Does the serial number the Power FC ends with 0030?

For the engine check light, since u say nothing wrong with the car, could it be u did not switch off the boost reading from ur FC Commander? Because u may not have the Apexi solenoid to read boost to ur PFC.
As for the unusual idling, it could b due to many reason... Better ask around others workshops.

Check engine light on most likely because boost control option is set to on. On certain models engine will die off, for RB25 it won't.

Erractic idling could be due to your Power FC did not go through idling initialisation learning. You need to reset it, and when you first turn it on, let the car idle 5 minutes without air-cond, then another 5 minutes with air-cond. If this doesn't do the trick, then most probably your AAC valve is dirty and requires cleaning.
