To benefit from the performance gains:

http://www.hondata.com/reflash_06_civicsi.html

Quote:
The K20Z3-06Si reflash lowers the VTEC point to 4500 rpm, advances the cam angle and raises the rev limit to 8600 rpm.

We have implemented a VTEC window from 4500rpm to 5800 rpm.

* Below 4500 rpm the K20Z3 is always on the low cam
* Above 5800 rpm the K20Z3 is always on the high cam
* Between 4500 rpm and 5800 rpm the K20Z3 is on the low cam at part throttle switching to the high cam at full throttle.

This one reflash will work well with a variety of aftermarket performance parts. It will work well with:

* An intake
* Cat-backs (as long as they are less restrictive than stock)
* A race header *
* A combination of intake and race header

(*Note that current race headers eliminate the catalytic converter and will generate a check engine light. This engine check light is for emissions and will not affect the car's performance. Race headers are for offroad use only)

You must have a minimum of an intake or header.

It is not designed to work with a stock 06/07 Civic Si and will lose power between 4500rpm and 5600 rpm if installed.

The 06 Civic employs a mass air flow sensor that automatically adjusts the air-fuel ratio for increases in air flow from intakes and race headers. Race headers will not cause this engine to run lean.

The VTEC switch point on this reflash is very smooth - much smoother than previous reflashes. With a stock air box and race header the switch point is virtually undetectable. For the reduction in VTEC "kick" and aural stimulation, we apologize, but this is the path to maximum power.

Power is gained in the midrange from 4700rpm to 6300 rpm. Power gains above 6500 rpm are negligible, although the higher rev limit will raise average power a little.

As this reflash will work with a combination of aftermarket parts we have two examples of the effect of the same reflash on two 06 Civics. (Both Civics dynoed at about 195 stock HP)



* 4500 rpm VTEC point
* Rev limiter raised to 8600 rpm.
* 15-25 Hp gain midrange
* 15-29 ft lb torque gain midrange

^ you listed 15-25hp gain midrange, it should be torque

and 15-29 ft lb torque should be hp

Sorry I can't answer that, as my car has never been on the track.

hondata has no reflash for the r18 currently.

Dealers
list of dealers who offer hondata products. You'll find most cost about the same price, because it's technically set by hondata.
