IM pretty sure its only the bar, ive tried getting a number reading instead....considering how important knock is, why the **** would they have some poxy bar instead of a number,
But in a way its a good thing due to the max reading, and logging/resetting.
In 4th gear i got 65 knock readings at 6700rpm due to my injectors maxxing out, i need to go for a fine tune AGAIN, 3rd time lucky hopefully.
I have had readings of max 128 in 5th gear around 4000rpm.
Time to reduce some more timing, need new injectors
