How exactly does an E Boost Controller work?
 

I've heard that Electronic Boost controllers are far superior than none, but I was wondering how it works exactly. Do all the vac lines run to and from it or... how the f.uck do these things work. I wanna get one, but I wanna know how it works first. Thanks.

I'm sure you've seen enough to know what they are made of, and what the display and controls can do for you.

The advantage of the electronics (aside from that user friendly ---- like settings) is they don't act like your typical bleed type screw boost controller.. meaning they eleminate boost creep (similar to the hallman pro controller).

The main concern is, do you really want to trust your whole setup to a pile of circuits and solnoids?

Sounds like an old man making fun of an engine with an ecu.

"I cant fix them engines i dont understand em. I don't trust them sons of bitches one bit. Damn techonolical quazmanatots of the whatsit. Im stickin to my god damn carb."

lol
Still, my carbed motor has that much electrical stuff init. When the machines take over, Ill get in my car, go to start it and the doors will lock and it'll drive itself of a bridge
Dont ask me how

And EBCs allow you to control boost from inside the car. Some manual ones do aswell, but they dont look near as cool as the Tronic ones

Re:How exactly does an E Boost Controller work?
 

damn,make me sound like a real geezer.

it's not that i don't trust them, but if they do malfunction, you could easily ---- your ---- up... I'm cheap so I'll stick with a hallman pro remote manual boost controller.

Re:How exactly does an E Boost Controller work?
 

boost creep? quadnie, I'm pretty sure boost creep comes from a wastegate that can't flow enough fully open. ;)

I'm not sure what the advantages of running a EBC, but my guess would be, you can controll everything more precisely and from insde the car? and also have traction controll, things like that?

Re:How exactly does an E Boost Controller work?
 

you can have staged boost. difrent presure levels for diffrent gears and rpm levels. there pretty badass but i dont know if i would trust one ether. expecialy like the greedy profec the hks one isint any better id take the profec over the evc anyday.

Re:How exactly does an E Boost Controller work?
 

oh and the hks evc returns your car to stock boost "what your wastegate is set to" if it fucks up or turns off. i think the greedy one does too but if for some reason it just errored and shut your vac line off you would be stuck at full boost and i could see that happening if ther was a power surge or some random thing like that, but you always could and should put an inline fuse on somthing like that.

Re:How exactly does an E Boost Controller work?
 

Ok, so it's electronic and it controls the boost. I know that much. What I'm trying to find out is, It blocks the wastegate from seeing the boost until the desired boost is reached, but then it does what? When it sends a pressure to the wastegate to regulate it at the desired level, how does it do that not knowing that the original spring is set to???? It just sounds really confusing how it could be that precise with everything.

Re:How exactly does an E Boost Controller work?
 

im pretty sure you run a vac line and in paralell with the hose that goes to the waist gate. so it can read how much boost is being put down like a boost guage and it has a valve that opens and shuts just like a manual boost controler exept electronicly controled.

Re:How exactly does an E Boost Controller work?
 

It has a selinoid that is controlled by the boost controller and the boost controller somtimes has its own map sensor and you just run a vac line to it from your manifold.

Re:How exactly does an E Boost Controller work?
 

I've got a blitz SBC electronic boost controller and its awesome. I can adjust the boost within a tenth of a psi, I can adjust the boost on the fly so I don't need to stop the car and pop the hood the adjust the boost, it has a digital peak and hold so you know exactly what max boost was, it has a playback and graphing feature, also it prevents spikes and overboosting and allows you to control and how fast it removes the overboost and holds the preset boost. I can also control the "gain" which is how fast or slow the wategate opens which really helps spool time.


Again, I think an EBC is a good investment and its more reliable and all around more superior to a MBC. I think the Blitz is by far the best EBC out there.

Re:How exactly does an E Boost Controller work?
 

Ok, we're getting there, but the bottom line is that the WG is still in ultimate control of how much boost there really is. So with the EBC, how does it send just the right amount of boost to the WG in order to control the boost at the desired boost level? Especially with not knowing the spring pressure of your factory WG? I understand how it can block the signal, but sending the signal to the WG to give you a desired boost level seems kinda complicated. Just confused on how it does that.

