built 4.7HO into 99 WJ. Quick PCM question
 
Ok, a buddy of mine is just finishing building his HO to go into his 99 WJ. I understand the differences in the 99pcm vs the high output pcm from the HO. My question is, Would it be possible to swap the high output computer in and use the harness from the HO, so he could retain the stereo knock sensors? Would the only issue be The key matching the pcm in the jeep? I ask because he's running a ground HO cam, so its more aggressive than the stock HO cam. I'm thinking being able to run it with two knock sensors would help with tuning for the new motor. I know theres the immobilizer thing with the key, so i wondered if that would be an issue. Let me know what you guys think!
