I use to get confused with calibrating the speedo with ppk. I always think of it as if the cluster reads higher (100kmh) then the gps (80kmh) then the pulse per kilometer needs to increase so the speedo reading decreases.
Or vise versa, if Speedo reads lower then gps, decreasing the ppk will will increase the Speedo reading.
Yeah, Ive found 2 different options for setting the speedo calibration, the first one is done by getting the vehicle up to 100km/h on a dyno and pressing enter on the tech2. The second one I came across adjusts the pulses for the speedo, the speedo in my VY was set at 5000 pulses, which made it read up around 80 km/h when it was really doing around 60 km/h. I've now changed the pulses from 5000 to 5860 and the speedo now reads the same as the GPS reading which seems fairly accurate..
