Reflash 06-11 Civic Si –K20Z3

Product Description

Details

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
