I've seen an FR-S throw a CEL after a spin on the track. My buddy's S2000 threw a CEL after a spin as well. When you spin, depending on how you react the car can undergo some very strange loads. If you throw the clutch in immediately, you are generally going to be better off. If you don't, the load on the motor can go from very heavy to very light, and back again, at a rate that is not technically possible for the motor under normal driving conditions. This can throw the crank position sensor off or other sensors. Generally you have nothing to worry about. Reset the codes and they likely won't come back. There are cases where permanent damage can occur, like when oil pump nuts back off on e36 M3s, but these cases are rare.
Scan the code, write it down, reset the ECU. It probably won't come back.
