OFT?
 

I have the OFT v2 but was wondering if it's possible to do anything besides the off the shelf stages, custom pop tunes etc.

In my head I would think that if you have access to a lot of the parameters you could maybe do interesting gimmicks (idk valet mode for example) but haven't been able to find anything besides the ones we all know about

Appreciate any responses :)

Yes.

Correct

Yes as in there's nothing else you can do?

Your question asked if there was other stuff you can do. The answer is "yes"

Like what? Can you link please:w00t:

I can't. I never had an OFT. But I have been on the forum for like 7 years and I am positive I've seen people talking about modifying maps. So I know it can be done, I just don't know how. I recommend searching the forum in the engine tuning category or Google/youtube

It's an open source device. You can custom tune, you just need to find somebody willing/wanting to use your datalogs to revise a tune for you.

Not being a smart asss but if you are asking the question be very very careful what you start playing with. Bad tunes are pretty much the number one killer of engines on this forum. They far surpass the recall failures that everybody gets so worked up about. Valet mode is safe but you start tuning for pops on your own you may get a bigger bang than you want.

Did you look in the software tuning forum?

Have fun. But like @Tcoat said, you’re playing with fire if you don’t know what you’re doing.

I have used rom raider to edit the tables to known VVT values for headers and to bump the idle rpm, but I don’t trust myself further than that. Pops and bangs are a sure way to clog your cats and you could damage your engine irreversibly. That and pops and bangs make you look like a total twat.

oh yeah don't worry I haven't really done anything myself, was curious to know if it can do anything else easily (I have tried the pop thing for like a week before lol)

Common things to start with are toggling FFS/LC, MAF scaling, adjusting the IAM, changing delay factors, O2 scaling, and VVT adjustment for aftermarket headers. ROMRaider is the tool of choice for most OFT modifications.

V4 tunes do not need a lot of adjustment on a stock car (at least not on mine), though going through the motions to do them is a good way to get familiar with the tools and methods. I think my current tune has a lower cl-ol delay, .9 IAM, and I backed off timing at higher ambient temperatures.

As for advanced stuff like changing the logic for valet mode and such, it CAN be done, but it is well beyond my knowledge level.

A GOOD tune when loaded runs perfectly in minutes. A POOR tune needs hundreds of miles for the ecu to adjust unsuitable settings ie timing and fuel mixture. The ecu does this normally for changes in fuel and operating conditions but should not need to do it to a poor/dangerous tune.
On a second note if something goes wrong when installing the tune your ecu is toast! Not that it will happen but the more you change them the more complacent you become and the greater the chance.

So if I use a tune that is listed and not a custom or downloaded tune I will be fine? Such as the e85 or stage 2 that is already on it?

Probably yeah. Preloaded tunes have already been dialed in pretty well

Sweet. I’m still learning so I am doing more reading than anything. Thanks

The V4 tunes are shit. It will be safe, but they are not great.

Honestly I think the majority of people here rather safe than sorry to pull like an extra 5 to 10 hp more out

Yeah ofcourse I try and keep flashing at a minimum. Question though, let's say ecu is toast, is it just an ecu replace or the engine as well?

Just ECU. He's talking about the flashing process getting messed up halfways through and getting stuck

Side question, the OFT website says "stock or drop in air filter" for the intake for all the stages. I've been running a stage 1 with a cold air intake with no issues. Was wondering is this bad if I continue to stage 2+? Don't really wanna remove the cai but want to go to 2+ with it

Last thing, for some reason in my head I tend to believe not to flash the car when it's hot and wait till cool down. Good practice or just some mumbo in my head?

Cold air intakes change how the air flows across the mass air flow (MAF) sensor. You can correct for this in the tune. Look up the MAF Scaling thread in the software tuning section of the forum. Without correction, the engine will probably still run decently as you have noticed, but it will produce less power, less reliably because the amount of air it thinks it is using will be wrong.

You can flash the car hot. I would do it all the time when making adjustments.

Note: Stage 2+ is for cars with catless headers iirc. You probably know that, just making sure.

Have you been to the software tuning forum?

I think you are misinterpreting me saying they are shit= making less power then they should.

What I mean, is there seem to be a lot of issues with the V4 tunes that people have had. MAF compensation tables not being correct, weird idle and throttle behavior. There were issues with their previous revisions too, but V4 seemed to have more issues when it should be more polished. I also don't like that they default IAM to .7 instead of 1.

