So i gave the search function a good old colledge try before posting, Im having a 1/4 throttle knock issure around 11-14 psi at 3700 ish rpms with an afr of around 11.6-12

. i know our fuel is pinkeln pinkeln (german for pee pee) in northern bc. Was going to hook up my knock ears and see if i hear anything but having difficulty funding a good bung for the sensor.

any help with a bung location and maybe evaluating this timing map would be helpful!Cheers

 

one of the bolts in the middle of the intake manifold or the intake manifold support...
