My ScanGauge works fine because I can hard code ISO instead of CAN. However, I am looking for a traditional reader with a display for troubleshooting.
Everything else I own starts by scanning with different protocols before it tries ISO. This always resets the zero point calibration and my VSC TRAC is disabled as a result. I've been to fix it each time but it is time consuming.
Thanks

I have an early '03 V8 and plugging in a scanner (at least, my cheapo Chinese one) does trip the VSC idiot light then it has to be reset. Easy enough, but a pain in the neck. There's something about many modern OBD2 scanners that just doesn't agree with early Gen4 diagnostic systems.
However, I tried the BlueDriver bluetooth scanner -- i.e. the type that connects to your iphone -- and it didn't trip anything. It's a fair bit more user-friendly and you can just leave it plugged in if you want. There are several other varieties of bluetooth scanners out there too.
