Hondata KPro - Acura RSX 05-06

Description

This is a Hondata modified 2002-2004 RSX ECU (USER SUPPLIED ECU must be sent to Hondata - ECU is not included) and an adapter harness for the 05-06 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.

Compatibility
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. The correct method is here: Hyperlink to: http://www.hondata.com/techk20transmissions.html

Application Notes
- An 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. Also see Tech - K20 Transmissions

Only the following ECUs can be used.
2002-2004 RSX Type S (PRB A03-A08, PRB-305 ECU). Should be used for a Type S
2002-2004 RSX (Base 5 speed) (PND -A0# ECU) Should be used for a Base

The stock 2005-2006 ECU part number PRB-A13 through PRB-A16 has a different microprocessor and cannot have a K-Pro installed.
