Engine & Internal - engine help!?

k i know this is a dumb question but..
i was at the track on fri and i launched a little hard and heard a little bang like the engine moved and then my engine light came on right away but nothing is wrong with the car it drives normal and everything. i did put a new clutch in a centerforce dual carbon. and it does have a hard kick
am thinking thesensergot hit or something and is nowon.
i was just wondering if this has happen with anyone or if anyone would know why the engine light is on?

i couldnt find the ECU LEDunder the seat

My mistake. The ECU is located beneath the carpet under the front passenger dash. One of these two diagrams should pertain:
