hi lads quick question reading an article regarding mapping of jap sti,s.according to this mapping isnt always necessary on jap sti,s,and it should only be done if running more boost or any performance modifications,that the stock ecu cant handle but the introduction of exhaust and ram air can be altered by the standard ecu.regarding the difference between the jap fuel and irish fuel is alot more complicated than i thought 100 octane to 95 octane isnt that simple because of the altiude and air density, the knock rating of the fuel varies because of the altitude and works out that the fuel burn is alot different .goes very in depth on the subject bascially boils down to theres not that much difference in the two fuels. any feed back would be good.
