In most of the vids I've seen people only turn on the power/accessories. I noticed when doing scans they seem to be faster with the engine running. Is this because everything is receiving more power with the engine running? What is the proper way to apply changes? I wonder if you use an app or code something with the engine running it is more likely to create an issue. I thought there was an OBDeleven mega thread around here but seem to have lost it. I have the Nextgen version and it operates very smoothly with my Pixel 3. Thanks.
