M102 kat duty cycle
Hello
When i measure duty then all the readings are opposite. Ignition on 30% not 70%, when i adjust richer % goes up and when leaner it goes down. At 2500rpm when warm it rises 10% instead going down. I set it at idle 50% and at 2500rpm 60%, car runs after that great, startup at cold and warm are better than ever. Only at warmup procces it shows what it should, when lambda heats up, its around 35% and rises to 50%. Any ideas? E: If ill switch pins then wold be readouts correct except warmup periood. E2: checked with volts, everything works correct, also warmup, i might have read warmup cycle wrong at first. Found out some multimeters show duty cycle opposite.
