diy electronic 2-stage boost controller
okay check out my idea, in all of its ms paint glory-
i think this would be a very cost-effective 2-stage manual boost controller. once again it's off for high boost, on for low boost.

Re: diy electronic 2-stage boost controller
Looks like it may work, you have to be more descriptive of how it will work and what parts are neccesary to make one.
But if you do make one, plase take pictures and do a writeup, dont forget to make a parts list.
Good stuff

Re: diy electronic 2-stage boost controller
i've been planning on making one of these and using uberdata's nitrous script to activate the solenoid at a certain speed or rpm (you can choose either one). i won't be boosted again for about a month though, but i'm sure i'll have one made and tested before then

Re: diy electronic 2-stage boost controller
That's how I'm making mine. I got son solenoids from a teacher who has a ---- load from his RX-7 collection.
I might make a three stage. He gave me two valves, 1 normally open, 1 normally closed.
I don't know I was thinking 6psi for traction, 8psi for daily driven, or 10psi when someone wants to go,
either that or 8,10,12, or just 6 and 10

Re: diy electronic 2-stage boost controller
I'm not gonna say that this is a bad idea, i'll just tell you that i tried the same thing and it didn't work.
One problem with that design is that on a mbc there is a hole on the wastegate side of the controller, (at least on the one i had) and when you set it up like you have it,
when the solenoid is open then all the air flows through it but instead of pushing on the wastegate it goes out the hole on the side of the boost controller.
I tried it many different ways and couldn't get it to work. I was using a solenoid from a civic/crx though so that might have been the problem. I just kinda gave up on it after many failed attempts.
But if you can get it to work let us know the design and what you used.

Re: diy electronic 2-stage boost controller
This is another way i had it setup and still didn't work
With the solenoid closed, the wastegate would see full boost, then with it open, the needle valve would bleed off some boost making the wastegate open later. That was the thinking in it.
