V555MAC

Hi, I've got a my95 v2 STI which I've fitted a Polar performance ecu chip to ( Z4 ecu ). What fuel are these programmed for?. I've always run the car on 97 ron, but didnt know if the Polar chips require this?.

The reason being is that I live on the west coast of Scotland and the local garage has stopped stocking super unleaded and the nearest garage which does is 33 miles away

Thanks for any help!!

Just get some octane booster and put it in at each fill up cheaper than a 60+ mile roundtrip
