My SCT X3 handheld lockes up or freezes while I am trying to datalog. Everything starts off fine when I have it plugged into the OBD port, but after about 5 minutes the unit will freeze up. The unit will not even respond so I will have to remove it from the OBD port. I can't even replay the datalog. All updates have been performed on the unit by my tuner so I am at a loss. Any information would be appreciated.
