sr20det timing map question

on the timing map of a chip i downloaded before fitting the nistune board

i understand in the fuel maps in raw values you may see values higher than 128

but in the timing map i have a low rpm high load section of map where what seems to be is o2 sensor flags active in and values of around 138-150?

i carried out a map trace and the car seems to drive partly through that section and seems to be kinda laggy

those are knock sensor flags. if it 'thinks' its knocking in that area then it will pull timing / use the knock timing maps

ok that explains it alot, i thought it was o2 sensing

my timing n knock maps are the same so i'll just get a screen shot of the filtered values and copy them into the raw values to get all the figures the same below 100 so its all uniform

thanks again matt
