Does ECU adapt to and cancel out mods?

[Jon Jon]

Hi

If a stock monaro has a basic mod such as an exhaust fitted from which a small gain of power is seen, would the std ECU compensate and adapt out the performance gains over a period time and return the engine back to its original power. If this is the case, would it also adapt out any gains from a re-map?

Thanks in advance,

Jon

Thanks everyone for your replies. Much appreciated. I had no idea about the existence of STFTs and LTFTs. Very interesting!
