A new day and all is well. I unplugged the Scanguage and started my car and then plugged the Scanguage in and it now reads iso mode. Yesterday I just turned the key to the on position and plugged the Scanguage in. I guess you can't do that even though the manual seems to indicate that you can. Everything seems to work just fine except the FPR, which the manual says works on very few cars. Since I have a HCH the MPG guage is off quite a bit. I went on a 16 mile test drive on flat roads at 50 to 55 miles per hour in 70 degree temps. My trip A showed 57.9 MPG and the Scanguage read 42 MPG. I guess that sort of shows what the IMA and lean burn contribute to improving your mileage. One thing that surprised me at first was watching the MPG guage go down as I coasted to a red light while the cars readout went up. All in all I'm very happy with my new toy.
