Just like to know when a ECU is listed with a "closed loop" or " open loop " what does this mean? Thanks Gene

Closed loop is when the ECU is looking at the exhaust (oxygen sensors) and adjusting the fuel for best performance.
Open loop is when the ECU is getting its data from a data table in memory.
