What else could be the reason for the timing correction if its not Octane related?

@enrita:
I have ATR installed on my laptop so I could make an Ethanol map.
But is it really that simple? One parameter (2 times because bank1 and bank2) and thats it?

And how much should I change it? Now its 1?

Will the car afterwards always use more fuel. MPG get worse also while driving normal 98RON?
Or do I have to switch back to the other map when I don't have access to E85.
yes you need to change the scalar bank 1 and 2 for the amount of ethanol you are putting in and then always use the same amount. if you go straight 98 than you need to change map.
there is a pdf with the values , just search for the thread cobb opened about it.
