tool required to tune or flash an ecm on the bench trans modules and all other modules that are on newer truck and cars and if their are several variables what is regarded by most to be the best

I would like to know with an atomized list of the software and the hardware that is required to tune, flash any ecm or trans module along with what would be considered the best device for data logging the vehicle to be tuned for sever day using different octane fuel and such if there are sever options as it relates to the software I would prefer what is currently being regarded as the best. I would like to bench tune any ecm or trans module on manufactures that have the communication protocols protected. for example my 2021 ford 6.7 power stroke was done by a company in Canada because no one left around here will do the tune in fear of the epa Nazi we now are being abused by in America two years ago you could have a truck totally deleted and tuned buy several shops to day the ecm has to be pulled and bench tuned I would like all the parts and pieces to do this myself please help if possible.
