An excellent option for vehicles with K series engine swaps that would like to be able to run the Hondata Kpro system is our Hondata KPro / Kswap ECU package. This ECU package is ONLY for use on vehicles with K series engine swaps (ie: 88-00 Civic, 90-01 Integra). This will NOT work in any RSX, Civic EP3, etc. By using an alternative (and much less costly) 02-04 RSX Base auto ECU core, we are able to offer a much more affordable Kpro ECU package than when using a PRB ECU. Using the Kpro4 system's analog input capability, this ECU can be used instead of the more expensive PRB ECU by a simple wiring change for the speed sensor along with a setting change within the Kmanager/Kpro software. What wiring change is needed to use this ECU? See the tech guide here


  • Excellent choice for K series engine swaps into other chassis (ie: EG, EK, DC2, etc) when using an 02-04 style engine harness.


  • Fully reconditioned and inspected K Series swap alternative ECU.
  • Brand new, serialized, Hondata K Pro-4 system.
  • K-Pro system is completely installed into ECU and tested.
  • Kmanager software for use with ECU package. Download software for free here:
  • FREE clear ECU cover with Hondata logo for your ECU
  • USB cable for connecting ECU to your laptop
  • Hondata sub-harness for accessory wiring (ex: nitrous outputs, boost control, etc.)
  • Pair of Hondata decals.

    No, for the EP3 you will need the Kpro/PNF package here:


  • Will this work with a k24a2 swap into an 91mr2?

    You will need to use a cable-driven throttle body on the K24A2 engine, and wire the swap to 02-04 RSX specs, then yes this can be used.

  • Will this work with an eg k24a2 swap?

    Yes, as long as you install a cable throttle body (not the K24A2 drive-by-wire throttle body), and you are using a n 02-04 RSX style engine harness.

    This can be used with a 5 speed or 6 speed, but does NOT have reverse lockout.

  • Will this work with an Ek swap k24a2 with a 5speed and 04 rsx type s harness?

    Yes, no problem.  Be sure to follow the instructions for moving the VSS wire.  Thanks!
