Not passing smog test please help!!!!
Well i sold my 99 GMC and i went to smog it and it failed. Reason for fail was the computer was reset and "no log information on pcm". I pulled my hypertech out and put it back to stock. After i did that i only drove it about 6 miles to and from work. Then i took it down to have it smoged. He said to drive it a couple of days and bring it back. How long does it take for the PCM to start loging informaion? I just went out and drove it about 40-45 miles and i want to take it back this afternoon. What do you guys think?

You need to have the System Readiness Tests completed in the PCM to pass a "smog check"
A "Drive Cycle" will usually get them completed...

If you have EFILive V6, (www.efilive.com) there is much info in the manual on this, too...
