Under the glove box. Remove the plastik panel, and behind that you can see your ecu.

Default Ecu help, please before I shoot this car

2004 civic lx ecu replacement. Removed glove box and I think I see it. Silver vertical box? Easiest way to remove it? Please god help me. Just put 2200 in new top end, altenator, power steering pump and camshaft position sensor. Drove 5 miles and engine light on again. No power and around 2500 rpm feels like rev limiter. Should I just shoot the car? I'm at my wits end
