Message I've even seen it on the Motec M4. The Motec allows you to select a higher sampling rate if this occurs. He might want to look into that. Here is undersampling explained... on the graph, the blue false waveform would be the lower RPM the computer switches too. Its easy to understand why if thats what the computer is seeing.
