Yes, your car will love this - much like Cale's does!

I am just going through your e-mails right now, will be replying shortly.

[Dano]

if your MBC is slow I dont' think this will help.

an MBC should be instant on for boost, no?

Your going to have a few to look through then.. Haha.. As I broke the map in, the car started to do some funky stuff.

[Uranium9v]

would this help in the instance where in colder weather (under 30 degrees) I get boost cut due to cold IAT's?

He's in cali and he creeps towards redline. 91 octane and anything above 21psi don't mix so he has to make due with a slower response to keep top end boost in check.

This sounds like a tune issue. Are you running an OTS map? Cuts are dealt with in the tune.

[SleeperHatch]

I installed everything today...took like 10mins and that's because I have boost lines like a whore has crabs. With the tune I got from Alex and this boost dial spool is waaaaaaay faster and car pulls great it really wants more boost I can feel it!

God damn it...
I've picked one up, but it's going to take a while to get to me hopefully sometime next week

Everyone please hold off on happiness stories until I've gotten mine

Subbed for computer reading and purchase.

[Dmurray06]

Ordered!

[SarcasticOne]

And do I need to cap the soon to be unused port on 3-port ebcs? Or can I just leave it VTA... Only asking cause I can't find the damn cap, so will have to go to a hardware store or similar

Got a horrible feeling I'm going to have to find a cap of some sort...

Leave it VTA that's what im doing

Let's see a log. Also what did you adjust it to?

No, don't VTA the 3rd port or you will create an intake leak. Cap it.

Easiest way to cap a port is to get a 2 inch piece of hose, find a bolt and thread it into the hose. It should be a tight fit and clamp it down then use this to plug the port. Done.

Your is in the mail and since you paid a good amount for shipping it's coming together with the GA using the fastest service. 2-3 business days priority so you should see it early next week.

Yay thanks lex!!!
Will have to head to local hardware store to find screws/hoses...

Would this be a better alternative than 3 port for running an aggressive reverse boost taper?

I hope to hold 350ft-lbs long enough to hit 400hp with my GTX3071 (with meth of course), and need to order everything before I seek a proper tune. I do like the load tune idea though given the weather fluctuations I see

[Lex]

They will both work.

The 3 port is less flexible in the sense that it is more sensitive to weather and part changes on the car. The OEM dynamics tables have to be altered a lot. Full load tuning is also not going to happen on the 3 port without A LOT of work. However tuners will be most familiar with the 3 port.

The boost dial is a little cheaper but most importantly it allows you to keep the OEM dynamics pretty much intact. Load tuning is not a problem and neither is boost tuning. It is also a lot more forgiving and flexible to weather and setup changes and less prone to boost spikes or oscillations. The downside is that you do have to do some testing to set the dial and that tuners may not be as familiar with it.

[phate]

Infinitely adjustable, I like it. I've seen a couple setups where, even with the wgdc comps set as low as possible, it would still create boost oscillations. Cranking this down a bit would have given us some greatly needed resolution in the comp tables.

Edited, because restrictor isn't an entirely accurate description.

In my experience bleed style boost control (2 port) is both safer and easier to tune, adjust and control. This is why OEMs use it after all. The interrupt style (3 port) sends pressure waves to the wastegate diaphragm that in a lot of cases cause boost oscillations. Also when you get into higher duty cycles with 3 port a very small changed in WGDC causes very large boost oscillations as you start to space out the pressure spikes to the WG diaphragm. The resolution becomes a lot more limited.

[TiGraySpeed6]

Call me silly if you will, but I think Alex nailed it in the first post- Tuning has come full circle, from loathing the load tuning, and loathing the stock 2 port EBCS, through hybrid boost tuning, to loving the 3 port, to boost tuning as the end all be all, back to hybrid tuning, back to load tuning, and now, back to loving the 2 port.

Full circle indeed, and yet better.

The same classic phrase still applies- The way it should have been from the factory!

Wonderfully entertaining car!

Should have worded that differently... I already have the EBCS, but didn't know if load/hybrid tuning could create the linear boost taper I'm looking for. I knew the consistency benefits, so considered it ordered

As for tuners being more familiar with three port, I have a feeling our E tuners will figure it our pretty quickly...

Of course it can. Just set a flat load line to redline and you will see boost rise to maintain that load/torque curve.

Load is analogous to torque.

[BigRedSpecial]

That actually sounds a hell of a lot easier than modulating boost targets/ duty cycle to try and hit the torque target.

You will definitely want to cap boost doing this though, just about every turbo setup will become very inneficient otherwise. Better on most setups to use timing up top.

hahah

the "circle" is human nature...we can't leave things alone.

the "computing" model is very similar.

from centralized "main frame" computers with dumb terms, to disturbed computing with lots of processing power at the desktop [ and a ton of headaches from users] back to desktop visualization in the data center with blades, etc, and little pizza boxes at the desktop.

good times all around.

[TiGraySpeed6]

Yeah, my office has been there, cost comparisonrd that. Not ready to cough up the $$ for it. State of FL is low budget.

[Rayd]

This thing sounds great Alex!
The tune you have been running for me via the Perrin 3-port is running quite well and is controlling boost great, but I have noticed that high ambient temps really affect spool and torque characteristics I.e about a 400rpm extra lag in spool. Will your product help out in this regard or possibly even make it spool quicker?

The boost dial will need an adjustment to the tune but yes, it will make boost and load control a lot more "weather" friendly and flexible. Your car is very very sensitive to WGDC - as you know we struggled for some time with spikes and oscillations.

Seems to be a non stock turbo/boost controller AUDM thing... Mine has had similar issues, hence ordering one

[SleeperHatch]

Took a 4th gear log tonight with the boost dial. Here it is.

[Mistersix]

Awesome-ness from Stratified.

I want to change my tuning strategy to load because i seem to never get the same results consistently with boost tuning. But using this to eek more boost form the stocker, what about the MAP sensor? Would i need to go to a 3.5bar? Or would i see an improvement from adding this device and load tuning? Improvement as in consistency. And maybe even a little more power?

[Lex]

Awesome Cale. You're hitting some really great airflow and load numbers - it must be cooler than when we tuned you in the fall. Your boost will go to 22psi or so in the summer to maintain those same load levels.

I attached a graph of the load versus boost (notice the boost taper upwards to maintain the load targets) as well as a quick Vdyno. His timing is very low for 91 octane cali gas (9* by redline).

If you move the window in a very high region (turn the dial in the + direction lots) you will get extremely quick spool and it will allow the system overall to reach more boost. However this may or may not be a good thing on a K04.

You can definitely switch to load tuning whether using the Boost Dial or not. The OEM turbo has an inline restrictor so it is like a Boost Dial that is not adjustable.

Yeah I took the log after I got off work last night around 1am so that's probably why. Everything looks and feels great for sure though. Can't wait to get the HTP 4" intake and meth to my setup to get as close to 400whp as possible. I still need a nice big Stratified Tuned sticker!

Once you get meth (get a D07 nozzle) a retune will push your power a lot higher since your setup flows really well. A 4" intake is probably not needed and may cause some driveability issues though.

I have some larger decals ... I can send one your way.

Oh ok saves me money then! And ill take whatever you want to send. Also I checked out my fuel pump and internals as well as the relief valve and its all good to go

You have a new boost dial order to AUS! And an email re: boost dial

Thanks again lex!
