So wait we order the software, and then how do we connect to the obs1 do we have to buy a tectrix

No it's software / cable package.

EcuTek has their own cable that comes with the software .

Just so I have this straight, as a consumer, I don't need to purchase any kind of cable or software if I don't want to do the tuning myself? Basically I am looking for a tuner who uses ECUTek and they will charge me whatever they choose to do a tune?

Well you'll soon have a few different options.

Currently were setting up EcuTek BRZ ProTuners across the country.

I'll let everyone know when the dealer list is updated on EcuTek's website.

Once the dealers are setup you'll be able to vist them in person and get a tune or purchase a cable and get a etune from them.

Currently the software is only PC based.

This is what it looks like

Guys relax- in 3 months there will be MULTIPLE tuning solutions for this platform...

Lets give EcuTek a fresh chance as this is a new platform with some new hardware/software..

@theshop- Part of getting people to be more open-minded about EcuTek is to perhaps admit at all the mishaps that happened in the past and learn from them, rather than throwing them under the mat like they never happened... Maybe even learn from vividracing and what they have done to do a 180 on their PR.

My $.02

By reporting every mention of their terrible past for deletion? They are doing a far more aggressive job at hiding their past than this...

I would love to see "MULTIPLE tuning solutions for this platform".

Standalone or piggy computers will come and go but the factory ecu is the way to go.

As your know competition normally works in favor of the consumer!

I have been e-mailing John and PMing him and he's been very responsive.

John - Just to be clear, which of the following does ECUTEK give full or partial control over?:

Port Injector mapping
Direct Injector mapping
ignition mapping
Target A/F mapping
VVT mapping (all 4 cams)
Knock response mapping
DTCs
Traction control

Good Question.

Let me find out exactly what EcuTek has done so far.

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.
