About value knock control very high, i add that i have the same problem.
Last week i saw 1.14 also, after a WOT in 4/5/6 gear.
So, another person i know has the same problem.
All three person with a bad fuel? I have some doubt...
First question, yes
Second question, yes
Third question, no. You can use map 3 with or without the ktuner plugged in.
Without the ktuner plugged in, when you turn on your Civic you must set map 3 using the cruise control button.
