So as a lot of you know, I was boosting about 13 lbs at WOT. I should not have been able to hit over 6psi. Everybody said that the Greddy Profec-b boost controller will only let you turn boost up. I installed it last night but couldnt drive til this morning. And it DOES let you turn boost down. I hit 7psi and full throttle, as opposed to 13+. It also adjusted a lot on the way to work to get rid of my boost lag. So even when I shift at low rpms, it picks up nicely (but not under boost now ) Feels very stock today, I like it. And when I step on the gas, boost is right there for me. You dont know how much it sucked to drive around at 1/8 throttle or less. If I got close to 1/4, I would be boosting about 4-6psi. Not fun, well it is, but I cant do it reliably. Especially in rush hour, it sucks. I love it today though, and I possibly fixed my ICU from resetting. We'll see how that goes. I need to test something. This morning it reset on me, which I figured it wouldnt, but damn, maybe I will figure it out the next time Im in the car. Last night it stayed like 5 times in a row when I turned the key once, twice, than not on. I wonder if a wire is hooked up to the wrong acc on the ignition. That may possibly cause it. Everything looks to be wired fine now, and its still happening. Any info on the ACC on the ignition. It could be hooked to the wrong one? Would that cause it. Something causes it to suck when I turn the car all the way on, and reset the ICU. Any info would be . Thanks



Peace

Who told you it will not let you turn down boost?


This is so false it's not even close to being true on another planet.


edit: No boost controller will you to set boost lower than the WG resistance.

What wastegate and spring are you running?

2nd.

Like i said in the other thread... you should not have been hitting 13psi ++++@ WOT w/o a method to control boost anyways... unless there was something wrong or you had something preventing pressure from getting to the wastegate until 13+ psi (... a boost controller? )

And ya... you can't boost any lower than the Wastegate spring setting.

100000% fact.

I believe that, cuz I was hitting around 6psi with the boost turned all the way down, which is what I knew would happen. If I turned it up ever so slightly I would hit about 8. Something in TSIs unit musta been f"ed. I love their kit, I hate their electronics. They dont know how to make them, or have crappy people soldering and doing whatnot. I need an Emanage.

The wastegate is set for 6 psi, and I would hit about 13. Their icu/boost controller/turbo timer/fuel control/vacuum/everything else unit is able to go up to 13psi and control boost, as I said before. Its a boost gauge, and its a boost controller, somewhat, just not over the wastegate spring setting (is what Ive been told by every single person with the kit. Cant boost over 6psi w/it?? Doesnt make sense). After that you need a boost controller. I dont know how I was hitting such a high level of boost with a 6psi wastegate spring, turned down to 3psi. As I said before, It was set for certain level of boost, which was between 2-6. I adjusted it at certain times in hopes it would respond. I coulda left it at 0 or 13 and hit the same boost. So I did have control over that. I was being told I wont be able to turn it down from like 13, cuz thats where the wastegate is set.

But believe me, I asked people repeativly, and they said you can run between 0-6lbs with TSIs unit. Not above 6psi, after that, you need a real boost controller. Luckily I got mine for a hundred bucks used, and it works great. Just need some zip ties on a couple spots. Ill get those in a little bit.

Cool man, very cool! Glad its all working out for you bro! Boost is addicting, eh?

Will a TurboXS manual boost controller prevent overboost past 5lbs like the Profec?

Hey 2K1Civic17"Gabe, with the exception of the ICU resetting, having any other problems with running the TSI ICU with your Profec? I'll probably do the same set up if yours is working good. I was going to get eManage first, but I'll go ahead and get the Profec (or TurboXS controller for now) if your system is running good.

I have a manual boost controller. It will boost what you dial in. No needs to worry about overboosting. Just set it to what you want to boost, and never worry about it again. (only way to turn it down is to stop car, get out, pop hood, turn down dial.... thats why people prefer an electronic controller... but the manuals are pretty easy to install and a lot cheaper)

I was driving my car with my boost controller off and my WG spring was allowing me to hit 5.4 psi and then I set my BC to 4 psi and it stayed at 4 psi then to 3 psi and it stayed at 3 psi. My Profec also has a feature that allows you to reduce boost by a certain percentage if you overboost. Well, right before I had it tuned, I had it set for 5 psi and -100%. The tuner ran my car and every time he hit 5 psi then it would go to 0 psi, stay there for awhile and then climb back to five and drop to 0 again all while staying at WOT. From my understanding of how things work, I would think that you would not be able to boost less than the WG spring pressure but my experience seems to indicate otherwise. My tuner was trying to explain it to me but he spoke very broken English ( too bad I don't speak Japanese). I'm not sure if this is just something that can be accomplished with an EBC and a dual port WG or if this was just some freak thing but it seemed to work for me.

Thanks. That's what I needed to hear.

Emanage is the way to go

You need PRESSURE to open the wastegate. If your spring setting was @ 5.4psi, then the least amount of boost in your system you needed to push the wastegate OPEN would be 5.4psi. LESS BOOST would be incapable. Only way that could happen is if you were 1) not WOT 2)boost leak) 3)WG spring !=5.4 psi

Anyone else have a take on this?

You know, I was thinking about this more after I posted and the only way I could see that an EBC could actually turn boost down is if it could vent pressure from the solenoid to atmosphere so the spring wouldn't see the real boost pressure. I don't think they can do that so you're right, the WG spring probably wasn't a 5.4 psi spring.

Anyway, who cares about turning boost down? I wanna turn it UP.

I have a manual boost controller, and do not have to get out of my car to adjust anything. I have the unit in my car, it has the high and low boost settings, plus it prevents boost lag, spiking, or rough acceleration. Lots of goodies on such a simple product. The smooth/sharp setting I think it is. I know sharp is one.

But you dont have to open the hood if you mount that in your car. You should have it in your car, so you can adjust it as you are driving. Thats what the directions say, turn it up as you accelerate to get to where you want.

My spring is set for 9 psi (according to their directions), I was hitting up to 13psi before with TSIs boost controller. It sucked, so now I hit about 7-9. 9 is WOT, 7 is almost WOT. I am chicken sh** to really step on it though. It will lower boost to the wastegate setting. I was told it wouldnt lower it lower than what I was hitting (13), so I was informing y'all when I posted this it does let me turn it down from what I was at.


Oh and eManage is DEFINATELY the way to go. Get eManage and nothing less.

I just got my TurboXS HP manual boost controller in the mail. Still waiting for my eManage to get hear before installing my kit though (dang FedEx had my zip wrong and sent it to Louisiana!).

Heard so much messed up stuff about TSI's ICU, that I just went ahead and got a boost controller, turbo timer, and eManage so I don't have to use the dang thing to begin with.

I am gonna call TSI today and see if they'll ship me ANOTHER ICU. Hopefully it will work this time.

I wish I had that setup. I use TSIs kit for the turbo timer, and fuel, but have to set the fuel up every time I want to drive. its such a pain.
