boost controller
im in the market for a boost controller. my mbc isnt working correctly. im leaning towards the avcr b/c of its rev specific boost control. is it worth the extra 100-150 dollars more than the profec b. both users please add input

if you get the profec b, make sure you get the spec 1......i have the spec 2 and it is complicated as F$%#&K. the spec 1 is great, two buttons (LOW/HI). I'm sure the spec 2 is a better product but it's only as good as its owner and I don't know how to use all the features on that thing so the extra money i spent is not worth it

Here's the deal -
There's basically 3 types of boost controllers. Manual, simple electronic, and advanced electronic.
IMHO I've never been a fan of manual boost controllers. Yes, they work, but I like being able to adjust the boost without popping the hood and being able to turn the boost way down in inclement weather. Many older electronic boost controllers sell used for the price of a manual.
The more advanced electronic boost controllers (like the AVC-R, Blitz SBC-ID, Greddy E-01) have TONS of functionality, but many people get lost in the options. If you can figure out how to use one of the advanced boost controllers and take advantage of the power, you'll love it. If you're not very tech savvy, you'll hate it, as it will be tricky to get it to do what you want if you're not willing to invest time into studying the manual, playing with the features, testing and dialing it in, etc.
Personally I'm planning on an AVC-R - I had one back in the day on my TurboII and I loved it. I'd really like to use the RPM-specific boost control to smooth out any potential transition spike, which is one of the killer features it has for the FD.

thanks for the info dave. i think ill probably go pick up a ebc, i do get sick of having to pop the hood to make boost changes. i do like the ability of the avcr to possibly control spiking so i think ill try that.

Dale, Turbosmart offers an in cabin manual boost controller. Just so you know. I've been using it for years and I really like the simplicity. It has never let me down.

does the greddy do ok for boost spike? ive looked a little into it, greddy is cheaper obviously, but from what ive read it seems easier to install, compared to the avcr. i havnt had a problem, yet, but if its not gonna help as much if it ever comes up i dont want the thing.

The boost controller will only work within the limits of your wastegate so if you have a dp,mp,cb set up the boost controller won't control the spike because the wastegate can't flow enough air.
I have the HKS EVC 1 and it won't control the boost to the desired 10psi but I can raise the boost no problem. the instruction manuel actually has a disclaimer having to do with boost spiking and states that it will only control within the limits of the wastegate.
So if your car is pretty much stock you can raise the boost with the controller and control the boost but as soon as you mess with the exhaust system taking away the back pressure then you have exceeded the limits of the stock wastegate and now the controller will work within the new limits of the wastegate thus not being able to lower the boost to 10psi but still being able to raise it.
The boost controller when hooked up and off the boost should be at whatever boost pressure your car is making with the mods you have . turn the boost controller on and it will raise the boost from that starting point with low, high, and manuel settings depending which controller you have but won't lower it. and the spike will still be there.
This is how mine works and I have a DP,MP,CB but I have the boost controller stepping motor hooked up to the wastegate and the pre-control actuator so with the controller off I boost 7psi and with it on in low mode turned all the way down it boosts to 14psi which is what the car will do without any boost controller hooked up. so I need to get some restriction in my exhaust to bring the boost level down.

thanks...like i said i dont have any spiking, but i still dont have my dp in. and my thing is i hit 11psi sometimes and i just really want to keep it at 10. i dont know if spiking may become a prob and i dont want any higher boost. i would like to get an ecu & boost controller...i have a few weks till my dp will even get here so i want to get it done. i was gonna port the wastegate just so i dont have to later, but im just gonna wait n see what happens. all the stuff i need costs more than i have atm join the club huh?

If you don't have a midpipe, a boost controller should be able to control boost down to 7-8 psi with no spiking. There is no reason, IMO, to spend the extra money for an AVC-R, when a $300 Profec Type-S is simple to set, reliable, and works great.

I've had three differnet ones and never had any issues with boost spikes. Sounds like you might have had other issues.
