Finally, the mystery box arrived yesterday!
I opened it up, and to my surprise, the VPAC's a lot smaller than I had orginally anticipated. Judging by its size, the device would
easily fit in the small area beneath the cruise control box.

However, the length of wire supplied wasn't enough to reach, and I was too lazy to sit around and extend all the wires last night.
All the necessary parts were included, included T-Taps, the connectors, and even shrink-wrap tubing! Due to my need for quick installs, I opted to use the supplied T-Taps and only needed to solder 4 wires. The installation manual's diagrams were clear and correct (as verified by the Helm's manual). It took me a good hour, just because I'm slow and deliberate when it comes to these things.
Once completed, I took the car for a test drive. I originally set it to ~5K just to make sure everything worked out normally. They did (thank god!). Then I cranked it down to 3K....
Midrange throttle response is noticeably improved. The car doesn't behave apparently difference from idle-3K, only because the blower hasn't hit full boost quite yet, so no change should be expected. The biggest change is seen from ~3.7K - 5K, where you can see the tachometer shoot up much faster a lot earlier in the powerband. It's actually quite nifty!
Luckily for the engine, VTEC is only engaged in the same manner as a stock engine (correct oil pressure, temperature, engine temperature, load, rpm, etc), so light throttle at 4K RPM won't send you spinning your tires into madness. Slamming it at 3K, however, is another story
The torque curve just seems so goddamn smooth from 3k until redline..there's no end in sight--the powerband feels very linear. Being spoiled by a stock VTEC setting, this somewhat sucks, as you subconciously expect an extra 'kick' at 5K, but it's just not there...
The only other difference now is that I no longer get wheelspin in first gear when I mash the throttle (as witnessed in my posted videos).
I now get wheel
hop.
*shrugs*
Not only that, but the unit even has a blue light which activates upon VTEC engagement!
As always, be on the lookout for a dyno by this weekend.
