I bought my 2010 sho non-pp at 28k miles(2 years ago) and had some initial issues with a blinking CEL. The dealer couldnt replicate but it happened usually when i tried to pass someone or merge. After much research i decided to just change the plugs to cover my bases as i heard about the 2010 plugs wear out prematurely. This corrected the problem entirely.
I debated tuning the sho forever till i finally pulled the trigger and got a SCT X4, 3bar and thermostat. I loaded the tune and it was amazing i couldnt believe the power it put out and the throttle response. after playing with the tuner i decided to look at the knock readings as ive heard of alot of issues related to the sensors detecting knock and pulling timing. to my dismay i see a max reading of 7 and upon looking at the datalog i noticed it would happen everytime i floored it. I went back to stock monitored the knock again and still saw knock readings as high as 5-7. Ive since tried every gas available to me in canada and they all get atleast as high as 4 degrees at wot. Changed the plugs. Ran a few bg treatments through the engine and the gas. nothing really helps at all. I checked my knock sensors for chafing on the block like some others have but i have wraped those wires to no effect aswell.
Im just looking to make a list of stuff to try before i end up trading it in on a new vehicle if i cant fix it. all i can think of is replacing all the air sensors and the o2s. Oh ya i also got my bank 2 o2 sensor replaced but that also didnt fix the knock.
