Post What kind of boost controller for WRX's?

This is my first turbo car, so I was wondering what kind of boost controller would be better for me, I dont motocross, or rally, and I dont want to spend a ton of money, but I know that you get what you pay for. So I am looking for brands, and should I get an electronic, or manual. Thanks.

Electronic Boost Controllers (EBCs) are the ONLY way to go. Full stop.

There are many ebcs available in the market and there's no such thing as the "perfect" one for WRX. There are very simple units (HKS EVC, Blitz DSBC, Greddy Profec, Sard Trigger) and there are sophisticated ones (Apexi AVC-R). If you are after a simple to use EBC, the HKS EVC is a very good choice but if you are after one that's simple and better than the HKS then it's difficult to beat the Blitz DBSC. Experience says the DBSC holds boost more "solid" than the HKS. While Sard Trigger is another popular ebc here in Brunei, sadly I cant comment on its boost holding ability.

The more sophisticated units such as Apexi AVC-R and Blitz SBC-iD interface with the ECU for additional tuning/monitoring features such as Injector Duty cycle.

Greddy Profec B, HKS ECV EZ and Blitz DSBC are all EBC's that are user controlled. Believe prices are near about $3-400

The Greddy Profec A, HKS ECV IV and Blitz SBC-ID are all more automatic, and I believe all claim to have fuzzy logic. These are more in the area o $5-600.

I personally am leaning towards the Blitz SBC-iD since it is the newest one out there, seems to be the most user friendly, and has this nifty hookup to their Power Meter device, which is kinda like a G-Tech, to have even more features. They take a 1 DIN slot combined, which is really cool as well.

JaMa, are you sure the ticking noise isnt coming from the factory solenoid instead ? I once relocated the '98 3-port solenoid to make room for the HKS EVC, and forgotten to refit the rubber damper, the second I started the engine, there was a constant clicking noise until I fitted the rubber mount back.

I have friends who run the DSBC and no issues of solenoid ticking that i know of.

Yep,

Got my Blitz DSBC installed yesterday, and it too, clicks.

It is the dual solenoids that Blitz provides which are making the clicking noise. You might find different results depending upon where you locate the solenoids....

Mine's bolted onto (using 1 of 2 bolt-holes) the cruise control mechanism.

Personally, I don't mind the noise - can't hear it with the CD player going.

Total newbie questions:

What's the relationship between the boost controller & the ECU?

What's the "optimum" upgrade path between the two?

Thanx.

I have the DSBC from BLitz - Paid $439 plus tax for it at a local store, then had JCSports plug it in. Other than some power problems and a slightly annoying solenoid ticking noise, the unit seems to work well and actually has a bost gauge built into it, if you can read it correctly.

I would actually have to say that the unit is flawless now after I messed around with the gain settings. The car holds a very nice 15.5-16.0 psi without any issues and is plain fast as hell. There are also two other settings "P 0-99" and "C 0-99" which I am not sure what they do.

Any ideas? - none of the blitz directions are in english!

The ticking is normal btw - jcsports confirmed this,

So I found this link
http://www.geocities.com/MotorCity/S...bc_manual.html

It is a little bit old, but it describes perfectly how to program the blitz dsbc controller. I used it to set mine and got very good results. From what I understand you dont really need the scramble unless you want a burst of boost right at the limit, which could be very dangerous if not programmed correctly.

Anyway, have a look.
