Bully Dog Watch Dog I am lost I just don't understand
My Bully Dog Watch Dog arrived today and I am lost. According to Bully Dog the Watch Dog monitors ECT and EOT as well as Fuel pressure. When I plug this into the OBD2 port none of these parameters are displayed except the ECT. According to others the Scan Gauge 2 will monitor the EOT and the ECT, FICM voltage, trans temp etc. I just don't understand how one can do this and the other can not as they are both reading from the OBD2 port. Don't the gauges get their info from the ECU, so how can one read something the other can not? If anyone can help me I am going to return the Watch Dog and get the Scan Gauge 2 due to the fact that is monitors the paramaters that I am after. Thank you once again for any and all help.