Re:How exactly does an E Boost Controller work?
 

with a boost controller you can't go lower than the wastegate spring pressure, the boost controller works off the precentage above that spring pressure. the boost controller just uses electronic solinoids to control the vaccumm pressure going to that wastegate

Re:How exactly does an E Boost Controller work?
 

I guess it's going to be one of those things I'll have to get and then figure out how it works by doodling with it. Thanks for the help

Re:How exactly does an E Boost Controller work?
 

It works by controlling how much boost the wastegate 'sees.' When you run a line straight from your intake manifold to the Wastegate (w/ 7 lbs spring), it 'sees' boost and begins to open as boost climbs to 7lbs. By the time it reaches 7 lbs, the wastegate is fully open. Actually, it has also let out some air prematurely because that's the physics of a spring.

An EBC lets the wastegate 'see' less boost when there real is more. It's like 'the Hack' fooling the ECU. However, it does it a little differently than changing the voltages.

It think there are two scenarios when using an EBC...Internal Wastegate and External wastegate.

External Wastegate - Hook up the standard boost line to the side nipple on the wastegate. Hook up another boost line to the EBC solenoid and then from the solenoid to the top of the WG. The solenoid then lets boost thru that pushes down on the top of the WG spring, keeping it closed. Based on how much you want to boost, say 10psi...the EBC will allow boost to push down on the spring, until you hit ten lbs (all the way until you hit 10lbs, no premature opening). Now, I think the limitation here is that you cant boost less than your spring, and you cant boost higher than twice your spring.

Internal Wastegate. I'm not sure if internal WG have two nipples like External...but if they dont you would have to run the solenoid in between your boost source and the WG nipple. Now iin this condition, like a MBC, the EBC will bleed off boost until a set pressure limit is accheived and then let the wastegate open up.

Not the best explanation, maybe not all correct...but hopefully that helps a lil.

Re:How exactly does an E Boost Controller work?
 

I was thinking about how it might work like I've heard, and this is the only way I think it could work.

The vac line is hooked to the ebc via the turbo and another to the intake manifold. Now depending on the amount of boost the EBC see's vs. what you are telling it you want, it would have to read boost in your intake manifold and make alot of +/- changes according to the pressures it puts on the wg to keep the desired boost level. I'm sure this is how it works, It's just really hard to explain.
I was more/less confused on how it regulates a boost pressure against a wg spring that is already set to a certain pressure and holding it steady. Say the EBC blocks boost to that 10psi desired pressure, then when it see's 10, it sends ???psi to the wastegate, but in order for the EBC to hold you at 10psi, it would have to send a signal to the wg, and then check back with the IM to make sure the pressure is being held. Then according to what it is seeing at the IM, it would have to +/- the pressure it sends to your wg in order to keep the charge steady.
Am I understanding this correctly?

Re:How exactly does an E Boost Controller work?
 

thats pretty much how it works

Re:How exactly does an E Boost Controller work?
 

Yep, and I believe that some of EBCs even have their own pressure sensor in them as well. THis is how they 'know' what PSI they are at and what to regulate.

Re:How exactly does an E Boost Controller work?
 

Here's a simpler explanation: the EBC solonoid intercepts the vacuum line between your compressor housing and your wastegate. It stays shut until the EBC detects that the boost has reached the desired level (i.e., 15 psi or whatever). It then opens just enough to keep the boost level at the desired setting. It does this by monitoring boost level the entire time.

i've been pricing out EBCs and I can't wait to get one... :D

Re:How exactly does an E Boost Controller work?
 

Ok, I've got it now. I was checking them out on ebay and those bastards are expensive. Even the used hks ones. Is there any of them that I should stay away from? I know that hybrid one looks like a complete peice of ----. I'm talking about getting like an old profec as oppossed to one of the newer profecs? I just want a good basic one, not one that will drive the car for me. ;)

Re:How exactly does an E Boost Controller work?
 

I don't know much about differences between brands/models, but I always keep my eye out for the auctions by the Ebay user "japandy", he is the absolute ----; check out his feedback rating. I've ordered several things from him and they are shipped quick as hell (FROM JAPAN) and are always in awesome shape.
