The scanning software and digital gauge will only give you a reading from the stock, narrow-band O2 sensor. You need a true wideband sensor setup to read actual A/F for acurate tuning. The narrow-band sensor just tells you rich or lean, not how much.

Is there a way to hook up a wide-band and do it the way I am talking about? I have no dyno's even close to where I live!

not that im aware of, a scanner might be able to tell you the A/F , but i personally wouldnt trust it

It is very easy to make your own FPR adjustable. All you will need is access to a welder.

You can get a wideband setup for your car, but most run in excess of $500. There are a few DIY kits out there compatible with the inexpensive sensor, but you are still looking at spending at least $150 plus the time to assemble the kit.
