Hi Adam, think I found out what the AC/WG switch is - it appears to relate to choosing either internal actuator or external wastegate.

You running an integrated wastegate arent you, so I guess you would use the AC setting - I can only assume it changes the way the gain affects the solenoid output (difference in sensitivity of a external wastegate vs a integrated solenoid).

copied from a subaru sales website:

The Street Spec Boost Controler or SSBC is an entry level, cost effective boost controller that is very user friendly. There are two available boost settings for high and low boost. This boost controller uses as single solenoid and is capable of handling up to 18psi (1.2bar). The SSBC is 1/4 din size and is compatible with internal actuators and external wastegates.

Call blitz in NSW, they are pretty helpful and may have a PDF of the manual in english (they sent a mate one for his SB-ID)

Hi Adam, I think in the case of units like the HKS EVC its a fuzzy logic unit so yeah it learns your boost characteristics with the end goal of reducing spikes, the SSBC isnt a fuzzy logic one.

The gain adjustment is your main way of setting it up to assure its stable - set the gain too high and it will overshoot, too low and it will never make the boost target in the time you want. I guess its just a matter of striking the balance, and doing some test driving with your boost gauge to get it set up right.

On my previous car, the unichip boost controller was very similiar (no fuzzy logic, just wastegate actuation control in relation to MAP) and it was rock solid and got on boost quick and didnt spike, its just a matter of getting the gain level right I think.

Slayer: I have a Unichip boost module on my car. I ditched it. The Unichip couldn't even hold boost up top. It would drop down and the tuners excuse was it was for 'safety'.

I had it retuned at a later date (different tuner) and this time to get around the 'safety' feature I had a cheap bleed valve setup and it held 1.4bar all the way thru.

Now I've ditched the bleed valve and I'm using the Blitz DSBC. Yet to tune it again so I'm running a measly 1 bar (most of the time)

the DSBC doesnt use the same solenoid though, which is the major part im stuck on...

any ideas? its got 2 hoses coming into the solenoid, and 1 coming out the other side

so you dont have to teach it your boost curve, and the boost levels on HI and LO are preset. so once plugged in theres nothing to configure apart from GAIN. correct?

Adam: The DSBC has two places to put the hoses into it. One to the wastegate (internal/external, doesn't matter, as long as it goes to the wastegate) and one to the map/plenum (boost readout if you will). Labelled out and in respectively.

From above it seems like you're saying there are 3 in the SSBC?

The unit to control boost is similar in both the DSBC and SSBC. Which part do you need help with?

the solenoid itself has 3 plugs

im guessing one is the wastegate, one to the plenum, and one to the inlet pipe

seeing as i dont have a hole in the inlet pipe anymore... ill run 2 hoses to the plenum and 1 to the wastegate

however my wastegate looks like this... it has 2 outlets

The solenoid has 3 plugs. I can't help you there. Are there any markings such as in and out to give you a clue? The DSBC only has two. See http://www.mkiv.com/techarticles/blitz_dsbc/ (figure 7)

But your guessing in running 2 hoses to the plenum and 1 to the wastegate makes sense. In the meanwhile I'll ask around, it sounds similar to the AVC-R soleniod (ie 3 pipes).

What kinda wastegate is it? I've always thought you only needed one pressure line to the WG. I'm down on external wastegate experience, perhaps someone can help Adam here.

No labelling on the unit what so ever?

I really can't help and I'd rather not make any educated guesses. Dumb thing to say, but I take it the instructions are useless. I bought my DSBC second hand, lucky for me they have instructions via a Goggle search.

I'm sure someone here has installed a unit like this.

    • Hi all,   anyone know where I can pick one of these up for a reasonable price? I just resprayed my rear trunk due to fuel stain and my new muse spat install.    added a photo for some content 馃ぃ馃憤   thanks 
    • Consider a 35 too...
    • He's right ~ there is no 'magic' with stuff like this ... it is more likely that in the process of looking for the short, the loom/wire 'incidentally' got moved in the process, thus removing the short ~ now, that maybe a wire (in a loom) rubbing against the edge of some grounded metal, that's worn through the insulation, causing the (now intermittent) short to ground. If one wire in a loom has been damaged in this fashion, it's reasonable to presume that other wires beside it may have also be damaged, and now exposed...you can bet the green crusty copper corrosion will start... ...that'd be a pisser, Murphy's Law steps right in as GTS observes...but worse, something like that is easier to find when shorted...ie; unplug bulb and fuse, and put multimeter in continuity mode so you get constant beep, and carefully poke about hoping to find if some movemet of the harness stop the beeping.... ...it's still all a bit Arnie tho' ..It'll be back... 馃槂
    • Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.
    • Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.
