Just got my aeroforce installed. I bought it used off of here and I never looked at the model number before I installed it. One of the biggest things I was looking forward to using was the annunciator function to warn for KR over 3* but I don't seem to have that function at all. If I go into the menu by holding both buttons down at the same time there is no "setup" or "annunciator" selections available. There is a "shift light" selection but if I click the right button with it highlighted it just goes back to the scan data screen instead of going to the menu to setup the rpm. I have the data speed set to 1 like it says in the instructions too activate the shift light function also. Is there older versions of the aeroforce that don't support the "annunciator" functions?
