Sounds great. Do they also have those pills that change water in to gasoline?

Trouble is that tool is OBD 2, it's mainly for older models

There is a newer protocol than OBDII?

I use UltaGauge and I know some use ScanGauge which do what the second link does but you do not need a smartphone for either.

But each only work with OBDII vehicles.

Something I consider advantageous but some may not is when these are plugged into the OBDII port they interfere with some OnStar functions. I state that as a positive as I am the world's foremost defender of OnStar.
