Available now through us at HA Motorsports is our 05-06 RSX Type-S Hondata K-Pro ECU Package. This package consists of a fully reconditioned 02-04 RSX-S PRB ECU that is specially modified by Hondata to work with the 05-06 RSX Type S electronics, along with a Hondata ECU jumper harness. You will not find a more complete K-pro ECU package for the 05-06 RSX than this package!


  • Fully reconditioned, Acura 02-04 RSX Type S "PRB" ECU
  • Brand new, serialized, Hondata K Pro-4 system.
  • Kmanager software for use with ECU package. Download software for free here: http://www.hondata.com/kmanager.html
  • K Pro system is fully installed into the ECU and tested.
  • Specially modified ECU internal circuitry to allow the 02-04 ECU to work with the 05-06 RSX electrical system.
  • Hondata ECU Jumper harness (to allow the 02-04 ECU to plug into your 05-06 RSX harness).
  • USB cable for connecting the ECU to your laptop for tuning.
  • Hondata accessory harness for connecting optional systems (ex: nitrous control output, boost control, etc.)
  • Pair of Hondata decals.


  • Requires use of an 02-04 RSX Primary oxygen sensor (not included). The 05-06 O2 sensor cannot be used.
  • OBD2 functions will not work and must be left disabled within the software. (will not operate/retrieve diagnostic data with standard obd2 scan tool).
  • The speed sensor spins much faster on the 05-06 transmission than on the 02-04. This ECU is specially modified to recalculate the speed sensor signal, however above 65 mph may cancel cruise control functions intermittently.

Ask a Question
  • this a complete kit? o2 sensor of course but other than that do i do need to get a new key? or anything els other than plug and play?

    If you'd like to be able to run closed loop (recommend), you will need the 02-04 style air/fuel sensor here: Primary O2 Sensor / Air-Fuel Sensor for KPro Applications

    Otherwise, yes this is the complete kit to run Kpro on an 05-06 RSX Type-S.
