I would like to run it to the other side of the dash for logging and also not have the cable pointing down from the port just above my right leg.

2. I have a OBD Bluetooth adapter that I was using with the Torque app. Since installing the OFT, it no longer connects to the ecu. Is that a common issue? Works fine in another FRS, non-OFT.

1. I use a right angle OBD adapter as well, and don't have an issue, double check the cable?

2. My BT obd adapter works fine also. I'm wonder if you don't have something a little wonky with your port.

Does the OFT plug in without the extension just fine? if so, try the extension with the bluetooth adapter in your car and another car.

Is there a customization for example, for someone who has just a UEL, intake tube and catback? or does it not get that specific?

Thanks for any help!

have a read of the OFT TIPS post below

intake tubes drop in filters ,cat backs dont effect tune required

its rearly only the header UEL or EL and removal of cats that change tune requirements

intake change ie a full CAI will effect maf scaling but you can do this youself see below, in most cases leave intake alone their is little to be gained over a drop in filter in standard intake and modify snorkel if your rearly keen.

What's the length of your cable? Mine is 4' long, perhaps too long to maintain the signal. Probably 2' would do.

Not sure on adapter. Connects to phone, just not reading ECU.

OFT connects without issue, reads fine without extender cable.

Those are for the different CAL IDs over the years. Stage 2 UEL, as steve99 mentioned, will cover any setup with a stock airbox. Shiv's OTS tunes should really be treated as basemaps in many ways and if you are getting large fuel trims you should look at scaling your MAF.

I have a 3' right angle cable and it works like a charm. I doubt your problem is the cable length. More likely a faulty cable.

Thanks for your help and input -- I did a quick search to try and understand what you meant exactly but no solid answers come up

but from what I can infer.. you are basically saying that the OFT tunes are Okay to unlock most of common setups potential power but need to be edited/calibrated after being checked against logged data to get the most performance. Is that right?

Before I scour this entire thread and forum, are there any guides or tutorials you could point me in the direction of (recognizing a large fuel trim, the average fuel trim levels, how to scale the MAF)?

thanks

edit: never mind I am going to read the entire romraider site first sry

also may seem silly but wouldn't it be a good idea for people to share their tunes of exact setups? there's probably trust issues or other problems involved I presume?

edit2: also I think it would be nice to know exactly what aftermarket parts were used to mold these 'basemap' tunes to the way they are, like say the OFT team decided to use: x header, y front pipe, z overpipe, x catback to create the "93 octane stage 2 UEL header tune" // or if they simply created the basemap while using just an aftermarket header and stock everything else etc.. (sorry if this is answered somewhere, just a thought)

steve99 has some great threads on DIY stuff with the OFT. It would be great if people did share their tunes but 95% of people just run the OTS tune.

The UEL tune is based of Shiv's own OFH but should work fine for other UELs. The EL tune was based off a prototype or custom EL that I haven't heard much about. I suspect the stg 2 EL tune could be optimised for different EL headers, particularly the cam timing but again I haven't read about anybody really messing with that.

Lots of info on the romraider site that is for sure.

Thanks man you the best. Seems like there is a lot to learn for semi-perfectionists like myself who won't be able to even sleep if their tune is off by a little.


Could you guys also enlighten me about the pros and cons of going with something like the Unichip instead? It seems to have a much deeper and specific library of pre-tested/pre-made maps while still allowing for user adjustments. Very curious about this

Once you have a flashable ECU and the tune tables are known like with the BRZ/86/FRZ then I cannot see the point of a device like a uni-chip.

You have to wire it in
It obvious to dealers
It is only "fooling" the external sensor inputs to make adjustments to the engine performance, very limited adjustments available.
I suspect this is why they have to offer so many different "tunes"
Great for ECU's where no flashing option available.

With a flash tune your changing the specific tables that the ECU uses
Much wider range of changes and adjustments available.
You not fooling anything your changing the actual values you want to change in the tables directly used by the ECU program
Their are hundreds of these tables available.
It virtually undetectable
Can be flashed back to stock spec in minutes. no wiring ect.
Most flashing devices/systems offer a means of logging your tune allowing you to see exactly whats going on in real time or storing logs for analysis.

you can update to later version ECU software released by manufacturer.

You can make adjustments based on this logging information.
Logs can be sent to professional tuner for analysis and adjustment.

Allows for additional features or functions such as Launch control , Flat Foot shifting.

Answer Edit 1 :People can share their tunes but you have to trust that the other guy is not a "wombat" and has produced something that is either rubbish or may in fact be dangerous to your engine and is suited to your mods and the ROM is compatible with your car.

Answer Edit 2 :

Talking Naturally Aspirated BRZ/86 and "bolt on mods"

Its fairly proven that Headers (generally catless) produce the most gain and hence require the most "tune changes". Changing the rest of the exhaust ie overpipe/resonator/catback , has little effect on the required tune or power/torque. After the header little hp to be gained it mostly change in noise/rasp level.

Intakes again appear to produce little gain and in general will require you to rescale (or calibrate) the mass air flow sensor to suite the intake . Most aftermarket intakes offer little benefit over just changing your stock filter for a quality drop in filter and maybe modifying snorkel and this wont upset MAF scaling.

Yes a dedicated Dyno tune for your specific mods and fuels may squeeze out a few more hp, but where I live thats about $1200-$1500 plus I pay for updates or changes and I leave with nothing but the "tune" in the car.

As opposed to an OFT and a "base" tune for $500 I get tune & updates thrown in I can change tunes as mods added or removed, E85 tunes are another bonus, I can flash to stock for dealer visits. I have a device to flash tunes and log engine parameters read/clear DTC/CEL codes and I can on-sell it if I move on to something else.

Probably 95% of gain for one third of the cost and I can on-sell it.

Any idea what the solution was? I've tried on 3 PC's and i cannot get OpenFlash Tablet to connect to OpenFlash Manager

Make sure your Open flash manager is up to date, if its an old version may not connect to Tablet

download and install from here

make sure you update template files as well once you get connected

Running the latest oft manager software still the same exact issue in three separate machines

[coeurdencre]

I received my OFT this week and it worked without problem with OpenFlash Manager.

I got the "Cannot create a Tuning file." message after I read my ROM. I sent my stock ROM to Shiv and hope to get a quick reply

does not throw up any errr message ?
knd f out of ideas if its a rearly new pc maybe it does not like usb 3 ports, best contact the openfash guys.
