I know it's up to me to see whats best for my system but I wanted to know what experience is out there with false knock or overly sensitive system. 383 TPI (EBL) in 89 K1500. Was using BLH ESC module with correct knock sensor for vehicle (mismatch), I am going to try going back to the correct ESC module and log, has the matched knock sensor for the BLH module proved to be best, just want to be sure before purchasing ACD 213325, have ACD 213324 installed with 45deg elbow. Robert R says they will work together, my reading suggests match components.
