pc software or ecu trouble?
 

I'm running a 3DV4 with both the V4 and V4.72 software. I use the 4.72 to datalog and the V4 for tuning since it starts up faster and hasn't crashed.

From one day to the next, V4 completely ceased to recognize the connected ecu. 4.72 connects and I'm able to make changes and read vitals but the datalogging no longer works or works very erratically.

Trouble with my laptop or the Wolf? Suggestions?

id wager laptop. make sure the plug is secure in the wolf and the cable is good tho.
