Late to reply but... I't not percentage. It's degrees. As in 0 is fully closed 90 is 90 degrees from closed, or fully opened, but in the tunes 80 is fully opened which is why Roland says it seems to be an arbitrary number. 100 is technically past fully open and 10 degrees shut the other way

Has anyone had any luck getting these to work on a Barra PCM? I've bee fighting PDQ's and duty cycles and saturated sensors and the best I can get is 42.88 degrees indicated with 82.5 degrees commanded. Looks about half open so seems OK. It feels like more of a duty cycle issue if I turn it up to open the throttle more it closes after 42.88 degrees so my next step if I can't figure out a setting is to pull it apart and maybe unwrap the spring 1/2 a turn. Voltages are "ballpark" with lows being lower and highs being higher so I can't just use a resistor to tweak the input/output voltage. PDQ P, I and D gain seem to do bugger all as well...
