If your specific ECU part # is currently supported and in the database then we can tune it. If it is not supported then we would have to wait until Uprev starts unlocking new roms again. Could be a month, could be a year. I have no idea.
There are a ton of ECU's already supported, here's a link to the current list for anyone that wants to check it out.

Obviously the odds are much greater with an older car such as a 2012 than a brand new 2018.
