As Hondata dealers we can supply the new Hondata Group N reflashed ECU's for the Type-R.
£645.00 incl VAT
The Group N ECU lowers the VTEC point from 5400 to 3800 rpm, advances the cam angle and raises the rev limit to 8600 rpm.
We have implemented a VTEC window from 3800rpm to 5400 rpm.
- Below 3800 rpm the K20Z4 engine is always on the low cam
- Above 5400 rpm the K20Z4 engine is always on the high cam
- Between 3800 rpm and 5400 rpm the K20Z4 is on the low cam at part throttle switching to the high cam at full throttle.
The Group N ECU will work well with on a stock vehicle or on a vehicle with a variety of aftermarket performance parts. It will work well with:
- An intake that has been designed to keep the stock air fuel ratio
- Cat-backs (as long as they are less restrictive than stock. (There are several that are more restrictive.)
- A race header (for off road use only)
- A combination of intake and race header
The 07 Civic Type R 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 the stock switch point. 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 small, although the higher rev limit will raise average power a little.
This ECU will work with a completely stock Civic Type R or one with a combination of performance parts.
2007 Stock Euro Civic Type-R
The following dyno chart displays power and torque before and after the installation of the stock ECU. Intake and exhaust were completely stock. The biggest gains are from 4000 to 6000 RPM with much smaller gains at the top end of the rev range.
