    Have to use V-Power for 6 months without using normal unleaded. But if you put normal unleaded in and use your card you start from day 1 again.

    Like Nilz said, You feel special with one :) haha.

    Happy shopper fuel vs v-power is defo night and day. In the summer months the 95 fuel can eat away at 10+% of the power of a turbo charged car.

    Super & V-power will allow for optimised performance in the mapping, when using 95 the knock sensors will detect the early flame front knock (pinking) and the ecu will start to pull the timing back. If there is constant knock the ME7.5 will auto swith the mapping in the ecu to use a lower load request map to limit the pressure build up in the cylinders to reduce the pinking.

    When the engine is tip top condition and running on good 97+ fuel the ecu will use the optimum performance map tables for the fuel, ignition advance & max engine load.

    To see the effect of the fuel changes you can use vcds to log channel 20, 115 and 118 to get a visual picture fo what the fuel is doing to the engine & performance.

    V-power FTW :blackrs4:

    Yeh I got hold of an sps controller from a very nice chap and have set boost to 9 and timing to 7. With a forge fmic, 99 ron fuel and decent cool scottish weather the corrections are within limits.

    If you put 95 ron in your S3 you might as well own a 1.6 you tight wads.

    Does anybody know how long it takes the ECU to detect the higher octain fuel ?
    I have used both super market grade fuel and shell,tesco,bp high octaine options and to be honest the diffrence is far from day and night but is there,
    WHen ever ive taken the car to be mapped or worked on ive always used Vpower. as from the new engine ive only run on it too.
    Just because of what i heard somebody say that rang very true... "you have bought and modded quite an expensive car there... to get the best from it, so why the hell run it on diluted ditch water?"

    I get better MPG with V-Power. Pre remap I never noticed any 'gains' from using it but since the remap it does seem to help a bit over standard 95 ron etc.

    might be a dumb question but is there a high oc diesel fuel or is it just standard diesel?
