02-06 DC5 Type R JDM K20A Prc ECU

This is a JDM K20A PRC ECU, Honda part PRB 37820-PRC-013, pulled from a 02-06 DC5 Integra Type R and sold as a plug-and-play unit for that platform's own 6-speed K-series drivetrain. It's a used, JDM-import unit in very good condition, tested and confirmed working rather than a new or remanufactured part.

What this ECU is for

The PRC code ties this ECU to the 6-speed DC5 Type R and EP3 Civic K-series combination, and it's commonly chosen for K-swap projects into other Honda or Acura chassis, in addition to its original DC5 or EP3 application. It's also a known-compatible starting point for aftermarket piggyback tuning such as Hondata KPro or Ktuner, which many K-swap builders add once the engine is running on the stock ECU.

What to check before you order

An ECU is matched to a specific transmission, immobilizer setup and wiring harness, so confirm all three against this PRC-coded unit before ordering rather than assuming any K-series ECU bolts in and runs correctly. If you're swapping a K-series engine into a chassis that didn't originally carry it, check the wiring diagram for your donor engine and this ECU's pinout together, since an engine harness that doesn't line up with the ECU code is a common reason a K-swap won't start or runs with faults even when every individual part is genuine Honda.

Common questions

Is this a new ECU? No, it's a used, tested JDM import described as very good condition.

Will it plug straight into my EP3 or DC5? It's built for that 6-speed K-series combination, so it should match a stock DC5 or EP3 drivetrain; for any other chassis, confirm your harness and transmission against the part number first.

Does it support aftermarket tuning? Yes, it's a common base for Hondata KPro or Ktuner piggyback tuning once installed.
