If you had the simplest of understanding on how these ECU's protected the engine then you would not be saying it is OK to run on 95Ron fuel.

Due to me getting bored of you now I will give you a little help.

Running lower grade fuel will tend to make the engine run lean.When the ECU picks up on this problem it will pull the ignition timing thus retarding the engine.It will also dump more fuel into the engine in an attempt to prevent engine damage.

Now can you see the little problem with running on the lower grade fuel?

Thats what i said 3 posts back mate therefore increasing mpg on lower grade fuel, you just keep repeating what ive already stated, basic engine management they teach you first year in college

Think you need to revisit first year teach mate

I will explain just for you, lower grade fuel (lower octane) will cause the engine to run leaner, when the oxygen sensor detects this it alters the timing and increases the amount of fuel as you said yourself hence using more fuel in the process, with higher octane stuff this doesnt happen as much hence less fuel used, anyway never mind first year college this is like being at junior school bikering its getting BORING!

Soory, typing error i did mean decreasing mpg, but i think you knew that

It just goes to show your general knowledge regarding tuning cars when you are trying to compare n/a engines to turbo charged ones.

What are the benefits of running the higher Ron fuel compared to the lower grade on a turbo charged car?

now at no point did i say what sort of cars i've had ! but for the record i've had chipped cars in every form bar LPG !! i've read further on in this thread and see you made a mistake with your claim about the must of 97 ron fuel ! i think we have an understanding now ! for optimum BHP/ ECONOMY high grade fuel is the way to go ! but otherwise 95 ron in a chipped car is just fine ! the choice is down to the owner !!

YES there are benefits from running on high octane fuel but i can't justify the cost for what i use my cars for ! and i'm in no doubt that some have had bad experiences with chipped cars ! though i've never heard of anyone and certainly the circle of friends i have with modded cars have never had any trouble !

Are you sure about that?
