Is there any way to tell if my computer has completed a drive cycle? I have had a bunch of problems passing emissions ever since I got Long Tubes with an Off Road Y-Pipe on my 98 Trans Am. I tried getting the O2 codes tuned out but every time I get the car emission tested it comes up as the computer hasn't completed a drive cycle. So is there any way I can tell if the computer is "ready" before I get emissions tested?

The cheapest OBDII scanners tell you if emissions tests pass as well as reading & clearing error codes. I got one for about $60 at Pep Boys. You can also get it read for free at Autozone.

Take a road trip, if the check engine light doesn't come on during it, you're good to go. 
I have the OBDII scanner and it's been a while since I've had to use it. I can't remember if the code shows up on it before the check engine light goes on or not, but I do remember having to drive a ton to get it to reset after my bad cat was replaced.

we have a special scanner here at work that is designed just to see the monitors as they come on line. We have used it several times to get cars through the inspection process. Certian years need certian number of monitors. the box is called nex tech emission mate. there about a 100 bucks.

I have this one:

There are a number of emissions tests - maybe 7, I forget. But for each it tells you if it passes, fails, or is incomplete. If you have some that are incomplete drive the car more and then scan it again.
I also have efilive which will scan and log a ton of cool stuff. But for emissions readiness all you need is a basic scanner.
