EcuTek preparing to release PRO ECU software for BRZ

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

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

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

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.

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
