+1 on what @Kodename47 said


on stock tune the 02 sensor only reads down to 11.2 even if actual afr is much richer.


look at the throttle their is a big dip round 6400 as kode said look like trac kicked in and closed throttle.


I don't think ecutek logs IAM if you don't have racerom in ecu for some reason.


looks like stock tune to me judging by target afr in 10 range, so looks pretty normal for a stock tune

Thanks, guys! Yes, there was a loss of traction. And @steve99 you are correct that IAM wasn’t an available parameter on the stock tune (no ECUTek license).

@Kodename47 I’m not sure if FLCK or engine load were available as I was borrowing a computer and cable, and it was set up for me with a default set of parameters.

The point of the log was to make sure that going to a 2013-2016 airbox on my 2017 doesn’t necessitate a tune. This swap was needed to allow room for an oil cooler.

I saw recently on Facebook that the OFT will now log 2017 cars, but I haven't confirmed. If the OFT works for IAM, FLKC, etc., maybe I'll get one and do some more logging.

the ltft are getting a little high like -10 in places so when you get tune it will be worth rescaling maf to reduce those trims and get afr and commanded afr close during WOT. you may need to rescale o2 sensor to read richer to d this depending on fueling

@TheRacersLine - FYI. Sounds like a tune would optimize the airbox and intake elbow swap. Or just the stock tune in general. Dammit...LOL

Read this twice and still confuse mainly due to descriptions on websites..

If i want strictly Ecutek bluetooth dongle, and Etune what else do i need other than a Vehicle License? Is the vehicle license the same as software license?

With the old programming kit, there is also an encrypted USB key/dongle included. Without this dongle the ProEcu software doesn't run, so you need to purchase this dongle as well, as it's not included with the BT Vehicle interface.

With those 3 things: Dongle, BT VHI and license you can flash a tune you purchased somewhere else.

If you want to do DIY tuning, you need to additionally purchase RaceRom extension.

I thought the Bluetooth interface cannot be used to flash the ECU.

It can indeed but not via BT. It has a mini USB port, so it's over USB. But you need the dongle as mentioned.

Does ecutek stock ROM now includes 2017 automatic models? Specifically with push button start?

Yes includes K00D, push button or non pushbutton start have same ecu calibration

One downside for ecutek is once flashed, the trace will be detectable in ECU unlike OpenFlash you can completely remove it before going to dealer for warranty works. Is this true? Any way to get around it?

Sigh.....

To be "able to tell" if a car is tuned will require more equipment that a dealer has. They certainly can't connect to the ECU and it tells them that a car is tuned.

The EcuTek license will remain in the ECU so this could be picked up by forensic checking of the ECU but this is not something the dealers would do, but Subaru/Toyota. If an EcuTek tune is on the ECU then the dealers will not be able to re-flash the car. If you flash a stock ROM on with EcuTek this is not the case but then if the dealer flash over it you will lose the EcuTek license. Then again if the dealer flashes over an OFT file then you could have your CalID changed and cause issues with the marrying of the device.

TBH I don't know why you'd bother to go back to stock, I never did on my car. Then again the US dealers seem more likely to reject claims....

Unfortunatly the dealer can easily check with their tool.


however a kodename 47 said it not a routine practice unless they are looking for evidence, and required a little research by the dealer technician.


They need to read the CVN and the Calibration ID then look up and compare the values.


Parameter called CVN Calibration Verification Number is available via dealer tool, this is basically a checksum of the flashable area 8000-13FFFF


each stock rom has a set CVN, so they would need to look that up and compare it with the CVN read from vehicle. If its different to stock rom of same calid , bingo got you.


this is different to the Calibration ID which does stay same ie like ZA1JB01C or whatever it is.


[18:27:03.414] CALID : ZA1JA01D
[18:27:03.429] CVN : ED0690B9
[18:27:03.429] VIN : JF1ZNAA12D272


Any type of tune from any tune system will be detectable as CVN will be different from a normal stock rom of same Calibration ID


with Ecutek the embedded licience will alter the CVN as its a 14 byte string just after 8000 hex in the flashable checksummed area of rom, so even ecutek "stock" roms are detectable.


