Ok odd ordeal here is last night i took about a 30 minute drive with a 07 chevy malibu 2.2. I had the histogram log open, graph open, pid screen open and tables open. When i was done the Main timing advanced screen was full of logged information. I saved the whole log then i saved the histogram data. I opened the log this morning and i have one box in the main timing advance with any data in it.? I tried closing the log and only opening the histogram data by itself and it is blank. Any ideas?
Here are the config files, log and the timing histogram.
