Unscrupulous or just a glitch?
 

So, I've been fighting to get all my readiness codes for smog in Ca. Driven 600 mi each on 2 resets. All 7/8 go ready except SAI. Many of you have told me it's got to be driven. I would think after 600 mi that I would have completed the drive cycle many times. Today, I visit a Indy Porsche guy and he told me he would connect to their Scanner and tell me what didn't go ready. I obliged because I thought maybe he could confirm whether my cheapy HF was accurate or not. After he connects his Hi tech scanner tells me that 5 are not ready. I asked him if he had done a reset as I had confirmed on my scanner before going to him that only 1 SAI was not ready. He said no. Could this actually happen just by connecting his scanner to acquire my data? Do you think I got scammed by these guys? After he scans my engine only 3/8 were ready. I've got to go through the entire process again. Frustrated. Am I over thinking these guys? Please advise.

My cats and O2 sensors were not ready after they put their reader on as well as SAI

He probably reset the codes, maybe by accident. Anyway, it's not how many miles you drive it to get the codes reset. You have to drive it a certain way. See below thread, as I just went thru this myself. There's some helpful links/charts there that show you how to drive it to activate all readiness codes. On many tests, you have to drive with low revs for long stretches at low speed.

If you have a friendly Smog Test place ,they may do a Pretest. They are not allowed to do this on the official Smog equipment now. But they know exactly how to pretest using a SnapOn scanner. Because they are a Smog Test Station they are aware of the gotchas.
If you still have problems , PM me ,tell me which Indie you used and I'll verbally tell you the Smog Station to use.
