As for 7501-13 (minus 7510) they are all tachographed, don't think 7522-7528 have any reason to be as they should only be on X21/22.
I don't think Arriva will be ordering any E400 MMC anytime soon. (What profitable routes can they be put on that aren't already operated by half decent deckers anyway)
7501-21 (minus 7510) are all tachographed, as 7529-33 will be.
