After adjusting the setting I drive a lengthy amount without the CEL popping up. The only time it comes back on is when I turn the car off and on, which then requires me to clear the codes and thus all the drive cycles are reset (defeats the purpose)

I'll adjust it all the way to the max setting (1 oclock) and see if it makes a difference, but I have a hunch it wont. Anyone have any suggestions or ideas?
You are just using this for one day per year in which you need to get your emissions test done correct ?
