Interesting that they're running more ignition timing in the torque dip from 3600-4000, and less in 3200 & 4400-4600 to lower the spike.

Is that the stock map or have you already bumped up ignition timing to try to take the dip out?

Also noticed the map changes to 400 rpm break points in the torque dip from 3200-4400.

What he said! I would also like to know if those pics are the stock or a modified map?

If you look at my log data this appears to be the stock map, running load along the 0.70 column, and the torque dip happens right as the map is pulling timing. I live at 5500 feet above sea level which is why my car follows the lower load value ( I figured I would answer because I know somebody would ask). At sea level you would progress further along the load axis and it would pull even more timing.

Hey Guys,
My Name is Ben Dagenais, I work at Lachute Performance and my prior job was Tech support for EcuTeK for 8 years.

The work I am doing at the moment is simple but takes ages. I have to confirm all the different maps present in the ECU (maps needed) so that when you present your car to a tuner... he will know that the parameters available for tuning work and are reliable.

I have not started to tune for power as I don't have the understanding of all systems yet.

I will get you some screen shots later tonight!

Ben

This is a stock timing map, but there is more than one...

I am working on understanding which one is used and when!

Ben

so the stock map is the one pulling timing and potentially CREATING the evil torque valley. So if we adjust the timing out, the valley probably, or mostly, goes away.

How are the AVCS controlled? Is it just based on RPM, or RPM and load?

Remember this car utilizes variable timing, so ofcourse there will be more than one timing map, if I had to guess I would state three, with the actual timing being an interpolation between two maps at a time depending on driving conditions.

He's talking about ignition timing.

Both, just think about it. Low load (high manifold vacuum) + overlap = tons of misfires.

It's Subaru software so it is likely an evolution of what you find on say the current software for say an STi. Oversimplifying: there is a basic timing map, and then a map with additional degrees that can be added on top based on a multiplier. The mulitplier is based on long term learning of short term knock sensor activity.

The timing dip is there for a reason, but expecting a bunch of timing advance to add extra torque there safely may be wishful thinking.

Any word on the injection timing logic or the tip-in/wall wetting correction?

So am I, there are multiple ignition timing maps

Bird is the word

:clap:Word

Back on the dyno this morning!

On the contrary, the timing map posted, has the stock tune utilizing more timing in the torque dip.

It seems the engineer's tried to lessen the dip with more ignition timing in the dip, and less timing before and after.

There are a bunch of different timing maps in the ECU

It's only a matter of time before someone posts a dynosheet with-out that nasty dip.

John,
You said that the Pro tuner will be available before the regular end user software? When will the pro tuner software be available? ETA?

I know Hydra is very close to coming up with a solution...

I hope Phil stepped up his game on the hydras. Back in the day the AVCS maps were password protected because no one knew how they worked.

No tuning was done today - but the boys at ecutek were working on some datalog going stuff.

We have very close. When I start posting up my own results you can bet it'll be soon.

Hoping this week.

John

I've worked on a 2004 WRX with an Ecutek and it was atrocious. Hopefully things have changed since then...as I assume they have... and as you have stated. None-the-less I'm more than a bit cautious.

The Hydra I tuned on an 04STi had some quirks, but the software was functional and intuitive. I really don't like it compared to other ECU's I've tuned, but again... maybe their datalogging sw and tuning sw has changed since then.

I'm interested in the ability to control both the intake and exhaust cams with several additional I/O's... PWM drivers, Digital Inputs (read frequency), as well as a low side drivers. Will the ECU have the ability to PIN/ define in the sw the unused sockets for this purpose?

John,
Are you still affiliated with "The Shop"? I'm not sure of the relationship there and it's not stated in your sig.

Thanks for the response

Nope - no longer do any work out of "The Shop"

EcuTek has been working on the ecu for a long time - they already have a lot of stuff done. They have control of cam timing etc.

Once everything is confirmed to be working OK - they will be working on RaceRom Speed Density and all sorts of stuff.

I've said basically everything I can right now.

John

Thank you for the information, best of luck on your personal venture!

I'll keep my eyes peeled.

Very good read with all the posts in here. Looking forward to seeing more of EcuTek soon! Thanks to Visconti for all the info shared!

Thanks

Just walked in the door after a long day...

I did hear some good news today in-regards to BRZ ;)

Tease.

Yup!

today is HP day at Lachute Performance!
I have 8 hours of R&D scheduled on the dyno, over a 1000 parameters available and more than 150 parameters for logging!

EcuTeK has done their homework in getting us a definition of the ECU.

Sweet! Let the tuning begin!!!!

THANK YOU ECUTEK FOR ALL THE HARD WORK DEFINING THE STOCK ROM:party0030:

If you don't mind could you update your thread with the effect tuning has on the torque dip area? Also do you have maps and definitions for the AVCS?

If so would you mind stating if changing the tables have any effect on the torque dip?

Thank you!

G

The stock Rom? Or 15 stock roms ;)

I can't say what they do or do not have BUT if a company like EcuTek works on a ecu for more than 6 months its ok to assume they have the important stuff defined!!!

John

Holy snickies there are 15 variations of this ROM:bow:

I thought tuning the Evo was diffucult due to the different rom variations spanning 3 yrs for the Evo VIII.

Any idea as to why there are so many? Are the Rom's actually different from the toyota, scion, and subaru????

Glad to see EcuTek trying to make inroads in the US market. It got a bit ugly back then but I've always liked the innovation behind the product. The UK and Australia are still big markets for the software.
@john - very nice, tempered responses to some aggressive questioning. Keep it up!

Thanks - working very hard.

A lot of stuff going on today!!!!

That's all I can say - ;)

So are details (Price and Terms) of acquiring ProTuner License private matters?

Or can you, or someone spill the beans publicly?

I would email ecutek

Sales@ecutek.com for details

Thank You

So there are some questions about tunes and cables.

Once the dust is settled I plan on selling STG1 & STG2 Flashs.

With the flash cable they will cost $950 plus shipping. This will allow you to flash one of my staged flashes in the car and data log. No editing. Edit will come but not right now.

If your local and want a custom dyno / road tune - $750 - this does NOT include a cable. ( I do not suggest this )

If your local and want a custom dyno / road tune and want the cable included

$1,100

Some of you might want to wait for other tuning solutions - its understandable... But I promise you these other solutions aren't going to have things ecutek will have to offer.

Great thing about EcuTek BRZ software is its advanced ECU Recovery. If a flash fails or stops no problem - always recoverable- theres custom code in the ecu that ecutek wrote to allow this.

Anyways we are still far away before anything is released .

There are a bunch of ProTuners / Shops that want to get their hands on the software - this will have to happen first.

John = The man.


We put my car on the dyno yesterday and after plenty of precise adjustments car feels GREAT! Its crazy to see what John can do to an all motor car, not to mention the power delivery is much smoother. This was a huge step forward for the platform and hopefully with more hardware we can get maximize the potential of this car.


Thanks again John!

No problem - Let's get that header on and see what we can do !

Ok so a few questions, I've spent some time reading all this and im still kinda fuzzy on the whole thing...
1) Exactly what benefits will come from EcuTek?
2) So i would have to buy the software and licence and do it my self? (in US)
3) Should I do this before or after I get a new exhaust?
4) How hard is it to do this?
5) Can i add mods after installing?
Sorry I'm new to all this...
