Maybe its already there, dunno, but figured I would throw it out there.
Reason I think a pause button would be good is so that if we get stuck at a long traffic light while scanning and the IAT starts to rise when tuning the VE table, it will start to throw everything off a bit. So if we could get a pause button on both the scanner and block box we could in essence cut those area's out.
Also, if we have a scan one day, and want to continue it the next day with same settings etc, and populate the cells as high as possible this would be another good tool possible... dunno, just throwing it out there
