K-series ECU Options

Ranked in order of Hybrid Racings preference. For questions on all of the options you can create a sup-port ticket at support.hybrid-racing.com or email us at support@hybrid-racing.com

1. Hondata Kpro

If you are utilizing a Kpro you will need to follow the steps outlined in this install guide to set eve-rything up properly.

ECUs that can be Kpro’d and used with the hybrid racing harness.

  • PRB with code number A01-A12 and 305 02-04 RSX manual
  • PND 02-04 Base RSX manual
  • PNF 02-04 Civic Si manual
  • PRC 02-04 JDM Integra Type R manual
  • PPA 02-04 CRV manual
  • PRD 02-04 CTR manual

ECUs that will not work wit the hybrid racing harness

  • PRA 02-04 Civic Type R ( technically possible to have Kpro’d but will not have a wide-band)
  • PRB A13-A16 05-06 RSX

2. US SPEC Stock ECU’s with an HR immobilizer removal unit. You can see this unit on the Hybrid Racing website.

All US spec K-series ECU have a built in immobilizer system. If you want to use a stock ECU you will need to purchase the HR immobilizer removal box. If you have a stock ECU and no HR immobilizer removal box your ECU will not turn on the fuel pump and it will not send a signal to your coil packs. You can use the HR immobilizer box with the following ECU’s

  • PRB with code number A01-A12 and 305 02-04 RSX manual
  • PND 02-04 Base RSX manual
  • PNF 02-04 Civic Si manual
  • PPA 02-04 CRV manual

Please use the ECU that is most suitable for your engine. For example, if you have a K20A2 from an 02-04 RSX it is best if you use a K20A2 PRB ECU!

No other ECU’s will work with the immobilizer box and the Hybrid Racing harness.

3. JDM TYPE R PRC ECU.

If you have access to a JDM Type R ecu with the code PRC you do not need to utilize the HR immobilizer removal box. This ECU does not have the same type of immobilizer. You will still need to ground one wire to kick your fuel pump on as outlined later in the install guide.

4. AEM EMS

If you are utilizing an AEM EMS you will need to defer to there installation manual.
