I know this was asked before, but does the tune fix the dip that we have been seeing?

Here are some pictures from the other day --

All very good questions -

1 - EcuTek is the only factory ECU tuning option right now.

2 - You could visit your local EcuTek dealer and have them tune you on the spot OR (and I suggest this) purchase a STG1 or STG2 tune with the ProECU Cable - leave it or have it tweaked via email.

Currently the EcuTek product is edit only via a ProTuner. As time goes by and any/all bugs are fixed the product will be made available to the end user. This is something that will take a while.

3. That's going to be up to you!

Personally if it was up to me the very first thing I would do is the flash.

My STG1 91 & 93 Octane Flash showed enough gain to make it worth the money.

Next week I will be making a STG2 flash.

4. To flash your car you will need a ProECU Cable from EcuTek. Other cables / software will NOT work. EcuTek's ProECU software only runs on Windows Based computers - or a MacBook running a VM of windows. Install the software and flash away. Flashing currently takes about 2-3 minutes.

5 - Yes you can mod after this. I haven't decided on whats going to happen if someone wants to go from STG1 --> STG2 flash / pricing wise.

I need to tune a STG2 car and see what kind of mapping difference there will be - if any.


I spent over 8 hours on the dyno the other night sorting that out...

I wasnt able to remove the hump.

I was able to make changes to the upper part of the HUMP.

I've made changes to both Inatke & Exhaust cam timing, timing, fueling - nothing worked.

Still have a lot more testing to do next week.

No surprise you weren't able to up the torque in that area, but this ^^^ is good :) Will be very useful for people swapping out their intake/exhaust headers.

Thanks

I had my doubts about tuning out the hump I'm in the same camp as others who feel like it is a tradeoff in order to get the low end torque the car does. Through part swaps and ECU tuning maybe the whole torque curve can be made flatter overall.

While going thru the other 700 maps ecutek has located , I did find a few I want to test ..

John,

Have you been able to identify any transitional phases located in the torque dip, I.E. cam timing, or swaping ignition maps, or the transition from port fuel injection and direct, to only direct?

I would imagine working only the fuel, and ignition timing maps will make it slightly better, but would decrease performance elsewhere (robbing Peter to pay Paul).

That's what I'm looking for...

Thank you so much John,

I appreciate your openess, and commitment to this platform

G

Thanks

You haven't seen nothing yet!

This is only the very beginning.

John

As far as fuel goes, if you read the 2GR-FSE development paper it seems they have identified the ideal DI/port mix at all rpm and load, there are no crude "transitional phases". Cams are fixed lobes, continuous phasing, no crude transitions there either.

The fact that they've played around with stuff there and haven't been able to do anything suggests that it's just lower volumetric efficiency there, which ultimately needs new headers to change. The AFR there is 0.9 equivalence which is ideal for power anyways. I think arghx7 said that when it goes down to 12.5 that's to protect the catalyst.

here you go - [ame="http://www.youtube.com/watch?v=1ARdJDbCuCY"]Visconti Tuned STG1 Toyota FS-86 Teaser - YouTube[/ame]

I like how the video edits out all the charts... meh.

But the car sounds good on the street!

Eck-you-teck? Well I learned something today.

you leaned out the top end... Cheater HaHa

Car picks up good power up top from af change alone.

I figured as much after logging my car, that is why I called you a cheater because I can't do anything about my little top end diesel right now:lol:

How did it take to advancing the timing? I know you mentioned multiple maps?

Yup, fueling, ign timing , intake and exhaust can timing have been drastically changed.

I'm able to pickup power about everywhere. Like I've said before car is awesome on the street.

At this time my STG1 91 & 93 maps are complete.

I'll be working on STG2 stuff later in the week.

I also plan on testing this software out on a turbo car very soon.

John

It wouldn't be Don's turbo car would it?

BTW Looked at your site, where did you get your name from ?

....from me , why? Lol

I mean vtune

Most people call me by my last name Visconti... What was get a Visconti tune slowly turned into vtune. Just stuck I guess

ah its very funny.

I have a Saab TurboX and I use Vtuner (Vermont tuning) and we call it a Vtune as well.

http://vtunersaabs.com/

Just small world I may have to stick with the Vtune name for both cars :thumbup:

That is funny as I am a Saab junkie as well. Got a pretty sweet 88 Spring Time in Sweden Convertible w/ a Evo super 16g etc etc... Basically a convertible with factory SPG package

haha thats awesome. Well I will be in your area from Sunday To Wed May have to swing by and say Hi during the week

Sounds like a plan - ill show you some cool stuff

Jon,

is there separate scaling for the port and direct injectors in EcuTek? Do you have control over when the injectors fire? What have you determined to be the duty cycle at max revs?

I have to check

How much power are you able to gain?

And what header are you going to be tuning with? Please tell me the nameless one.

I'm not allowed to say ;)

Right now the owner just put a agency power header on..

So when can you say?

Not sure. Sry.

such a tease:confused0068:

:(

I cant wait to see the power numbers. I picked this thread up a bit late, so excuse me if its already been mentioned, but can you say if you were able to iron out the torque valley?

better but not completely gone. Jon is still working on it, but adjusting timing and fueling only got him so far. How far? Jon is being prude and won't answer:drool:

Sry guys

Not being a tease - just not allowed to post.

Most of my work has been to make sure the EcuTek software works correctly - so when other shops / tuner pick up the software they dont run into problems.

It's not fair for me to post up power numbers when 10 other shops are begging for the software and don't have it.

Good news is EcuTek has located more maps today and are committed on this platform !

When it comes time for other shops to purchase this software it won't be half-ass.

-John

When can we expect some concrete data ? ETA's

Soon!

Sooooo....since Perrin said EcuTek allowed them to release details.....care releasing yours? :D
