Resetting Ecu Via Which Fuse?

Hi,

I would like to reset my ECU as I want it to adapt to my driving style quicker (recently bought). I've read that undoing the negative lead on the battery will do it but its a bit awkward to get to, so I'd like to remove the ECU fuse. Which ones do I need to remove? Apparently there are some under the bonnet and maybe one under the glovebox, according to the manual.

Thanks in advance!

    On my FRS it's F26 10A located in the fusebox in the engine bay.

    It has symbols on the cover of an ! mark inside a triangle and a open book if that makes sense.

    Leave it out for an hour or so, longer if you can then pop it back in.

    Is it just that one? Can anyone without an RS confirm? I think fuse box may be slightly different

    In the mk 2.5 handbook the PCM is listed under fuses 30/35/36 for non ST models
