0% duty cycle and Stim idle LED is on full, 100% duty cycle is off.
95% I can see is dim and down to about 65% I can see the LED is not full on. Any lower than that and it appears to be full on. This part I think is normal. But the dutycyle numbers seem to be reversed. This will work as far as I can see if I just reverse the values, but it seems something is wrong.
It seems that at 100% there should be full current to the idle valve and that should have max idle RPM with full opening of the idle valve. At 0% one would guess you should have no opening of the idle valve and have base idle settings. Is this logical?
