You can reprogram your 2002-2005 Honda Civic SI ECU and datalog sensors when you install the KPro4 performance parts. This K-Pro makes hardware modifications to your K-Series ECU. Reprogramming your ECU is easy with the accompanying Windows software.
The KPro4 is manufactured by Hondata and is the fourth generation in the KPro lineup. It's more powerful, offers faster upload times and has enhanced onboard datalogging capabilities. Use the live tune or autotune features to make adjustments. The KPro4 comes with Bluetooth integration, dash outputs, advanced engine protection, ethanol sensor input and support for a closed loop wideband.
You get more tasks without ECU slowdown from the KPro4. You can also upload your datalogging and calibrations from your laptop much faster. With live tuning, you can update your main tables in real time, and that means dyno tuning on the go.

Notes about Application
With the KPro4, you get base maps for the following engines: K20A, K20A2, K20A3 Civic SI and the K20A3 RSX base. You can use the 2002- CRV ECU -5-speed PPA –A0# ECU. There is support for the manual K20A3 motor and a secondary intake runner like what is used in the base RSX and CRV.
The K-Pro ECU does not work on automatic vehicles, and you cannot convert the automatic ECU to a manual transmission.
The reverse lock solenoid on the 6-speed transmissions will not work with the PNF, PPA and PND ECUs for 5-speed transmissions.
There is no support for the fuel tank pressure sensor in the Japanese PRD and PRC ECU.
You need an adapter harness if you are using the K-Pro with a 2005-2006 RSX. You also need an 02-04 specially modified ECU must be modified for use. The primary O2 sensor from an 03-04 must be used, as well.
There is a 2-day turnaround time from the time we receive it.
The older ECUs were 2-dimensional tables consisting of engine speed and load. Newer ECUs have three dimensions consisting of speed, load and cam angle. The K-Pro ECU uses three dimensions to give you the most power and efficiency at every cam angle. Tables can be map-traced in real-time.
The main tables are updated in real-time, and the other tables and settings can be uploaded in seconds after you make your changes.
Race vehicles can have their OBDII features disabled. OBDII readiness status and error codes can be datalogged.
The stock JDM and the O2 sensor are wide-band and can read from 11.5:1 up to 30:1 AF ratios.
Dyno tuned base tables for the RSX Type S, RSX Base, Integra Type R and Civic SI engines are supplied.
The ECU can be plugged into your laptop via a USB port, so you do not need any other equipment or external programmer.
Should conditions ever become dangerous for your engine, the KPro4 can intelligently shut down your engine to avoid damage.
