PRC vs PRB on JDM Integra Type R

I have a 2001 JDM Integra Type R and want to get K-Pro.

Instead of the delay in sending my PRC computer to the US from New Zealand I'm thinking about purchasing a PRB one locally that is already done. Searching seems to show that the PRB with K-Pro will be fine for my car but I wanted to understand if there will be any advantage to sticking to the PRC as the basis of my K-Pro setup.

A PRB ECU will work. The PRB and PRC are the same, apart from the PRB having more inputs and outputs for US emissions.

Slightly offtopic here, but will a K-Pro'd PRD ECU (JDM CTR) work in a JDM Integra Type-R or in a RSX-S? All I know is that all these ECUs (PRB,PRC and PRD) use a wideband lambda.

PRC and PRD are identical.

Are they identical as standard or only when K-Pro'd? So can you use a standard PRD ECU instead of PRC in a DC5 ITR?

Never compared the PRC and PRD factory calibrations - my reference was that 'the PRC and PRD hardware is identical'. I suspect that the PRC and PRD calibrations are very close as the only difference between the vehicles is the exhaust, and that is fairly minor.

Ok, thank you for this clarification!

As it happens I found another dealer here that has loaned me a PRD ecu while my PRC is being sent to get modified.

The PRD feels a little more responsive but this may be due to the resultant ecu reset.
