Yes I use openecu on my 54 plate STi , results depend on your mapping ability. I've set mine up for normal unleaded running 1.4 bar mid range and 1.2 at the top end , only other mods are a back box and second cat delete.

If you are considering remapping using openecu then read the openecu and the romraider forums there is alot of very useful info on there.
