Flex fuel kit tuning question
 

I emailed Delicious Tuning twice regarding this question but my question wasn't answered.

I know I have to get a tune to use ethanol but can I fit the flex fuel kit, not get a tune and not use ethanol?
That is, does the flex fuel kit alter the map for 100% NON-ethanol fuel?

Ta.

You can get the kit installed (fuel lines and sensors and whatnot) and not wire it into the ECU and it simply does nothing. If you wire it in however you are changing one of the inputs to the ECU (CPC pressure if I remember correctly, if not the rear O2), at least it is for the USA models. Not sure what it's used for on other regions. That may trigger a code or other issues.

Bingo!
Thanks.
