Knock sensor codes

Recently purchased a 01 corvette and pretty much right away I’ve been getting knock sensor codes, the check engine light has been on and the codes are p0332 and p0327, I’ve taken it to a Chevy dealership in my area three times now and they are struggling to find the problem. the engine has been swapped to a 6.0 out of a 07 truck I’m pretty sure it’s the lq4 the dealership has just been throwing parts at it and since it’s not the original engine it seems they don’t know what to do. We’ve swapped the knock sensors and put a new ecm in it any ideas what the issue could be?

Your ECM is designed to read the knock sounds of a 5.7 engine so it can adjust the timing and/or throw a code if the values are off. Your engine 6.0 swap will "sound different" than a 5.7, so your sensor is reading the difference sound as a fault.

You may need to do some tuning where the tech adjusts the knock sensor to be "less sensitive"
