also the TRD exhaust is probably not the best exhaust to get gain whatever an CBE can give on this car... Again it's for the sound and the quality of the part...

And yes, I know Headers will be the best mod for the money... Anyway, I will be ready for an tune if I have already the OFT.

Thanks guys!

So far, no intake has demonstrated any gain for NA. A few of the early ones have shown losses. General recommendation is to not get an intake unless you want one for cosmetic/sound reasons -- the stock one has sufficient flow and is a true CAI.

Maybe but will not loose any power with the Grimmspeed, I don't think so...

But wait, What's about the numbers they provide to us in the forum?

There is an OFT Stage 1 map specifically for the Grimmspeed intake. The only difference between it and the standard Stage 1 maps (any octane) is the MAF scaling. You will have to e-mail Shiv at OpenFlashPerformance with your make/model/transmission/CalID and desired octane level.
In my experience, there is a slight difference with LTFTs between the standard Stage 1 and GS Stage 1 which could improve fuel economy over the long run. Nothing serious though, and certainly very little, if any, hp/tq improvement between the two maps. All of your hp/tq gains and curve smoothing will be accounted for between the hardware you've installed and any Stage 1 map.

Perfect, will email Shiv in time I have already make a contact with him yesterday but I do not have my car with me a the moment...

Didn't gain much from the Grimmspeed intake with OFT FYI. I'm running e85 though so results might be a little different.

You also might want to do some research on maf scaling. My fuel trims were a bit off after putting on my Grim intake. If you do a bit of digging one of the members on here posted his 91 tune with the Grim intake after he did a bit of Maf scaling. I have it some where. I'll post it up if i can find it.

The OFT Stage 1 will work great with your mods.

The more you research the more your head will hurt haha.

Headers are great, just remember that if you get catless, it will smell and be very loud especially with a TRD exhaust.

If you pay close attention, nobody has given dynos comparing a tuned car versus the same tuned car with all things equal other than new intake and new MAF scale.

It is always untuned VS tuned, or untuned VS untuned, which are invalid comparisons to judge an intake's effect.

Am the one who search a lot before doing any mod... By car is based on that and run very well with all about I have done since now.

Yea I know about the headers this is why i am planning to stay stock from this side...

Thanks

Well, the untuned vs untuned comparison, which Grimmspeed posted in their announcement thread regarding their intake, is valid for the purposes of determining if the intake alone has a benefit (Grimmspeed's benefit is around 5 whp). However, I agree that there have been no reliable tuned vs tuned comparisons, which of course means that the OFT may indeed be able to compensate for the hp/tq gains through mapping alone.

To expand on what others have said in this thread, my only suggestion for those interested in this combo of hardware and mapping is that should you think you are interested in a header, save your money and do not purchase an intake. The additional hp/tq (if any) is negligible as compared to the header and mapping, particularly when considering $/whp or $/wtq spent. Without a header, I am inclined to speculate that there is a minor benefit to the GS intake, and perhaps other intakes (although I haven't researched them recently).

This simply isn't correct.

Would you please share your reasoning behind your statement?

But let me clarify - the intake has a benefit in a stock, untuned car, based on GS' dyno results. I am NOT saying that the intake definitively has, or doesn't have, a benefit in a tuned car as there haven't been tuned vs tuned comparisons. Hopefully that was clear in my prior post.

I personally feel purchasing a intake and exhaust for anything but looks is a waste of money and any gains you think you feel are just because of the added noise these parts create. I also didn't fell like the stage 1 OFT tune on 91 made any real noticeable difference and I would prefer to just keep the stock tune.

Switching to E85 with no other mods made the OFT purchase worth the money. Night and day difference in power can be felt throughout the whole rev range. If it wasn't for the E85 tune I would have just sold the OFT.

We have very differents opinions here concerning the OFT now...

Just remember that all of our opinions are just that - opinions. People's perceptions are based on their own experiences. For example, up until 2 years ago, I had never owned a vehicle as powerful - lol - as the BRZ. I was very impressed by the Stage 1 93 octane map and further impressed by the Stage 2 93 map with OFH. I can't speak to the E85 maps as of yet, but they do clearly improve upon the 91 and 93 maps, obviously due to them harnessing the magical power of corn. Other people who have made major modifications to their cars in the past, releasing 20, 50, or even 100 additional whp/wtq will likely say that the OFT maps are not all that remarkable, simply because their experience-based perceptions are different.

What matters is that the facts are clear. The OFT Stage 1 91/93 map alone improves whp at the top end of the rev range and greatly improves torque within the torque dip (~2500-4000 rpm). The Stage 2 91/93 map improves upon the Stage 1 as a result of harnessing the benefits of a more free-flowing exhaust header. All of the OFT maps greatly improve driveability below 4000 rpm, which is where most people spend most of their time. Whether or not you will perceive these improvements as worthwhile is really a personal matter. For the money, the OFT/OFH setup remains the best bang for most people's buck short of forced induction.

One way I like to judge the value of vehicle modifications, and how I spend my money, time, and effort, is to quantify the improvements I propose making relative to what I have. While it's hard to quantify "driveability," it is easy to look at the improvements in whp and wtq. Depending on the rpm, people running OFT/OFH are looking at upwards of 10-15% improvement in these measures of car performance. To me, that is significant; to others, maybe not. A good example I have from my experience is when I was modifying my motorcycle, which makes a lowly 23 whp from the factory. People asked me why I spent several hundred dollars on mapping hardware and software which only promised ~5 whp gains. Well, 5/23=0.217 - I was spending about 600 dollars for a low-effort gain of nearly 22% whp! That, to me, was incredible, especially considering other lower impact modifications on the market for other vehicles of all shapes and sizes. Furthermore, going from 23 to 28 whp on a 340 pound bike is definitely noticeable. It's all in your perceptions of value - a very personal matter.

I've posted these on here before but here are a couple dynos

This is OFT e85 Stg2 and k&n drop in filter, Borla axleback

http://i648.photobucket.com/albums/u...38056560_2.jpg

This is e85, Grim intake, Tomei overpipe & UEL header, Berk front pipe, lightweight crank pulley, and HKS catback

http://i648.photobucket.com/albums/u...cfa30c34af.png

Keep in mind these are two different dynos. Same tune. Didn't gain a whole lot of power with all those mods and not sure if that gain was more attributed to the header. But take these results with a grain of salt.

Maybe will do a dyno before and one after to see the real difference...

I have posted this before I'm surprised nobody noticed, You just have to copy the MAF table in romraider and your good to go. https://docs.google.com/spreadsheets...R3Y/edit#gid=0 It's seconded to the last.

Thanks! Very nice sheet
