KTuner offers a bone stock 05-06 6-speed RSX Type-S PRB ECU or the option to have it prepared for a KTuner ECU board installation. A prepared 05-06 PRB ECU includes the two surface mount pin headers pre-installed (soldered in) and will then require a KTuner ECU board kit to be installed separately by the end-user.

Note: A KTuner conversion harness is required when using an 05-06 PRB ecu into an 02-04 RSX, 03-05 Civic Si, or any K-swapped 88-00 Civic/90-01 Integra (using an 02-04 RSX engine & adapter harness).
