What are the capabilities of a Mini VCI? Will I be able to reprogram a Skid Control ECU? If not what would I need to be able to do that without paying a huge amount to a dealership? I have removed the bad Skid Control ECU and ordered a used one to replace it but apparently will need it reprogrammed to work with this car... Any help/ideas would be appreciated...

So far, I have gone to the dealer any time I have wanted an ECU reflashed. They generally charge about an hour of shop time. I don't know if that's what the OP means by "a huge amount", but to me it is worth it just to let it be their problem if anything goes wrong in the reflash and bricks the ECU. I have two different dongles (a Mini VCI and a Tactrix that I spent more money on), but I would be wary of attempting a reflash with either of those, or probably anything other than the ~ $500 DrewTech dongle that Toyota officially supports. If I tried, and the thing errored out early and just refused to start the process, I'd consider that a pretty lucky outcome.
I poked through several of those. I already read some of those in my searches before posting. What am I missing? None of those are answering the question if this will give me capabilities to program a skid control ECU. My guess is that it only allows you to read codes for diagnostics but not program new ECU's otherwise I would guess some post would have stated it does do that. So if that is a correct assumption...what would I need to program a skid control ECU?
First thing I would do is ask a service department if the ecu reflash is possible. If they can't do it the point is mute. Most people end up sourcing the correct part. It is a common problem as used sellers often do not know there is a difference.
So what are the differences in parts if you are saying "source the correct part"? Is there a separate code on ECU's outside part number? Maybe something hidden in the bar code? A mechanic (not a Toyota shop) did tell me the skid control ECU needed replaced but they could not reprogram it in their shop. So my assumption from that amd other things I read suggests it can be. But I could be wrong.
