I have heard of this problem before but of course no one can tell me how to fix it. Any suggestions that aren't going to cost a fortune?
Get your PR3 chipped and get the knock sensor disabled. Knock sensors are very picky and ECU knock sensor programs (and hardware) are highly tuned to a specific engine setup, so if you have a B16 knock sensor on a LS block then you're probably going to have problems. The LS setup probably has a different harmonic frequency range than a B16.