It possible to remove the ecutek licience with ecutek using a special switch then flashing, but in doing so you will loose your ecutek licience and need to get it renewed or buy a new one.


or if you wrote over your stock ecutek rom in ecu with another flash tool again licience will be lost. this also happens if dealer reflashes your stock ecutek rom in ecu.


any modified ecutek rom has access keys changed to dealer cannot read or write rom , but they can still run diagnostics and read stuff like CVN and Calid and discover rom is not 100% stock.


note the "flash counter" you see in ecutek is put their by ecutek its in that 14 byte encoded string, so its not readable or useable by dealer.

wow, it's kind of scary dealer would reflash ECU during dealer visits. OpenFlash doen't have to deal with these issues?

a question
Ecutek kit is: cable + dongle, then you need a license for every single car


Is the license contained in the dongle? or is it just downloaded digitally from the ProEcu software?
I mean, if I borrow my ecutek cable to a friend, and he wants to use my cable he will then buy a license from a master tuner


How does it work with the new license for him? will he receive a new dongle or just use mine ?

if you leave ecutek tune in ecu then ecu is locked and dealer cannot flash


If ecutek stock rom in car yes they can flash


If you keep receipt from dealer ecutek will in mosr cases replace licience for free.


openflash or Tactrix don't lock ecu so dealer can always reflash and theirs no licience in ecu with those systems.


OFT can be a bit of drama if you did not unmarry oft , and dealer reflashed to different calid. but you can just write over it.

Yes you need one ecutek licience for every ecu you flashed this ie ECU Licience, the dongle id is Ecutek kit software licience you only need one of those


once ecu has licience (its transferred on first ecutek flash) then you can flash that ecu as much as you like.


Dongle just liciences your ecutek software and tunes.


Ecutek ECU Licience is separate


Yes you friend can use your dongle/cable kit to flash their 86/brz but they will need to buy a ecu licience.


the licience will be applied to dongle id so next time you go online with your ecutek kit licience is downloaded to PC.


when they flash the new ecu that licience is transferred to ecu in car.


Any tunes from a tuner would then need to be licienced to your dongle id.


If you made up an unlicience/locked tune then anyone could flash it with any ecutek kit

Why? It's common practice, in some dealers/networks, to update the ECU to the latest valid software when doing a service/warranty work. If they do this as they see you're on older software, some would say they're being nice ;)The ECU license is indeed downloaded digitally when you do an EcuTek update. If he's using your equipment to do it you would get the license applied to your dongle ID. If you flash your car it will know there is a license on the ECU and a comment in the flash box appears with something like "Flash will not consume a license." The license would be used up on the next ECU that you flash that does not have EcuTek on it.

what are the different possibilities one can use to totally remove ecutek license and "fix" the CVN code to become as stock as possible?
you could do also with ecutek then?
Can you also do it with techstream? or Tactrix? (but which cable you have to use then with those last two? )

My PC is a Mac. Does that matter for the software? Sometimes PC means Windows to people instead of personal computer.

So the $25 cable is $350? The $10 usb stick, sorry dongle, is another $350 too or is it included? I ask because people seem to be selling used cables and dongles or just cables, and I am trying to figure out what all is needed. Then a software license key is bought for another $350? Then a tune from a shop or Delicious is another $350? Someone can't sell their license, right? Unless they haven't used it to flash anything, or never? And someone could or couldn't sell their flashed ECU?

Reading the OP gave me a headache, as a series of unconnected facts seem to be assembled in a convoluted way. I'm guessing it is my sleep deprivation than his typing. I will attempt to reread the OP tomorrow.

Ecutek cable kit comes with cable and dongle, you need both or its useless and software wont run.

correct licience stays in ecu not onsellable

it would be possible to sell ecu with licience but you would need to use ecu swap proceedure its not just plug and play

read the first post

Cable kit includes your dongle and your cable. The “dongle” is a DESkey which is a form of software security key, similar to the old software key codes system but much more sophisticated. Prevents coping of the software.

The license file is a string of code that gets embedded into your cars ecu. Can’t be taken out of ecu and sold. It starts off stores to your software and your specific dongle identified software. You can sell it before flashing to your vehicle but only as a kit with the dongle and license, cannot remove and sell only license.

Ingredients to tune a car that’s never been touched by ecutek before are:

Cable kit (dongle and obd ii cable)
Ecutek license
Tune file (from your chosen tuner)

PC in this case is indeed referring to a Windows device (although it does indeed stand for personal computer). Not Mac or Linux compatible.

Can sell a flashed ecu and will work fine in your car if you sync it properly.
Second hand cables are worth Jack shit, the “dongle” allows use Of the ecutek proecu software.

