DIC reads: Reduced Engine Power
I was racing an SCCA race this weekend and I spun. I restarted the car and the DIC read "reduced engine power." The engine would not rev at all whether in gear or not. I got back to the pits and nothing appeared wrong. I restarted the engine and all was fine. It was a very hot day and engine oil temp was at about 298 degrees.
Was this a computer glitch or maybe a "self protect" mode?

Just my opinion but I think it went into what you called 'self-protect' mode - how hot was your coolant? I race a bunch (I've gone off the track a bunch too!) but have never seen this at the track. A knock sensor will induce reduced engine power as will incompatibility between pcm and bcm - but neither of those cases sound even remotely close to what you're describing.......

Ok, I do not race,and maybe this has zilch to do with your situation..
But, the one and only time this happened in my car, it was glitch in the fly by wire throttle mechanism.the gas pedal sending unit..
Apparantly, this is a protection feature to prevent wot runaways vettes!
I pulled over and restarted it...no problems since..
Hope this is of some use to someone, if not you.........

All of your replies may apply. Oil temp was about 300. I did put the throttle down to control my spin (It worked as I did a 360 and was pointed where I wanted to go) so maybe the traction control had a role (although I turn off traction control at the start of a session), and maybe my throttle input during the spin caused a "runaway" response from the computer.
Just glad it wasn't something more mechanical and costly.
