2hrs with no wideband and you're expecting results? try 2 months, that's what i took first time around, every day at lunch, 45mins of logs, every 1000rpm 'wave' to make sure it's settled. then start making PE more and more aggressive so i can tune upper ranges. then playing with transmission settings so it doesn't shift when i'm trying to hold it at higher map/rpm conditions, etc...
it's a PITA, get a 250dollar wideband and be done in few days instead. i wish i did.

 

Yep, mine took about a week of driving everynite. They went from -15 to -17 to -1 and a -2 here and there....
