Remapping an import

[megakid]

Hi,

Beening scanning the web for various cars - most imports - where people have mentioned "Always run on Shell Optimax" - I assume this is because of the increased RON petrol in Japan.

Personally, I dont think I could dedicate myself to Shell (not for any particular reason, just I dont think I've ever stopped at a shell garage in all the time I've had my corsa - I just goto anyone I can see at the time) so I'm guessing there is a way to get it remapped to 97 RON petrol?

If so, would you need any ECU controllers (such as APEXi Power FC)? And if it can be done, how much does this type of remapping cost?

Im hoping it will be a ST205 Celica GT4 - Most of them have some sort of ECU modification/controller in them already but if they didnt - could I still get it remapped (and would it be worth it?).

I dont mind buying 97 RON (Premium) as that's available pretty much everywhere. Would that substitute nicely for Optimax ? or a will it be a little bit too low (ie need remapping)?

what fuel is 97ron? is that super unleaded?

Yes, sainsburies seems to be the cheapest seller of this around here (http://www.petrolprices.com) - my local one does 95 RON (standard unleaded) for 86.9p and 97 RON (premium/super unleaded) for 88.9p.

I even put 97 RON in my corsa due to the pitiful 2p different - I dont notice any performance difference (not really expecting to) but I do get an extra 20+ miles to a tank.
