Japanese 07 Civic Type R Hondata ECU
Applications
- 2007-2008 K20a Japanese 4 door Civic Type R
This is a plug in, reprogrammed replacement
ECU for the 07
Japanese 4 door Civic Type R. It is not
suitable for any US Civic. This ECU is available
direct only from Hondata's international
dealers. This
is not a K-Pro and is not tunable. This
ECU cannot be used with the FlashPro.
Details
Changes:
- - Speed limiter removed
- - 8700 RPM rev limit
- - VTEC 5000 RPM, (lowered from 5700)
- - VTEC window from 5000-5700
- - Cam angle advanced
- - Fueling altered for intakes and
cat-backs
We have implemented a VTEC window from
5000rpm to 5700 rpm.
- Below 5000 rpm the K20a engine is always
on the low cam
- Above 5700 rpm the K20a engine is always
on the high cam
- Between 5000 rpm and 5700 rpm the K20a
is on the low cam at part throttle switching
to the high cam at full throttle.
The Hondata ECU will work well with a stock
Civic Type R and better if an intake or header
is fitted. It will work well with:
- Cat-backs (as long as they are
less restrictive than stock.
(There are several that are more
restrictive.)
- A race header *
- A combination of intake and race header
Power is gained in the midrange from 5300 rpm
to 6300 rpm. Power gains above 6500 rpm are
small, although the higher rev limit will raise
average power a little.
Japanese Civic Type R - stock
The following dyno chart
displays power and torque before and after
the installation of the Hondata 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. Dyno chart courtesy of
CPL
Racing.
This dyno chart as provided by
Driven Performance Singapore shows an
FD2 Civic. Driven Performance also has a
video of the dyno testing. This car was
also completely stock.
Japanese Civic Type R - with
intake
The Hondata Civic Type R
reflash really shines when combined with an
intake.
The bottom
red line is a
completely stock Civic Type R.
The top
blue line is
the power and torque generated from the
addition of an intake and Hondata Type R
reflash.
There are significant
midrange gains from 4000 to redline. At 5800
RPM the torque increases 17% from 109 to 126
ft-lbs. The additional mid range torque
released by the Hondata type R reflash makes
the Civic much more drivable.
How do I purchase the Group N
ECU?
Contact the closest international Hondata
dealer
to you. Hondata does not sell direct.
How do I remove my ECU?
The ECU is located under a plastic cover to
the right of the battery under the hood. You
will need a 10mm socket. This is what it looks
like - in place and removed from the car.
There are 3 bolts holding the ecu in. You
may find it easier to completely remove the
battery, but you will need to enter the codes
for your radio if you do this. This
video also shows the ECU's removal.
Notes:
Nitrous has not been tested. As ignition
timing has not been significantly altered,
nitrous is as safe (or as dangerous) to run with
the reflash as with a stock ECU.
Aftermarket cams have not been tested.
For consistency in dyno testing we suggest
you follow the
dyno procedure outlined here.
Will this affect my
warranty?
Any increase in RPM limit is at your own
risk. If you suffer engine damage that is
related to excessive revs Honda will not cover
your warranty. Valve-piston contact, which
typically occurs at 10,000 RPM is the result of
a miss-shift.
With regard to aftermarket parts, the law in
the US is that warranty coverage cannot be
denied simply because such parts are present on
the vehicle, or have been used. For more details
read the K series FAQ.
You will need to check the laws for your own
country.
