Would the ECU have compensated for the lower octane and I have nothing to worry about? Any thoughts or comments would be greatly appreciated. Other than this one issue the car is in near perfect condition.

The ECU's and related equipment on the Crossfires (and later cars) compensate for the misuse of the regular gas grade. This is not your 70's cars with the primitive smog equipment that created potential damage to the engines. Remember the knocking that took place, when you tried to turn off the engine, and continued to run for a while, due to poor gas or the wrong grade being used? There is a loss of power, based upon the regular grade of gas.
Buy premium....
