How are you measuring?

... Red Banana should be in pin #2... Black Banana in pin #3... Mercedes uses inverse duty cycle. This confused me a lot when I first measured duty cycle.

If your doing it the other way (reverse pins) that would make your reading 55% at idle and 64-61% at 2500rpm, or 50% at 2500rpm and 40-35% at idle.
