2G Electric/wiring! Dimmer switch on electric boost controller? Custom setup

[TheFlashDSM]

Here’s the plan idea
Using a 12v dimmer switch to control boost levels on the go.

I have an electronic boost controller on ecmlink v3 full now.
I found this like if any body wants to chime in and help for a solution if there is one

So you would like to externally control the solenoid for boost pressure by a dimmer switch without a laptop (ECMLink), is that what you want to do?
If so, then what you probably need to use would be a PWM controller instead of a dimmer switch. To use an aftermarket external boost controller would be the easiest, such as GReddy, Apexi, TurboSmart etc etc.

Yes that’s exactly what I want to do! What is a PWM controller

To control pulse width, that's a part of electric boost controller. I recommend to get an aftermarket electric boost controller, everything you need is built in.

okay, so i ran a google search for "diy electronic boost controller" and i have found some good stuff. maybe i can make something more affordable for an electronic variable boost controller, all other options are stupid expensive.

If you were handy you could come up with a circuit using a 555 ic timer and a solid state relay to create a variable oscillator circuit with the dimmer switch as the input to the timer chip, that would create a frequency based input to the boost control solenoid and the frequency would vary depending on the dimmer switch value.

okay that sounds very complex but i will do some research on what your talking about and try to make some type of solution, and report back

okay so i came across this on emclinks wiki, can we work off of this to make something?

Technical details​

The ECU's WGS output is fixed at 17hz (period of 0.06 seconds).
A “duty cycle” here refers to how much of each 0.06-second period is considered “active” versus “deactive”. A duty cycle (DC) of 100%, for example, just means the output is always active (tied to ground). Likewise, a DC of 0% just means it's always deactive (the output is floating).
Values between these two extremes indicate how long the output is held active before being deactivated during each 0.06-second interval. A DC of 75%, for example, means the output will be tied to ground (active) for 0.75 * 0.06 = 0.045 seconds and then switched off (deactive) for the remaining 0.015 seconds, then switched on again for 0.045 seconds and switched off again for 0.015 seconds, etc.
This provides a relatively smooth analog approximation to a variable value using an on-off solenoid and a digital output from the ECU. Digital outputs and simple solenoid air valves are much less expensive than analog alternatives and provide reasonable approximation

Lol I know for a fact there’s stuff out there, but I’m more interested in learning to make one, not only for the knowledge but also for Pennie’s on the dollar

If you could its been a while since I've worked with ECLlink but if you could hook up the dimmer switch to an input on the ecu and tell it boost control v voltage then the ECU would output the correct PWM signal.

okay now thats a dope idea!
