The problem with this is that it can be risky if the user doesn't know what he is doing. It's would be possible to write a portion of a ROM into a ROM file that isn't compatible. Which would result in a corrupt file and a possibly nonrecoverable ECU. This is not to say that we will never offer partial writing. But it is something that takes a good amount of time to implement correctly with sufficient safeguards for the end user.
Dont like contradicting anyone but taxtrix\ecuflash does complete rom write of 1280k bytes

tactrix\ecuflash does full erase first then writes complete rom its always 80 sec does not matter if your writing a couple of changes to an existing rom or a complely new rom ie different calid like updating from A01G to D00G. that has completly different structure so partial write would not work.in that case.

So its certianly possible to write a full rom in that timeframe.

Agree partial write would be a dangereous practice with all the different rom types structures, patches ect.
