( [LEASE CONTACT BDK TO PURCHASE ANY HONDATA OR K PRO )
This is a Hondata modified 2002-2004 RSX ECU and an adapter harness for the RSX 05-06. 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 harnesses 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.
