Plenty of logging capability in a Grid. I know everyone thinks they are a great way to "cheat" but if laying dots is cheating then you can use plenty of other things besides a grid to do that. Most the EFI controllers out there will data log and can be made to ride dots and repeat as well. The only way around it is gonna be a mandatory rule for something like a 6 or 7al box with no piggy back boxes or any logging data. NHRA actually just amended the rulebook to include things like laptops and ignition/efi tunes to be a random teched item for all classes. It no doubt is happening by racers lots of ways to "hide" programming in the software of any digital style controller.

IMO if I am data logging I prefer racepak stuff. Simple to use and pretty reliable as well. Where they are legal. If a grid is allowed then I see ZERO reason to not allow a racepak
