1.) The first gauge gave me options for Mazda or Mazdaspeed logo; this one gives neither. However, there are options for GTO, SS, GM, etc.
2.) Check out this knock retard reading: It either gives me some funky reading like this, or its blank (as in a blank screen), or it just repeats the reading from the screen prior. For example, if my AFR is reading 14.6 and I toggle to knock retard, it will say 14.6 solid and won't change.
3.) Some of the other options I've tried don't seem to work either. It will say what it's supposed to be reading, but there won't be anything below; just blankness.
4.) When I shut off the car, the annunciator lights flash 2-3 times, then the gauge turns off pretty quickly....then out of nowhere the gauge boots back up/turns on.....then turns off about 5 seconds later.
