hello i had a pretty scary situation last night thought i threw a rod. got superknock on cylinder 4 i have a video of the pull when it happened and have logs of it happening. it came with bank2 post cat 02 code but come on that didn’t cause the superknock i also notice that timing is being pulled or it’s pre igniting i do have 17ts on mhd stage2+ ik it needs a custom tune but i also don’t think that caused superknock my concerns are injectors, false knock, carbon buildup causing hung valve, etc. i have replaced plugs and coils brand new 2 step colder and i have a walbro 450 lpfp which was working fine at time of superknock i will try and post video and logs etc of when it happened, i just replaced bank 1 rear 02. i also have msd81 dme so it’s not mofsets i don’t think it’s still possible. i have spent over 3-4k in maintenance in past month. have stuff for walnut blast just hadn’t done it yet i was waiting for a few days off work. i reflashed it runs normal atleast for now
