I do agree that not being able to make "running changes" is the downside when you compare ecu editor to a dynojet box. Granted, this means it takes more time to tune with the ecu editor. You're able to make more precise map changes with the ecu editor and all of the additional functionality puts it in it's own league. I would assume that all maps are saved to a harddrive as backup which means you can "see" what the tune is for the ECU at any time. If something goes wrong communicating with a dynojet box you would be out of luck too unless you saved the map to your hard drive.
