This is the question people that really needs to be answered. In the past, when ecutek was installed on certain subaru ecu's it could not be completely removed. As a result an owner could NOT install another tuning software such as Cobb AP or OS on that ecu. The ONLY solution I'm aware of involves getting a new ecu. I had an Ecutek license for my 04 WRX and fortunately Crawford was able to swap ecu's for me when I wanted to switch to Cobb AP.

I guess since Ecutek will be the first to release their product (as they were with the WRX) they won't know if it any other tuning software can be used on an ecu after a Ecutek tune is "removed". I personally will wait until other tuning options are available to find out if there are any other compatibility issues.

Very interesting.

Ok, time for substantive questions. I see the torque calculation map, which is fine, but it's rather minor. Assuming EcuTek reverse engineered it correctly and the load axis is really grams/rev like a Subaru, somebody explain a few things.

1) What is the timing and knock control logic? Does it use a dynamic advance multiplier like the older Subarus? Does it use a calculated octane value (in RON)? Or does it use a basic "high octane" and "low octane" map with interpolation? Does it have an MBT calculation and a borderline knock timing calculation?

2) Have you found the injection timing maps? For both port and direct injection, does the logic go by start-of-injection or end-of-injection? Is there some kind of wall film compensation model for tip-in fuel?

3) There must be some kind of commanded air fuel ratio. Does it use open & closed loop areas, or closed loop through the entire operation? Is there an enrichment/closed-loop delay timer logic?

3) Have you found the MAF sensor scaling?

4) Have you found the cam phasing maps?

5) Can you turn on or off the diagnostic monitors and diagnostic trouble codes (check engine light)?

Please provide more information on what you guys have control over. The Japanese control systems (Denso, Hitachi) don't use full torque-based control like Bosch, Siemens, or Delphi do. So finding that map has limited usefulness.

Hey Guys

The EcuTek BRZ software is already very well defined.

Here is a old screen shot I was sent a few months ago.

There has been progress since then, but this will help you get a idea.

NICE! now someone start tuning! lol

I actually suspect this vehicle may have a non traditional control strategy compared to other Japanese systems. It is continually varying the duration of the port injectors, the duration AND timing of the direct injectors, AND the pressure from the high pressure fuel pump to achieve proper fueling. Also remember that the direct injectors and pump are actually controlled by another module, which will be running off commands from the main PCM.

This thing is not working off a simple injector basemap.

So things are moving forward quickly.

Lachute Performance has a BRZ and is the first to be working the new EcuTek ProECU tools.

If all goes as planned expect major updates in the next days to come!

I skimmed the thread and didn't see a price. Do we have an idea of how much the software/cable will cost?

Also, will the software run on Linux (Arch Linux or Debian in particular)?

Thanks!

Looks like its going to be a sales grab. A attempt to take market share before the sheep wise up. And they find out they are locked out and its to late.

As I still see no one has given a answer to the question.

Read the thread , it's all in there.

EcuTek's cable costs $350

EcuTek's license is $250

I plan on selling cables with a staged tune.

John

so if someone spends the $600 on a cable and license, they still can't modify their own maps to make a custom tune?

Yup!

Your going to spend $600 and not be able to make custom changes yourself.

Only ProTuners will be able to.

They're plans to release a copy of the software that will let you makes changes yourself but not during the initial release

Btw this is not a uncommon thing

John

Yes absolutely.

details of the development coming soon

Details and video ;)

a staged tune, would be like a tune for people that have upgraded exhaust & intake? is it possible to revert back to factory settings?

Each Vendor will be offering different things - I will be offering Staged Tunes with the cable - for intake and exhaust.

The more expensive option would be getting a custom tune in person or via email.


The less expensive option would be getting a EcuTek tune with-out purchasing their cable. It's cheaper but will leave you unable to flash back to stock and with out the ability to datalog.

Let me know if you have anymore questions

Thanks

John

So the staged tune with cable that you plan to sell, can be taken back to stock? DIY type thing?

Yup.

This is what I am used to for my AccessPort that I have for my Legacy GT. If Cobb is providing a free solution to users that have purchased their device, why are you saying it is not uncommon to have your product locked down?

Guess I'll just keep waiting until I can tune it myself. Any ballpark guess as to how long it will be?

Also, can you comment a bit on the interface for tuning the D4-S? Can you control all eight injectors separately?

Yes for your car it is free right now.

Normally right during launch Cobb does not offer a free version or any version of the software to a non - pro tuner.

This has always been the case.

Example - Cobb has no end user software for BMW

Example - Cobbs Gtr end user software is $800.

I've never said end user software would not exist - just said not now , ProTuner software needs to come first!

John

John - any luck getting the answers to these questions?

I posted a few screenshots the other day that should awnser your questions.

John

Ok, ECUTek has had some really bad PR in the past due to some questionable decisions. So myself and others would like some simple yes/no answers if possible, please.

(Peanut gallery, ethical discussions of map switching for service can be done in another thread. These questions are hypothetical only.)

Am I right in assuming that if we buy the cable, we can make a backup of our stock ECU so we can revert to stock at any time?

If a tuner uses their software/cable to write my ECU, can I use MY cable to revert to stock?

Can I use MY cable to back up a pro-tuner's custom tune so that I can re-apply it if I have to revert to stock for servicing?

After receiving a tune via ECUTek's software, will a standardized OBD-II data logger still work?

If not, will ECUTek provide free logger software that can save files in a common format (CSV file)?

Thank you.

I find assumption to be the mother of all **** ups.

I would like a commitment (in writing) that it allows full control over those areas.

Yes, yes , yes and yes

Some of the ecutek data logging is custom features that might not work with a generic data logger - but there is ton of oem stuff to log.

If you purchase the ecutek cable you can do a lot.

Backing up your ProTuner map can be done but will only be able to go back into your car- not another one.

Hope that helps

John

Awesome. It sounds like the new ECUTek product will give us the control over our maps that we as owners want.

Thank you for the answers. I'm looking forward to seeing what the tuners can do with this car and the ECUTek software.

Im pumped as well!

I wasn't always a tuner so I share everyone's concerns.

The next question is when will it be ready for shipping?

Still waiting. I also looked, and I actually don't see a target A/F ratio table....

Can't wait for tuning options i want to get the turbo on already :)

I would more than glad to show you everything in person when I visit Texas in a few weeks.

John

Sounds like a plan! Any idea what day you might be able to stop by?

Not 100% sure..

Still planning trip..

10.9 jesus, that makes my eyes bleed.

Thats a factory Toyota tune for you. They like em rich and safe.

Toyota likes their tunes like I likes my womens!

11:1 is normal, even on a nonturbo engine. They have to keep the cat from overheating at high rpm. Engines with more expensive components can handle higher heat or can reduce exhaust temperatures. This is a $25,000 car. It's not going to use expensive materials, expensive engine architecture, and expensive control strategies.

target AFR has already been logged with an OBD scantool, see top graph. Nobody's logged open/closed loop yet and posted it--a generic scantool can actually read it if set up properly. You also can look at estimated catalyst temperature with a general scantool. Nobody's posted it yet, but I suspect it's around 950C at the limit. If it gets hotter than that, the catalyst will prematurely age. It's not something an owner would notice but it affects in-use emissions testing from the EPA.

Random just noticed your in Norwalk. I will be there for work in July :) Carry on!
