Thread: Missing data points on internal datalog.

  1. #1

    Default Missing data points on internal datalog.

    What causes missing data points for everything on an internal datalog? I've read the posts about EMI/RFI and this seems like a different problem, because all of the logged data is dropping points at the same time, at periodic intervals, (about 0.1 seconds of lost points each time). This happens about 20% of the time I record a datalog, and the car runs great otherwise.
