I just went to load my tune from Injected Engineering; but I noticed I had to codes. one was the p0325 and the other was b1251. I decided not to load the tune, and google these first.

the knock malfunction code seems rather frightening. What could be causing this. I don't think I have knock, but I don't really know how to tell. I am taking it to the dealership tomorrow to have it checked out. I just hope they don't blame it on my k&n typhoon CAI.

Thanks

EDIT: could I somehow done something during installation of the K&N filter that would have cause knock?

P0325 says "circuit malfunction" in the DTC listing you can find in the General Tech Chat "Stickies".

First check for that is to make sure it's still plugged in...

You can get the knock sensor code for many reasons

Bad knock sensor
knock sensor indicating knock above its ability to retard


You wouldnt hear knock with a knock sensor , what the knock sensor does is remove the excessive timing to remove knock

If in fact you have knock , I wouldnt add a tune that adds more timing with out datalogging and sending your tuner some logs
