look it up on you tube...
I saw a video of somebody using it, and thought it was pretty cool..
But it basically seems like a 3rd preset for boost pressure...
Example:
low:10psi
hi:14 psi
Scramble:20psi...???
not sure if its really worth the money thoe

I saw the boost controller on ebay for something like 400 bucks, and that's not so far off from what you'd pay for a new electronic boost controller. Si I figured I would ask around about it. But here's a side question I just thought about, would this mean I would have to tune the car for the max PSI I would be running? and if I did wouldn't that somehow effect the overall tune of the car?

yeah i would say so....
You cant be tuned for 15, then hit scramble boots to like 20....
Its like having a controlled boost spike...
its equivalent of having a low and high setting on your controller, and switching when you need it..
IMO just get a boost controller and a remote for the steering wheel...

Its a common function on many controllers, not all have a separate button relocation though. I have the EVC IV, and that has it. It also has wires in the back for the optional relocation button, so that you can put it on your steering wheel like above, or wherever else you want to put it.
You need to be tuned for however high you set the scramble mode for. For example, I will be tuned for 20psi or so, normal driving on low boost mode will be 14, high boost mode will be set at 20. Scramble will also be set at 20. (this way my boost will never spike past what i'm tuned for).
The purpose for me is when driving in low boost mode i can hook up well in 1st and 2nd gears, then when i hit 3rd gear, i'll tap the scramble boost mode and i'll get the extra boost of high boost mode for the higher gears where i have traction. Then when I'm done with my pull it will go back to normal low boost mode.
Scramble is also timed, on mine i can set it to last for up to 30 seconds.
Not tuned yet so i haven't dared to touch it. I get my tune on the 18th of may, if you can wait that long i can give you more detail on how it actually feels before you lay out the cash. You don't need to spend that much on the EVC 5 just to get scramble though, i got my EVC 4 for 150 on here. (no relocation button though, i just have to hit a button on the controller itself, i haven't priced the extra button.) I know the apexi avc-r has it, and i'm pretty sure the AEM tru boost has it, not sure about the greddy's, and i think the blitz models have it.

Let me see if I have this straight. Lets say I tune my Fc for 25psi, but I only plan on using the 25psi for say dyno pulls or drag racing. But for daily street driving, and freeway runs I can use the boost controller for say 15 and 20 PSI depending on the situation. But the "Scramble" would give me full power at 25Psi. This sounds like a winner. and a hell of a way to crush some spirits at the track, because just when they think they have me beat. Wham Oh!!

talking head
the term " boost scramble" is actually a play on the English translation
-- it actually refers to "scramble boost" which,, during ww2,,
was the English equivalent to the Japanese terms used by Japanese fighter pilots to describe a timed burst of war emergency power
-- for take offs and combat emergency
( scramble being the British term for emergency take off )
-- English and US and German pilots had their own terms for similar raised boost
-- and where under instruction to use it sparingly,, as it could mean shortened engine life,, and engine oil overtemps
as such,, on Japanese boost controllers,, it refers to a timed period of EXTRA than normal boost setting
( and yes,, sometimes on a remote button like at the steering wheel )

I have sc boost on my AEM tru boost controller as well. I think it was made to be boosted over what it was tuned for hence why it doesn't last a long time. This is fine for something like a 2jz but not for us. I like the idea you guys have of tuning your engine to the scamble boost settings and only using it in spurts. Very rotary-centric thinking.

You want rotary-centric thinking. My wife says I'm spending too much time and money on my car and I need to get my priorities in order because she wants a baby. I told her o.k. right after I buy my new turbocharger. Needless to say that was the wrong answer.
