NPB but service engine light on??
NPB but service engine light on?? 11.2 on a 150 shot was the last pass at the track, and drove the car back home no problems at all , the car was normal. Started the car next day and the service light came on. The car still have stock tune, only TR6 plugs. The last pass I put 110 octane fuel on it and that was all that day.
What could it be, just guessing before I take it to scan it? what usually happens, spark plug burnt, or fluids?

He stated that he drove it home from the track and it was fine so I would suspect the plugs are fine.
Just pull the code and post it up, its the easiest way to diagnose your problem.

Does unhooking the battery reset the pcm? I thought you had to pull the ign and batt. fuses under the hood with the key forward to access. for the pcm to reset?

All the unleaded race gas I've seen here is 100 octane, just so you know. You can also clean your o2's w/ some aerosal non-chlorinated brake parts cleaner. Will clean residue of the sensors and evaporate away.
