Just flashed my car on the weekend on STG1 pump gas map (only mod i have is Perrin panel drop in and Perrin header back). car seems to be fine and there are stronger pull from 2500rpm then hit the torque dip then pull strong again from 4000rpm.
however i seem to hear some knock sensor sound around 3000 - 4000rpm. is it normal or is it the DI sound? i don't think i heard this before flashing.......
would data logging capture this? ambient temp was around 22 degrees C (around 72 degrees F), water and engine oil temp were warm and normal.
thanks.
