I do not know how the iVTEC works on the Fit, but on my 98 Prelude VTEC would be activated at 5500 RPM, Wondering if it works the same way in the Fit and at what RPM it engages?
Thanks,

On the road, the Fit's 1.5L SOHC 16-valve 4-cylinder (117hp@6600 rpm, 106lb-ft@4800 rpm, codename L15A7) has been fortified with "real" VTEC, meaning it actually has dual discrete lift profiles that the intake valves follow, and the difference over last year's "mild" VTEC motor (which switched between 3- and 4-valve operation) is immediately noticeable. On paper the differences don't sound like a lot (+8 hp, +1 lb-ft) but the new version of the engine makes noticeably more torque everywhere below 4000 rpms and above about 5500 rpms, and the difference can easily be felt. To multiply this additional thrust, and to further offset the '09 Fit's weight gain, the effective gear ratios of the 5-speed manual transmission are shorter by anywhere from 3 to nearly 8 percent. The Fit's clutch takeup feels better than before, and the shifter action has been improved thanks to a shorter stroke and double-cone carbon synchros. Acceleration feels downright perky in the lower gears, and the engine pulls very nicely to its 6800 rpm redline, including a nice little VTEC "kick" on the way up. At idle, the engine is so quiet and smooth, on a few occasions I was startled to discover that it was actually still running. The one downside is that compared to most Honda 4-bangers, this L15A7 gets a little bit gritty in the mid- and upper reaches of the rev band.

This dyno should give you a good idea of your power from your Fit. Dyno comes from AJ-racing, who compared the dynos before and after installation of their exhaust system.
Ivtec has eliminated the 'pop'. The pop is a flaw not a feature. The new ivtec system smoothes out the power curve and allows for increases in power throughout the powerband and yes ivtec is in the AT.
I've actually found the cam profile transition fairly seamless at around 4000-4500 RPM, apart from the fact that the reves just keep increasing and you have to be quick with the gear change to keep it off the limiter

That's at the crank right? Or does that much HP get to the wheels.?
