Default Help! I am boosting only .8 bar with EBC

...no matter how I toggle the settings on my EBC, I can't get it to boost pass .8 bar.

Suggestions? Should I reset my ECU?

Thanks.

update: GReddy Profec B Spec II

How the hell can we help if we don't even know what EBC you're using? There are about eleventy billion EBCs out there. You can bump the thread til you're blue in the face but if you don't provide specifics, we can't help much.
Just a shot in the dark, it doesn't seem like you're getting much past wastegate pressure suggesting that you aren't able to bleed much negative pressure off the wastegate line. Make sure your boost control solenoid is functioning.

Well, I just think the problem is something general, not specific to particular brand of EBC. I only had it installed for 2 weeks, and it had been boosting fine until the past 2 days.

The EBC is the new Profec B Spec II unit. So not too many people have experience with it.

Thanks for being so nice about it.

Like I said, sounds like your solenoid isn't bleeding properly. Also, check your wastegate for function, you can grab it and make it flap around, feel for a free range of motion. It could be that your wastegate is being held up by something.

And you might as well post your gain and set settings in case someone out there rocks the same BC.

Also, understand that a lot of us read through hundreds of posts a day that ask for help but don't give us enough details to be effective. I love lending a hand, but if you don't help me, I can't help you. It's like coming here saying, "This electronic gizmo isn't working on my car, how can I fix it?" and that's it, no specifics.

Methinks young Markus needs to have some herbal tea and get laid more...

Henry - do you still have the small restrictor in the hose coming from the turbo compressor outlet nipple? If not, that's your problem.

When you turn the boost controller off, what boost do you run? If you're running the same boost with it off (wastegate spring pressure) as with it on, then Markus is right and the solenoid either isn't bleeding or is installed incorrectly.

I'm pretty sure you don't even need that w/ an EBC.. (can't currently recall)

and its obviously not the Boost control cylenoid as that is being bypassed in his current set up.

It is possible that your boost controller's cylenoid is broken or jammed or something to that affect..

You are running enough over wastegate pressure on the stock turbo to say your bleeding off some air just not a lot.. if this is an aftermarket turbo setup you would need to let us know as if your only running waste gate pressure then it may be something different entirely.

Some you do, some you may not...

That restrictor reduces the total amount of air in the boost control lines.

If a certain solenoid was able to bleed off enough air at 90% duty cycle to allow you to run 17psi with no restrictor, then you can use restrictors to achieve that same 17psi at 70% or 40% duty cycle.

Thanks guys... although I am not quite sure I understand everything being explained here, I'll try to unplug and replug everything around the boost controller setup.

A few more details before I get jumped again:

- I am running on a stock turbo.

- EBC set=20, gain=50, starting boost=15psi, warning=18psi, limiter=99%. These are my lastest setup after consulting a friend of mine with good turbo knowledge. But the boost limit didn't change no matter how I adjust the settings.

- When I first got the unit installed, I was running set=35 and gain=12 and it would continue to boost to 1.1 bar (about 16.6psi?). That was about 2 weeks ago. And it just all of suddent stopped boosting to that setting. That's why I am pondering if the ECU had learned about the potential problem and put the boost in a safer mode.

Thanks again.

If you have an EBC, how is the factory boost controller still able to "put the boost into a safer mode"? Isn't the FBC disconnected?
