Applicable ECUs: PRB (A01-A12 & 305) / PND (A01-A09) / PNF / PRA / PRC / PRD / PPA (PLEASE SEE NOTES FOR AUTO ECU’S ONLY BEING AVAILABLE FOR K SWAP APPLICATIONS)

Can only be sold to residents of USA and Canada. If you are in Canada extra shipping may be required and lead time can increase.

Application Notes:

Base maps are included only for K20A2, K20A3 (RSX Base), K20A3 (Civic SI) and K20A engines.
The 2002- CRV ECU (5 speed) (PPA -A0# ECU) can be used.
Support for the manual K20A3 engine and the secondary intake runner as used in the base model RSX and CRV. 
The Japanese PRD and PRC ECU do not support a fuel tank pressure sensor required for some US emissions tests, but will likely pass a tailpipe sniffer test if the catalytic converter is in place.
PNF, PPA and PND ECUs for 5 speed transmissions will not operate the reverse lock solenoid on 6 speed transmissions.
The K-Pro ECU will not work on Automatic vehicles.  Automatic ECUs cannot be converted to manual.
To use the K-Pro on a 2005-2006 RSX, an adapter harness is required, an 02-04 specially modified ECU must be modified for used and the primary oxygen sensor from an 03-04 must be used.
Turn around time is usually 2 days from the time it is received.

General Notes:

From previous ECU’s Honda has changed from 2 dimensional tables (engine speed and engine load) to 3 dimensional tables (engine speed, engine load and cam angle). The K-Pro ECU retains these 3 dimensional tables to ensure the engine is running at optimum efficiency and power for every cam angle.
The stock JDM and US O2 sensor is wide band and can read from 11.5:1 to 30:1 A/F ratios.
Most OBDII features may be disabled for race vehicles.
Error codes and the OBDII readiness status may be datalogged.
Base tables are supplied for the RSX Type S, RSX Base, Civic SI and Integra Type R engines. These tables have been dyno tuned.
No external programmer or other equipment is necessary. Just plug the ECU into a laptop via a USB cable.
Tables may be map-traced in real time.
The K-Pro ECU is not real-time updateable, however most changes to tables and settings can be uploaded in 1-2 seconds. 
The K-Pro ECU is a separate product from the s100/s200 line, and will not share the same options (e.g. 3 step) nor software (HondaLogger, RomEditor). All systems are fully programmable by the user. All K-Pro ECU systems include all features (e.g. boost, datalogging).

New 5/25/2024 updated added:

This is a Hondata modified 2002-2004 RSX TYPE-S ECU and an adapter harness for the 05-06 Acura RSX

Hondata makes hardware modifications to the 2002-2004 ECU enable it to work with the different sensors and actuators found on the 2005-2006 ECU. After these modifications, the ECU will not function correctly on a 2002-2004 RSX.

Hondata only sells adapter harness with the modified ECU. An unmodified 02-04 ECU with adapter harness (with or without KPro) will not work on a 05-06 RSX without the internal ECU modifications performed by Hondata.

The 05-06 K-Pro is only certified to work in an 05/06 RSX. Engine swaps using an 05-06 RSX engine and gearbox into another chassis are not supported with the 05/06 K-Pro and adapter harness.

A primary oxygen sensor from the 02-04 RSX or 02-05 Civic Si must be used. The 05-06 RSX O2 sensor will not work.

Some sensors must be disabled to eliminate errors generated by the ECU.

The speed sensor spins about 100 times faster on the 05/06 RSX gearbox as compared to the 02-04 RSX. Above 65-70 MPH cruise control may not function smoothly and may cancel from time to time.
