Most of the Chinese Clone Bluetooth OBD2 adapters are pretty sad refresh rate, with the exception of the one BAFX device that I mentioned. I guess you avoided the Chinese clones altogether by getting the scantool.net adapter.

My $150 software is ScanXLPro with GM Enhanced package. I was able to use it in terminal mode to talk to my 4WD TCCM and to display camshaft retard. I thinkit does some ABS and other things as well but have not investigated. My $300 software is the HP Tuner's VCM Scanner only (without the capability for changing tune). It has the capability to do things like injector balance test, crank sensor relearn, and can control transmission, torque converter clutch, and a variety of other things. Of course there seems to be a lot of additional functionality that I have not yet investigated.

I have heard good things about the EFI Live, but no experience with it.

Didn't realize that Tuna was asking about the same hand held scanner that you have. If I remember correctly, your scanner was a handheld that did do a lot. Can't remember if you said it would trip crank relearn procedure but I'm quite sure it could display camshaft retard.

Yikes! I think all this may be above my pay grade.You sure have provided some "food for thought". I'll have to chew on this a bit. The only other thing I can say at the moment is:

My SES light came back on yesterday while climbing a steep grade at about 45 mph, in the rain. So I'm now convinced it is not the fuel blend. Hence, the need for a good scan tool.
Thanks gentlemen!

 

Don't be afraid. If you get a Digital volt/ohm meter and something to monitor the computer system like torque pro or the autoenginuity you can fix a lot of things yourself. Just pay attention to what people like Captain Hook and Swartlkk say to do to diagnose, and ignore the posts where a guess is being made. Captain already tried to get you started correctly in a previous post.

 

How about the Tsb that was realeased yrs ago regarding the random p0300 being related to valve guides binding up under a load????????? Maybe u should try doing a cylinder leak down test.......... this will tell u upfront if u are dealing with a mechanical issue.........or not!!!!!
