I have been data logging with Tom now for a couple of months and have just now started having issues. I have a 2004 svt. What is happening is anywhere from 10-200 seconds into the data log the log just stops reading or freezes. I have tried everything that i can find to make this work properly but it just won't work. never has any issues starting though. In the past 2 days i have tried to data log at least 40 times and have succeeded only once. Any help would be greatly appreciated.