I'm gonna be honest I went and don't understand most of what's going on there

I found V4 to work better out of the box than v2. :iono:

okay so the intake I have is this

https://www.knfilters.com/cold-air-i...0l-h4-gas/2013

I'd really appreciate if someone could help find the right MAF value I'm supposed to look for, and where in the OFT you would change it. Very new to this, the software section in the forums is seeming too complicated and can't find a finished thread on this :(

Also yup just installed catless headers a couple days ago


Edit: Just wanted to clarify I bought the cai used just for the sound, I know it doesn't make any power difference but I really like the grrrrrrr sound it makes

Strange. I had a lot of issues when I tried to copy the tables I was using based on 2.07 over to V4 and had all kinds of issues with the way the car ran. Flashed an untampered with V4 tune over and it was worse :iono: Ended up reverting back to my 2.07 file.

Steps to find MAF scaling thread:
1. Google
2. "ft86 maf scaling"
3. First link.

Read and reread the first post until you know what parts apply to your situation and what you need to do. Doing this right takes a bit of effort to learn what is going on and how to set up your tools first, then you can actually start changing things safely.
Alternatively you can pay someone to set it up for you, or revert back to stock intake.

I just started with basic V4, and redid everything from scratch. Might be easier for me because I don't have physical power upgrades?

So if I have headers and exhaust, I’m safe to use the stage 1 already loaded on my OFT? And am I safe to download a set off the OFT website that is specially for my vehical 2013 FRS 6spdMT?
Does anyone have a link to one that is safe to use? There are so many on the website I don’t know where to start
I’m not really into the pop pop bs tune that the previous owner has installed

101% Learn how to MAF scale. It actually is easy, like most things, once you have done it a few times. Just start with copies so you can fall back to the original if you stuff it up.

Is there a tutorial I can watch or read for the maf scaling

And can I change my current tune to a new one without reverting back to the original tune or do I have to revert to my original tune from my current in order to install a new tune?

Sorry I know I have lots of questions but I get like this when I want to learn something inside and out

Yes you can install any tune one at a time in any order. When I said original I do not mean the oem original. I meant A copy of the tune you are going to modify so if all else fails you still have the untouched Stage1 or2 as a backup.

There is information on here that will get you headed towards maf scaling in the software tuning section. I don`t remember where because it was a long read, a long learn and a long time. Ballpark figure would be a working week of time(for me anyways). So read guides follow links and watch youtube associated vids and practice with Open Flash manager, RomRaider https://github.com/RomRaider/RomRaid...20-windows.zip and (Maf Scaler) Nice)https://github.com/vimsh/mafscaling/...ags/v2.7.0.zip

What is romraider for? And do I need it? And I assum maf scaler if for the MAF. But I don’t need anything besides OFT the install standard tunes right?

If you have the stock intake you don't have to worry about MAF values and just download the tune files from the openflash website from your account and flash the car. If your car doesn't have aftermarket headers you can go to stage 1.

The issues I'm having is that I don't wanna revert my intake back to stock just because of the sound and would rather try and learn this maf stuff

RomRaider is for editing ROM's. You don't need it to use "off the shelf" tunes, all you need is the OFT.

Another great source of ROMS is WayneROMS, but those are not free. However, getting his ROM's is a much easier process than getting them from the OFT site.

You have the Open Flash Manager for getting ROM's on to the OFT, correct? The DL link is at the bottom of the page.

After installing, I have found that it's better to disable your internet connection before starting the manager, or else you get a very long startup/upgrade process. Also, try to use a USB 2 port rather than 3. I had nothing but trouble with USB 3.

I'm assuming you mean editing the ROM with ROMRaider and complacency. I have dozens of flashes, trouble-free, and there must be a few people like Wayne or Steve in to the hundreds. An OFT brick is rare. The trouble is wrong tunes, or as you say, making an error in editing the ROM.

As it is now, I have no desire to edit any tune or whatnot. I will stick with OTS OFT tune and keep researching until I am comfortable enough to tinker. I need to upgrade some things before I do too much to push the motor more than it was designed.

I have unequal length Tomei or groups-s headers, and they are catless I’m almost positive. Smells like it. With a non stock exhaust. So from my understanding I should be using strage 2+… please correct me if I am wrong.
