Manual Electric boost control brain fart
Ok, so im fucken well sick of ebc's. Dont have the patience for them but appreciate how they get the turbo up on spool. I miss being able to flick between high and low boost on the fly without having to pull over, get out the manual, and spend 20 minutes holding left or right buttons down to scroll through a menu thats written in code language and then not even be sure i've done what i wanted to or even actually not fucked the settings.
I just had an opium dream, where i use a dual stage manual boost controller, a three port solenoid, and a pressure switch, where both top and bottom nipples on the WGs are Tee'd into the boost source via the solenoid, so we're getting boost to the top nipple until the pressure switch trips the solenoid, at which point we're getting boost to the lower nipple and the MBC does its job from there.
Could have say a 10psi pressure switch and be able to swich from say 12 - 18psi on the fly having all the response of a well set up EBC!
Thoughts?
Im using an AEM Truboost BTW.

^ Cheers, that was what i was looking at getting. Turn the ***** and flick a switch.
Could have sworn lastphase had the words "better ebc" as a link that went to an amazon page with a sad puppy dog saying the item was cancelled.
In other news, on the Truboost, changing between settings isnt that hard - its the left button lol. I had a play with it yesterday. Turned it off and drove around in the rain off the 7psi springs.
Have to say - amazingly tractable yet fast! Makes me very glad i went with the 1.05 housing on the efr8375. Id love to see how the .91 iwg boys handle wet weather on a minimum of 12-15psi!
Was driving on setting "A" (18psi) for the last few months before switching to setting "b" (16 - i think?) - they were set up on the dyno by the tuner - no appreciable difference - basically wheel spin in every gear in the dry, lol.
Need to see if i can set it to 12psi.

I have had only one EBC since going there back around 1999.
By reading post on these forums about EBCs, and studying literature on the internet, I purchased one that ended up being one of the best ever made. And not hard to learn.
I was lucky because the USAF helped to increase my knowledge of electronics back in 1966.
God Bless the Vietnam WAR, well at least for my education but not for the many people killed on both sides.
The Blitz Dual-SBC Spec R with: (1) real boost feedback control, (2) a switch to select 4 preset boost setting, (3) over boost control settings (4) spoolup control (5) temporary increased boost setting ability, and more. All I ave to do is rotate a switch to 1 through 4 for what boost I want. The original translated manual was bad but luckily someone on another site made a good manual.
Unfortunately the newer models are more difficult since they offer more functions, and the new manuals also suck.

Those Blitz units are quite pricey. I guess you get what you pay for. The truboost isnt too bad- it does what it's supposed to do. The controls could be a bit more intuitive and the buttons a bit more sausage finger friendly. I just resent having to eff around with duty-cycles and trial ad error instead of just setting your target boost and maybe wastegate crack pressure. Surely we have the technology.
Back to the previous discussion, i think there was a misunderstanding - my idea was to use the turbosmart dual stage MBC (or similar), but use a pressure switch activated solenoid to hold the gates shut until the preset amount, at whic point the upper nipples vent to atmosphere and the MBC controls the boost from the lower nipples in the usual fashion.
I was thinking the pressure switch, as long as its set lower than target boost in the low setting, would be enough for high setting as well.
