The ECU is under the passenger side footwell, take out ecu, remove cover to see what has been placed in the area shown on the piccy below:-
It will either be a single chip which may be soldered to the board or a 'piggyback' board plugged into a chip holder
Cheers

Pavlo can remap these.

Just had a look. There's a board that's plugged onto the highlighted pins. Board covers the entire area above the 4 square black 'thingies'. Doesn't look like it's soldered in, just plugged in.
Who is Pavlo ??

If you want, you can take it out then reconnect 'JP1' then you will be running on the OE map.
JP1 is a zero resistance link, so you can use link wire to do the job.
click on the fitting instuctions at http://www.scoobyecu.co.uk/ and basically follow them in reverse.
In fact, you don't even have to remove the Prova PCB, just remake the JP1 link and it will run the OE map.

Prova chips are normally mounted direct to the board, but I wouldn't go as far to say they are 'WELL' soldered

Basically, the board is made up of 4x black 'thingies' (excuse my technical ignorance)exactly the same as the ones on the 'original' board, this board os plugged onto the highlighted area as the pic.
The other question is, how do I know this car hasn't already been mapped to UK fuel ???

Prova are a Japaense Tuning firm, so it would be mapped to run on Japanese fuel.
They used to just supply modified chips to plug into ECU. But now they do just that then rebaded the ECU.

If you send me the chips I can read them and decode them.
I already have a Prova Map on my hard drive, so it may well be the same as that (depending on year).
Of all the Jap Maps the Prova appear to be the safest, although still a little bit peaky for UK fuel.
If you then decide to get it changed I probably have something suitable to programme them with. You may not get a perfromance gain but it will be a little safer for UK fuel and the spool up may be slighlty improved.
Other on here are running my maps, supplied about 85 last year totally via ScoobyNet (but packed it in Christmas 2003).

advanced for 98 or 100 octane petrol(Japan premium)
You could do what i am doing in a couple of weeks if you had delta dash (arriving in 2 weeks cuz new USB version being released!
) and decrease ignition timing 1 or 2... from within the car and/or decrease boost! I'm in a similar boat as you as i have a Prova mapped ECU but its on a MY01 STi (bug eye) and it is a very fast chip indeed.
Try out a standard STi and "FEEL THE DIFFERENCE!"
