My Tip for Ecto-win trophy in 2021: when trying to beat time of your friend (or your alt-account) - do it on your FIRST ATTEMPT/LAP! The regular manual uploads no longer work and result in error, only top1000 results get uploaded after finishing time trials (as of October 2021). So your friends time should be in the top1000 leaderboard, preferably in the lower portion of it, for ease of beating. It should be displayed in a small table after choosing class and track. Also when starting the race You should get a notification "Friendname's ghost failed to download". Its all fine as long as you beat his Top1000 score on the first try. Otherwise your own local ghost will be saved and all later attempts in same track and class will be against yourself (message at the start "Yourname ghost failed to download") and trophy will not pop even if you make an improvement. If you fail your first try/lap - pause the game and quit immediately via PS button and NOT the "Finish session". Do not race against your own ghost. If you do not have friends with time in top1000, make an alt account and set a time in the very tail end of that leaderboard. Good luck!
