You can do AutoVE or AutoMAF with Excel - but correctly filtering the data can be a little tricky - and beyond the Excel abilities of most people. Accurately incorporating real time data from a wide band O2 is another hurdle.

EFILive has an excellent scanner (ScanTool) - it makes data collection, data filtering, and incorporating real time data from a wide band O2 readily understandable for most people.
