I recently purchased a kit manufactured by Razor and I was wondering if any of you are using an AVC-R boost controller.

Further that question are any of you happening to use the scramble switch on this unit. I know the alky kit has a wire that produces voltage once the pump is funtioning and there is pressure at the pump head. I was thinking on using this as a definitive safety feature. My plan is to leave the boost at levels around 16 - 18 -psi during no alcohol runs. When the alcohol is running, voltage will be sent to the scramble switch on the boost controller. This will allow elevated levels of boost to come on only when the alcohol system is working.

The challenge I am running into is the scramble feature on the boost controller requires a non locking switch. Is there any device I can use that will act as a non locking switch? This would be the ultimate safety feature..

Any advice / suggestions appreciated.
 
I dont understand the "non locking switch". I guess they mean a momentary switch? If so.. then tie a relay off of the pump feedback circuit to trip only when pressure is met to allow high boost.

I need to know if they are looking for a positive going signal or negative going signal to activate the feature.
 
Apexi calls it a momentary switch. The boost controller allows the user to define an amount of time for either elevated or reduced boost at the touch of this switch.

So what I was looking for is an idea for a circuit that would pulse.

To answer your question, the switch goes to ground. I could use a relay connected to the alkyoff Alky wire. The only challenge I am facing right now is the signal would be continuous and I need a momentary signal according to the manual. I called Apexi and asked if the singal was continuous would this cause harm. The person I spoke with really didn't understand.

What are your thoughts? Can a circuit be built to pulse every "so many" seconds? The amount of time I would use would be based on the scramble duration set in the Apexi.

Thanks..
 
boost controller

i think the apexi has the ability to have 2 different boost settings. but if it does u can use the scramble as a negitive control and use your knock detecctor to activate it. so tune for alky and let any regestered knock reduce the boost.
that way 1 you wouldn't need a switch that kept grounding the scramble wire 2 you just need it to regester knock and youd b safe. let me knw i've got that boost controller and i'm getting alky:D
 
Pro Active Vs Reactive

I'll have to look into that and I definitely appreciate the input. The only thing is I am looking for a pro active approach rather than even putting my motor through any unneeded stress. If I can can avoid knock I would like to.

I know there has to be a way to use a circuit to pulse a ground signal at a pre-defined time. I just need to figure out how to build the circuit.

I'll follow up as soon as I find the answer.
