defeats the purpose IMO. One of the best features is being able to open or close at a stoplight or during a cruise. Thats the "gotcha" effect. The car suddenly becomes silent there... anyone nearby starts thinking, "did the engine shut off? What just happened?" And then your car rips away in deathly silence (I used an OEM exhaust).

Most fun mod I ever did to any car.

Agreed, LOVE the surprise factor. Just cruising around with the cutout closed, the car is whisper quiet....i mean to the point that most would think the car is stone stock, can't even hear the cam. But should something unexpected happen to "come up" as you are cruising......well.....

When I mentioned manual, I was thinking like a cable actuated lever, so that it'd be instant.

Dunno if they even have something like that, but I have electric cut outs on mine.

I noticed the eBay ones open at 1 bar. Can I hook it to a MAC valve and my onboard compressor to open it manually and/or using my Holley EFI?

That should work fine. The ebay boost activated valves I have opened at
about 4psi.

Old thread, but does pwm output stand for power window? I'm having the issue of keeping it all the way closed. And how did you have it apply 10%? I'm an electrical noob.

Pwm....pulse width modulated. I.e. instead of a continuous DC voltage applied to the motor it's a bunch of pulses. My China cutout came with a controller that must have a current sense in it too to kill power if it hits a stop or something. Took me like 4 hours of fitting and grinding to get it to clear the flanges and screws on the cutout to open and close all the way. The set screws are a good indicator if it's opening and closing a full 90 degrees.

Thanks. It closes....it just rattles and backs off just enough to make the car sound absolutely HORRID. I find myself leaving the thing all the way open more than I care to. I prefer quiet over rowdy more often than not. Going to have to see if I can do what you guys did.

Pwm, my standalone ecu has a few generic pwm outputs. I used a solid state relay in the glove box for this. I'd have to look at my wiring, but I'm able to open it, then shut it down, then turn it on and the motor closes with 10%dc. Think similar to an injector, your sending 12v to the motor only 10% of the time, which on a volt meter would read 2v, but since it is 12v amperage doesn't do anything goofy

Someone used to sell a standalone box for this, but they discontinued it. I think it was qtp

Forgive me for saying but this seems overly complex, I bought a QTP unit on Amazon, put positive and negative to it and its been money for two years now.
Doesn't leak or anything.

I couldn't bring myself to pay hundreds of dollars for a motor with a blade on it.....just couldn't do it.

I totally understand, I should be honest too.
The company I worked for gave Amazon cards as rewards for selling stuff so those covered the majority of the cost lol.
Point being, it gets opened and closed every time I drive the car and hasn't given me issue for two years so even though it's a little spendy its worth not having the head ache of a china unit.
Now that I wrote this its gonna go **** up on me the next time I drive the car...****.
