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
- 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.

biggest gains are from 4000 to 6000 RPM with
much smaller gains at the top end of the rev

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.
Can this be used with a
This ECU can be used with the FlashPro, but if
you unlock the FlashPro and
stock, the GroupN ECU will be returned to a
stock US Civic Si ECU. In this state it will not
work in the Euro and Japanese Type R Civics.
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.

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

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
