Renesis Bridge Port

I would figure the surging idle is from the port job. That's how mine was. Actually both the last two times I've replaced the engine I've gone to a bigger port than before and each time it hunted for idle. If it's the same for you, I believe the tune itself should take care of it, maybe some minor adjustments to the idle screw also (if you have one, not sure how idle adjustments are set up for the RX-8).

Naa, the factory computer for the RX8 is probably one of the best ECUs ever created... the idle only starts surging after driving, or if it gets really hot. Since I got the SSV and VDI fixed, it does it less, and to less of an extreme, so I'm sure that was a lot of the issue.

Going to try setting the idle back to 1200 RPM tonight and see what happens.
