I'm working on getting the components together for after my dry cell is finished. I have browsed around this area and can't seem to find a couple of explainations I am puzzled with.
1: I hear narrow and wide-band thrown around a lot, but haven't found an explaination of what it is. I am wondering if my vehicle is narrow or wide(2005 Avalanche 5.3L). I am about to pull the trigger on this EFIE based on a couple posts in here and it's simplicity, and I want to make sure it will fit the bill.
2: Open and closed loop.....Can someone make light of this? Also, how do we know when the ECM is in either?
Please use as few abbreviations as possible with any replies!
