I finally got my VTEC working now that I figured out why my speedometer wasn't working (annoying loose wire on the sensor plug that I can't get to work consistently, gotta redo the connection I suppose because I'm getting tired of stopping and jiggling the wire to get it to work), and I can hear the change in sound when VTEC kicks in. I've read that the stock tachometers actually read about 500 rpms below the actual rpms. So my VTEC "howl" starts at around 6000 rpm, which would be around 5500 rpm in reality. Those are not exact numbers because I'm flying thru the gears mostly. However, when I'm doin my usual roaring thru the gears on the backroads thing, I hear VTEC kick in and still have my foot to the floor, but I seemed to have already peaked in the gear as far as speed goes, because I don't see my speedometer really moving much till I shift to the next gear. I suppose there's a really simple explanation for this, but I'm really kinda disappointed that VTEC isn't that big a deal. I have fantastic power up till VTEC kicks in, but I would be shifting before that, or immediately after VTEC kicks in, in order to maximize my times. I suppose this makes sense in some way, but I dunno. Maybe I should get a VTEC controller and make it kick in at a lower rpm, say in the 4,000's.
