In our independent tests in a range of cars, BP Ultimate 102 gave typical power benefits of between 4 and 7.5 per cent above 97 octane BP Ultimate Unleaded when the ignition was remapped. On a high performance, turbo charged vehicle, with boost pressure increased, the power benefits seen included an increase in maximum power of 37 bhp (8.6%), and as much as 60 bhp (16%) at some points in the engine speed range.

Tesco99 (Greenergy) do something very similar, but its twice the price (£2.21/litre)....I suspect the BP fuel will be much the same.

If you use this 102 ron fuel, will it take 4-5 tanks of this fuel for the ECU to work out what its using? I was told if you went to unleaded then back to optimax, it would take several tank fulls for the ECU to adapt??

dont know about that, but a very quick way for your ECU (a jump start if you will) is to reset the ECU its self. once back on it will work out right away what your are running on.

my last car if i added a different ron etc i would just reset the ECU then take her for a blast, i was told to then drive it like mad man for 10mins because it will set itself to performance mode. but that was my last car not this one. so whats the story here?

For £2.30 something a litre. I would want my car to learn REAL quick!!
I live in the Midlands and wouldn't mind trying it by purchasing a couple of containers full of this stuff. It would be pointless if I couldn't reset the ECU.
My other question is when you have your ECU remapped. Doesn't it keep the settings to tell it what petrol your using? If you reset this wouldn't it go back to standard fuel?

If you re-read BP's blurb:
In our independent tests in a range of cars, BP Ultimate 102 gave typical power benefits of between 4 and 7.5 per cent above 97 octane BP Ultimate Unleaded when the ignition was remapped. On a high performance, turbo charged vehicle, with boost pressure increased, the power benefits seen included an increase in maximum power of 37 bhp (8.6%), and as much as 60 bhp (16%) at some points in the engine speed range.
Basically you'll need to have the car mapped to the fuel to see any benefit.
Having the car mapped to 99 and a bottle of Millers (allbeit 1 octane lower) would acheive almost the same effect and be a lot cheaper per tank.

Unfortunately the effect of this learning process, which is going on continualy, is that it may learn some bad habits! Early models of MY96 and older needed the memory to be reset to take advantage of changing from normal to super unleaded as the ECU remembered the optimum settings for the lower grade fuel. This also meant that is a bad batch of fuel was used then it was this which was remembered. Newer MY97 to MY00 models relearn a bit better, the MY99/00 being faster than the MY97/98 but this process can be speeded up by a reset also. There is no mileage in resetting the New Age WRX because of major differences in the ECU/software.