So the only person who would buy a cable without a dongle on the used market is someone who may have done a flash then sold their cable but kept their dongle and now wants to retune the ECU.

What about the license? How would anyone know before purchase that a license hadn’t been used?

Plug the dongle into the computer, fire up the ECUTec software and it will tell you.

not rearly


without a "dongle" you cannot run ecutek software
without ecutek cable you cannot flash , you cannot use say a tactrix cable instead, must be ecutek.


A lot of people think the ECU licience or tune is in the dongle , its not.


The dongle is just a "licience key " for the ecutek software.


The ECU licience is completely separate, you need to buy or have a new ECU licience for every ecu you want to flash.


The dongle key only allows ecutek software to run.


don't buy a ecutek cable without a dongle key, its useless. you would nedd to buy a new dongle key to get software to work, then you also need an ECU licience, and a tune to actually flash a car.

I have a Harrop kit I bought used. I was going to wait for them to finish their CARB approval to install the kit, but if it takes forever I may get impatient and do a Delicious tune. At minimum I will need to buy a license ($350) if Harrop hands out their tune like Edelbrock did, that is, if I get a buddy with a cable and dongle to flash my ECU. If I go the Delicious route then I will need a license and their tune ($350 + $400) with the help of the buddy. If I want to data log or make updates then I should buy the cable and dongle kit ($350). So I could be in this for $350-1100.

Then there is a blutooth kit for an additional $350 to be able to use some functions and view some data over a mobile device, but that kit doesn't replace the cable and dongle kit; it is merely a convenience add-on, so the bulky computer isn't in the passenger seat like in Fast n Furious telling you about your manifold pressure blowing, right?

Im not sure if ecutek package a blutooth adapter and a dongle, but it might be a cheaper option to but dongle and blutooth adapter separate as you can use blutooth adapter to flash as it has a mini usb port on back of blutooth adapter


Or you just buy bluttoth adapter and borrow your mates dongle when you need to flash.

Seems like the Bluetooth module could be used to flash ECUs but they don’t put that function into the software n hardware.

Blutooth module will definitly flash cars i have one and used it to flash. But you use the usb interface on module and the PC based ecutek software and you need dongle as well.

But yeah it definitly wont flash using the blutooth tablet\phone software vie blutooth

I have joined this forum. Not because I own an 86. But to gain more info or to share my experiences with Ecutek.
I currently own an Australian spec Subaru Levorg with the 2.0 litre DIT which is the same as in the current gen WRX.
I went the Ecutek route due to wanting an etune and it was one of the easiest way of achieving that with off the shelf items and software. Albeit a bit expensive.
After finding a tuner who was willing to take on the task after trying one who failed miserably. Things are beginning to progress nicely with my tune.
Due to the time difference of being in different countries we have refined our workflow quite well.
The Bluetooth dongle works brilliantly for this.
What we do.
1. Log using dongle.
2. Upload using phone to shared OneDrive folders
3. When a revised rom is available. I download from OneDrive to a laptop and flash the ecu.
4. Rinse and repeat.

No requirement for emails as we chat through messenger.

My program failed due to faulty connection just after starting. I now have it reading consistently, but it tells me my license is consumed and cannot write the full tune into the car. Is there a way to salvage the license from a partially written ECM?

Call Ecutek, they can do it remotely.

On 1st write or subsequent flash? If the latter you can usually get around this by manually selecting the vehicle and flashing that way.

manually selecting did work after bending pins in the ECUTek adapter. Then it has problems with a missing license. ECUTek gave me a quick turnaround in getting a replacement license. It's working again, Thanks

I was thinking about buying the ECU connect bluetooth interface, USB dongle and a license. Does the Bluetooth interface eliminate the need for both the OBDII cable and the software programing package?

Yes. You need RaceRom too if you want to do any editing yourself. If you get someone else to make the tune for you, you are set with that stuff you mentioned.

If tunes are keyd to the dongle, what stops user from sharing the tune with another car if they buy another ecu license?

Locked tunes don t open if you try to open them with a dongle that has a diffferent 6digit ID to the one they are keyd with
Open tunes open everywhere with every kit

Thats possible but you have to ise dongle tune is keyed to, the tune is also not editable if its keyed so you cannpt open or change it jist flash it.


The second car would have to be same or compatable ecu calibration id and car have same mods
