The tuning process is coming along nicely. Tom's has dealt with my idiocy extremely well. For those of you using non-AEM widebands and even some with AEM's, be prepared to do some mathematical calculations in order to get your gauge to match with the datalogger. Even using the settings menu my AEM wasn't reading what the datalogger was and I had to manually set the equation through some trial and error to get it to match up. Good times. All that college math actually paid off for a change. Be patient and listen to Tom. He knows what he is doing.
