Boost Controllers
 

1.Which one are you using?
2.Which is the most reliable?
3.Which one do you think offers the most features?
4.Which one would be the best for use on the Interceptor Graddy set up?
5.Which one would be the best for use on the Emanage Graddy set up?


I personally like the features of the A'PEXi AVC Type-R, but I like the style and looks of the HKS units.

I have the Greddy Profec II on my Greddy turboed car right now, but I am removing it & putting the HKS EVC Black unit on there. It has more functions, more reliable, will control boost pressures a bit better (a few times in very cold night weather I have over boosted with the Greddy unit) and offers more detailed tuning ability. Honestly, I have been less than enthralled with my Greddy products lately. Have used HKS products before & they have top quality products, with great customer service. Don't think Greddy has ever heard of customer service.

I had the APEXi unit, but while it offers a host of features, it is quite a bit more complicated to install. Wouldn't suggest it for a novice in his garage.

I would highly recommend against the Profec B Spec II. It's a bitch and a half to get the digital greddy boost controllers to stick. I actually know a few well known tuners who refuse to work on any cars that have those equipped.

I picked up the Greddy Profec B Type S right as it became available. It's exactly like the original analog Greddy Profec B... but with a larger solenoid. Here's some more info on it...

Sorry i can't vote as you didn't make this one an option :p:

Comparison: Boost Controllers
We hit the dyno with six sophisticated electronic controllers and one cheap ball valve

I would agree with that assessment. The digital programming was a pain in the ass, and half the time it didn't do what the instruction said it was supposed to do. I had some boost spikes in cold weather. Went from 7.5 control set to 10 psi in night time weather.

I have the Apexi AVC-R. I would buy it again given the choice.

I think the display looks the best and the form factor makes it easy to place. It offers RPM based boost settings and gear based boost settings. Both of those settings really help to fine tune your boost curve. The gear based boost control is really nice because you can run higher boost for the lower gears were the load on the engine is less, and less boost in the higher gears were the engine is naturally more strained.

I think the E-01 has better datalogging capabilities and provides an analog input to log things like a wideband. But, the E-01 doesn't look as good imo, and isn't as easy to place. It also doesn't give gear based boost control, which is something I really like.

I don't have any experience with the HKS units.

Wow is this thing(GReddy PRofec-B)really that good? it seems to get the best rev.

I would recommend NOT getting the Profec B Spec 2. As soon as I can afford to do so, its coming off.

WOW. look at this thing Blitz SBC i-Color Boost Controller I just might have to get this, hell I wont need to set up a boost gauge and it will monitor my oil temp and pressure. Any thoughts? http://us.st11.yimg.com/store1.yimg...._1888_10536171

I had thought about that too.... it would surely cut some of the cost of my build down, and I wouldn't even have to install a boost gauge!

If you ask around to some of the more well known tuners in the rotary world... alot of them will also point you into this direction as well. Thats why i ended up getting it. Just make sure you get the TYPE-S and not the Spec II

BTW, you can find it cheaper on ebay than on that site i listed. I think i paid $300 for mine (thats including shipping)

I just ordered the Blitz i-COLOR It wasn’t cheap but what the hell has been. The biggest reasons are the reviews are really good for this Boost controller, it’s the perfect size to mount right on the glove box seam using an I Pod bracket, and I will even be able to hide the cable very effectively. I don’t have the additional expense and pain the ass of mounting gouges all over the place cutting and drilling into harnesses and parts of the car. And it looks incredible, the cars interior won’t look like a 777 cockpit. I will let you guys know how it works out as soon as everything is mounted and working.
So far I have
Greddy Kit
HKS SSBV and weld on bong.
Interceptor X
Blitz i-COLOR
still under 5K
All I need now is the exhaust and a sugar mama correct?
Love Dave

Turbo XS exhaust really helped my setup to come alive. Might want to consider it. Just weld on some new tips first and its a great exhuast.

Yeah I was looking at that the 3” one right? How do you like it? What’s wrong whit the way it comes.

Wow $705...yikes ! Looks real nice though. Also, you tend to want the gauges on the outside so you can see them. That is what they are usually for. Hiding in the glove box, or so far over that you really can't see them doesn't make a whole lot of sense. If water & oil temps go up you will never see it, if it is in the glovebox. Try making a custom mount where your storage/lighter area above your shifter is.

No no….the braket comes out between the dash and the glove box, it’s a metal plate that is bent so you can set up an I pod an XM or anything you want to mount with out cutting into the dash. The Boost controller wont be much farter than the radio knobs. I can easily read my XM to go screen from my seat whit out an effort. like these!!
one
two
tree They only cost $18 at best buys

I would prefer to have seperate turbo/oil pressure/water temp gauges for quick visibility... but the fact that this also displays "power and torque, speed and rpm" as well is pretty cool.

I would recommend mounting this into your ash tray lid... should look very sleek down there.

I like that idea a lot; I will see how it fits when it gets here in a couple of days.

Its here….Yey..I’m happier than a gay guy with two ass holes…Now I’m waiting on the Interceptor, Turbo blankets and hose sheaths. The Boost Controller should be here sometime tomorrow and the boost timer sometime this week. I will be ordering the TurboXS race pipe and cat back on the first. Another thing I need to order is the O2 sensor unit for the Interceptor, the only issue I have is that the Boost controller I bought can display AFR’s but it needs, are you ready an O2 O2 sensor unit, which by coincidence is also $450 bucks. I wanted to know if I could use the Interceptor is sending unit to operate the Boost controller display. I don’t want spend $ 900 dollars on O2 sending units. Anyone? :Eyecrazy: Sometime in the next 3 months I will be ordering the lighter flywheel and clutch, is there anything else that I need performance wise other than brakes which I’m getting next month.

You cannot use the Interceptor O2 sensor with your boost controller right out of the box. Its possible you could make it work by appling some signal conditioning. But, I thought about this same thing when I bought my Interceptor O2 sensor. I wanted a gauge that I could always have in the car. But, on the other hand, I'm glad I got the Interceptor version because it allows you to log AFR with all the other engine stats. Water temp, ignition, boost, rpm, air intake temp... It gives a much bigger picture of what's going on and allows you to view it on a full sized screen. You're AFR by itself only tells so much.

Gotcha…… Thanks! I guess I have to start searching about this boost conditioner doohickey

Also if you are going with a midpipe vs. a hi-flow there is a large chance that you will get a CEL (which you might get with the Greddy kit anyways). Not sure if you knew, but the O2 will sense that you have no cat. & trip the light. Everything sounds about good. Unless you are planning to autocross quite a bit, no need to swap out your brakes. Could just go with a set of nice SS brakelines & Hawk or MS pads. 12.8" fronts are more than adequate. Bigger brakes will give you nicer heat fade resistance.

AutoX ? lord no I’m the worst driver ever.

Yeah I don’t want a CEL, I really hate it when lights start going off. I guess I will stick to the high flow then. Another question? I have been searching for two days, is there a do it your self turbo install tread somewhere? How about a boost controller one. I keep looking at the kit it seams it will be pretty damn easy to put this bad boy in. and I’m really glad I’m not messing with that Emanage crap, It seems to me it’s the thing that takes the longest to install.

I have the Turbosmart e-boost2 which is pretty good and easy to use...

Setting up the thing took some time to learn how the thing worked.. But overall the e-boost2 was a really good product...

There is a really long thread about the installation of the kit. It should also include some information about installing the boost controller. When you find it, be prepared to search through quite a a few pages. But it is very helpful as the actual instructions that come with the kit leave a lot of details out, that all the people on the forum have filled in.
