You just jinxed yourself to multiple failures and hard to find issues!
I think it's a great tool to get while your car is working properly... then if you play with it enough you'll know what's not normal once you have a problem. My hope is that the full version of OBD ScanTech will do a true power balance test. That will give me the information I need to decide when an injector flush is in order. It will also give you stored codes... I discovered that I had a knock sensor code 27 starts ago... so I know that I should keep an eye out for that now. Plus it's just cool
