Electronic boost controller

[Black05wrx]

So I took my car to CFT for the 4th time since I had them dyno tune it to have them fix my overboosting, knocking, and timing problem. After driving all over Orlando so that Sergio could "fix" the problem, he decided that my only option to keeping my boost in check which in turn would stop the knocking would be to get an EBC. I have been meaning to get one, just never got around to it. He suggested the Greddy Profec-b, but I was looking at the AVC-R since it seems like a better unit. I was wondering if anybody had any experience with these 2 or and other ebc, and which you think would be the best choice. Thanks.

should just go ecutek which controls boost and eliminates all those issues you are having

[Black05wrx]

Well a friend of mine got me a good deal on an AVCR, so that's what I am going to be going with. Is there anything special to using it, or is it plug and play? Anybody want to help me out with it?

its not too hard to wire in. there is alot to setup to make correct. prob at least an hour to just tune it

[byerly0137]

i have the greddy profec b and love it. no problems so far. my friend that belongs to this forum (nofearnick02) has the avcr and that is a really nice unit. i like how you can control boost in each gear.

What all needs to be done to get it working correctly? Also, where did you mount yours and what did you use to mount it? Thanks and sorry for asking so many questions.

Why would you even need an EBC when still on the stock turbo? I'm with Faded, dump the UTEC. Then either get EcuTEK or a Cobb AP.

[Black05wrx]

Well I already bought the ebc, plus I don't have enough money to get new EM. I plan on using the AVC-R in my next car, so it's somewhat an investment for the future. :lol: If I ever do something new to this car, I plan on getting rid of the UTEC and going with Ecutek, just not after I've spent all this money getting the damn UTEC to function somewhat properly. Thanks for all the help, it is greatly appreciated.

If you sell the UTEC then you recoup the money needed for the AP or EcuTEK (thus making it free). Yet you have enough money for an item that your ECU can control. Why even ask...it seems you have all the bases covered. :dunno:

Lat time I checked, used UTECs were not selling for more than $500 or so with the map selector and custom maps. It's not the UTEC that I dislike, because I know that if tuned right it is a very capable product. The problem is that there isn't anyone around here that is that great at tuning it. I guess I will just have to learn from my mistakes. Thanks for the help anyway.

Like you're alluded to, it seems there is more of a problem with the tune than the equipment. So how is an EBC gonna control your overboosting, knocking, and timing problems? What all did Sergio try to do to control the overboost preoblem (as its my opinion that the knocking and timing issues would be directly caused by overboost)?

[Black05wrx]

He had me do multiple pulls on the street in 2nd, 3rd, and 4th and was adjusting something, I don't really know what though to tell you the truth. He showed me the logs when we got back to the shop, and it was showing that once the car overboosted to 18.8psi it would start to knock. He adjusted the MBC that came with the UTEC, then we did the same thing again, and it still was overboosting. Either there is something wrong with my MBC supplied by TurboXS, or for some reason my car isn't responding to the changes in the tuning. Sergio directly suggested an EBC as something that would help out with the overboosting problem. If the AVC-R doesn't help out with the overboosting, I have a friend that is willing to buy it off me for the same price I paid for it, so there will be no loss of money necessarily.

[SnowMann]

It sounds like the Wastgate duty cycles are too high if target boost has been set yet you are still overshooting it. Are you sure he didnt say EBCS (not EBC)? I take it you still have the stock BCS in place?

[Black05wrx]

His exact recommendation was to get the Greddy Profec B Spec 2. I have heard mixed reviews about that unit, which is the reason why I chose the AVC-R. To answer you other question, yes I still have the stock BCS.

[Frankie Figs]

Is it overboosting or creeping? What DP do you have?

[Black05wrx]

I have an Invidia V2 dp.

Edit:
I called my friend and told him to forget about the AVC-R and I am getting my money back today. I am going to sell the UTEC and go for an Ecutek instead. An suggestions on where to get the Ecutek from?

Looks like you just missed the boat for the SS session coming up. Pretty sure youre gonna have to wait till another tuner comes down cause Idk of anyone in the state that does Ecutek. Either that or we're taking a road trip to Georgia. :lol:

Lemme know when you can get my cable back to me.

[Black05wrx]

I know that it is commonly said not to get an MBC for our cars, but what about something like a ball and spring MBC as opposed to the bleeder valve that came with the UTEC? Would this help out at all?

A tuning session is being set up with Scott here in Tampa for March 9th, 10th and 11th...

Anyone have an answer to my question about the ball and spring MBC?

[Frankie Figs]

Anyone have an answer to my question about the ball and spring MBC?

NO. MBC's suck. There is no way to hold the boost. Once the wastegate gets the boost signal it will blow wide open to try to get the boost back where it wants it to be. An EBC will only let the gate see what it needs to see to get the desired boost.

My DSM would drop from 17psi-13psi up top with a ball-spring MBC. I havent got the EBC in the car so I cant say for sure, but people have ran the same turbo at 20psi to redline with an EBC.

Are you talking to me :?

[schoellnasty]

Pretty sure he meant Black05. He has a parting out thread up in Suby F/S.

[Frankie Figs]

oh ok :)

[Black05wrx]

Are you talking to me :?

He was talking to me. That's one of my friends messing around with me. He doesn't even have a Subaru. :lol:

black05 thought u said no to ecutek, least thats what u said earlier today.:-o

I made this thread before I knew I had to part out the car and get rid of it. Sorry for the confusion.

With a WRX it's really best to use the ecu to control boost. They are fine with plenty of boost in the middle, but for ring life, they need to have a boost taper up top...

The ecu with Ecutek, AP, or even Utec with the ABC should EASILY be able to do this...
