Just installed Blitz Dual SBC Spec S on my evo 9. followed the directions step by step. disconnected one of the stock solenoid lines and capped it off, left the electrical harness still plugged in. ran the lines from the acuator and pressure source from the turbo. used a t fitting and sent pressure to the unit itself, which teed off to the blow off valve. started the car up, and at setting 0 which says is factory boost setting, getting only .84 hkPa, which im pretty sure is equivalent to 12.3 psi. totaly confused right now, any input will help

 

Are you saying you teed lines to the turbo AND bov? That means you are trying to use two pressure sources, doesn't it? You should only go to one pressure source - the compressor nipple or bov line.

11-12psi means base wastegate pressure, which just means you haven't hooked it up right (likely) or don't know how to tune (doubtful). It happens all the time...

 

thanks for the input. i figured out i didnt do anything wrong and that the 12psi is the boost controller itself. I called Blitz North America today and was told that the spec S will only get me about 20 psi at 100%. Nowhere on their site does it say anything about less boost.

The Dual Solenoid Boost Controller R (DSBC Spec R) has four programmable boost settings or various levels of boost. This unit features a built-in boost gauge, peak boost display, four different boost settings, boost warning, scramble boost, and a boost limiter safety feature to prevent over-boosting. The DSBC Spec R uses a dual solenoid design for maximum boost response, capable of handling boost up to 2.5 bar (36 psi). The DSBC Spec R is 1/4 Din size and is campatible with internal actuators and external waste-gates. As an entry-level electronic boost controller, the Dual Solenoid Boost Controller S (DSBC Spec S) offers the same functionality as its counterpart DSBC Spec R. The difference between the DSBC Spec R and Spec S is the solenoid design - Spec R uses a "dual solenoid" while the Spec S utilizes a " single solenoid" design.
--quoted right from their site.

it states that the R is capable of 2.5 bar.. the S offers the same functionality as the R, only uses single solenoid design rather than dual. nowhere does it state that it is capable of running about 1.2 bar. very upset with the explanation. only thing left to do is now put it back in the box and try and sell it.
thank you though for replying to the thread

 

Even though they said that, I would be extremely surprised if it really could only hit 20psi. That would just make no sense - there's no reason for them to sell such an expensive thing that only maxes at an Evo's stock boost unless they're just stupid. That description says 36psi on the R and that it's dual solenoid, so they're saying the single solenoid only gives half the boost potential (18psi)? Why do they call it Dual Solenoid if it only uses a single solenoid design? That doesn't make sense...

 

hahaha exactly my thinking. im very confused as to why they would sell an item for 350 dollars and for it to be capable of only holding about 20 pounds which is stock for the evo. im very disappointed with the company and how they describe the product. not to repeat myself again but in the description it states that the S and R hav ehte same functionality, which it clearly does not. i was told on the phone that 20 psi is about all im going to be able to produce from the S at 100% which will ultimately make the solenoid die much quicker.

 

looks like im just gonna go with the greddy profec b or just spend the money and get aem and not have to worry about boost control.

 

Don't think they have AEM for the IXs yet.

Why not just a simple MBC that costs $80 and works flawlessly with no hassle?

 

just an update to this thread .there are a number of us in the uk running 1.6 bar and more on the dsbc spec s no problems.

 

you definatly have it connected wrong...i just installed mine...and at 90% i peaked 1.6 bar = 26 psi.
