Ok, I'm in the process of flushing the whole system, therefore while I am doing it I'm also doing some tests. About 5 minutes ago, while I was testing with the vehicle running I got distracted and turned the little dial (ECU) clockwise,however I didn't turned it counterclockwise, the I heard a poof, and now thhe engine line is on, AMD there is a red led on all the time on the ECU, the car starts , however the lights are still on, what did I break now?

 

If performance hasn't been affect, you haven't broken anything. You can always reset the ecu by disconnecting the battery for(I may be wrong on this) 30 seconds.
