DPS not ready for ECM,, im also waiting for GM-ECM archieve by DPS

Need to get the ecm unlocked by Hptuners

yes i know that is the case but if you edit a gm flash file then flash will it work? i know hptuners is the only one unlocking the e90 but they are changing the chip same as the l5p ecms now they offer a box that will unlock without taking ecm off

I'd love to know the secret process they use
