Ed is correct. Even a carb car could have a Digital 7 (not a 7531) and adjust timing either by time or in each gear. can also pull it out at the hit to prevent tire spin ( not traction control like the 7531 box which has a slew rate rev limiter). All of this control over timing is available to the carbureted cars, as well as the EFI cars, just different ways of doing it. NHRA does need to police the MSDs as it would not be hard to disguise a 7531 as a 7530 box, and I guarantee that you could make a car repeat within several thousandths with one if you were willing to slow it down in the process. The best way to police them would be to have a laptop in tech and plug into everyone's digital box. It will pull up the model number, the cases are so near identical that it would be easy to either swap cases ,or just the decals
