As long as you never remove that solenoid, then it won't ever pop a CEL. Those things can very easily be put out of the vacuum loop. However, to use the stock vacuum solenoid, you'd have to cut the connector and put a resistor or somesuch between the ECU side wires, so it didn't pop a CEL, but still let you control the solenoid itself by wiring the control switch to the VICS solenoid. Generally, this can be done with an RPM switch ala MSD or a VTEC/V-anything controller of some sort. I'm sure you could wire some sort of trimmer inline, too, to act sort of like a relay; Once the trimmer's threshold had been breached, it would trigger a relay that turns the solenoid on... Lots of different ways you can do it, in other words. =)

Yep. MSD is adjustable to 12 preset values in multiples of 200 rpm in a specific range. =)
The normal initialization point is 5250 rpm, FYI.

Yes in theory... but that isn't the "honest" practice. I could have copied the JoeP FCD and just made it cheaper but instead spent 3 months making a "better" one of my own design.... it isn't that big of a deal overall... and depending on this and that MSD may have rights to their design. So it's a tossup.
But yes that could be done. Depending on how my schedule shapes up over time and the demand for a part like this I may design and get PCB's made for such a circuit. Right now it is a little ways out though. So knock yourself out if you like!

Getting a functional idea is one thing... copying is another... so yeah twilightprotege

does someone wanna buy this and test for us??

$45.95 instead of $100 for the msd

do you think it would be hard to install? sounds easy to tune etc
I bet it would be easy as hell. Find the resistance of the solenoid you will be using, diconnect the ecu wires and replace with equal resistance reistor. Take the new box, hook up the power wires to the battery, find the correct input for rpm(i could just check my TT 
), hook the output wire to the solenoid, and bam you're done. Of course this is completely speculation, since I really haven't looked at the system in detail. Depending on how much current the solenoid draws, and how much the rpm switch outputs, you might need an intermediate circuit like a power transistor or realy.

won't work the way you guys are thinking.

It uses a solenoid that controls vacuum to a diagh. that opens/closes vics. If you activate the solenoid at a point that there is no vacuum then you won't have any movement of the vics. Also the pcm may be looking for several things while the vics is activated such as o2 switching, etc.... not really sure, I'm researching this right now.
Depending on how and when you want it to activate using the switch, it may work....but we gotta look into it a little more.
