is it essential to map an import
 

is it essential to get a fresh import type r or sti mapped for uk fuel, i always run it on v power. just wondering how many people have imported sti and dont have them mapped, i wont be adding any extras to it so will be standard can i get away without mapping any replies would be great help just trying to get a general idea thanks:thumb:

v power will do just fine.

Haroon.

It IS advisable.

But you dont have to.

this is the thing iv been thinkin about it for a while and been advised to, if i was going to do it i would prob end up going down the simtek route with would also get rid of the maf but i cant really justify the cash at the mo just wondering weather it would be ok and not cause any harm as long as i stick to v power

I have run my classic wagon on V power for the past year without any problems. Should be 100RON fuel though as opposed to V Power at 99RON. Octane booster additive at about £4 a tank will raise it to 100.

No, is the simple answer. Use the best fuel you can afford. If the ECU detects any knock it will retard the timing and the car will lose a small amount of power, thus making it safe.

thanks for the replys thats give me the peice of mind i needed:thumb:

not quite true,the scoob ECU seems to struggle in retarding the timing,7D AND Z4 For sure, it has a knock sensor but doesnt work that well.

i wouldnt rely on the knock sensor to retard the timing if knock/pingin was occuring.

but a remap isnt essential on an import is the simple answer

what year is it? alot of people run them not mapped, but if you start to mod it, i think it is best to have it mapped
