I had to make a 300 mile trip Friday and did some logging.Car is a 2009 Pontiac G8 GT. I hooked up my interface with out the laptop and just logged with the interface. When I got there I download my scan to my laptop.It has spikes going to -100 in the FTC-LTFT-STFT's. So I hooked everything back up with the laptop and it does not do it when logging. So I hooked up just the interface and it does it again.
Below is a scan and CFG. Thanks
