Auto Enginuity Owners

Got a new toy for Christmas, Auto Enginuity scan tool w/the ford bundle. I finally got it to connect to my truck, scan tool part. But my truck didn't throw any codes and i know it should be throwing at least one. I have my ebpv unpluged and my chip, shouldn't both of those throw a code?
Also, what should i monitor with the scan tool to make sure things are all good?

With the Auto Enginuity came with SpeedTracker; dyno, boost, ect....
But i cant get this program to connect to my truck, i tryed what i had to do to the scan tool to connect but it didnt work. Of crouse it connected right up to my dad's 2000. Any suggestions?

The learning curve is pretty steep but it'll get easier with time....so have fun with it.
Once you get to know it...you'll wonder why you didn't have this tool a long time ago.

Keep the laptop battery fully charged. If the laptop quits during a firmware update you will have a can-o-worms on your hands. Don't ask! LOL. I now use an inverter plugged into the cigar lighter.

Do not connect it to a 1996-2003 Merc Villager. This will burn up the OBD connector. Been there done that.
The Ford Escape (1999-2002) may cause bad things too. AE service is the greatest, they replaced the connectors free of charge.

Be sure to check for updates @ AE's website for the firmware and software version too. I had to update mine right out of the box.
The early OBD2 (1995-1997) vehicles are not as sophisticated as the newer ones. The software will have more sensor choices than the PCM is capable of displaying.

Unplugging the EBPV will not set a code, the PCM doesn't monitor the actual valve position. You may not get a code with a chip either....the PCM deletes some stored codes after ?? amount of key cycles or heat cycles.
When doing Cylinder Contribution Test (CCT) the Engine oil temp has to be above 131ºF, IIRC. Maybe it's 141º can't remember.
