I've been chasing +knock readings for a while (see my earlier posts in this thread). I found/fixed a couple of small things over the past that I thought may have contributed to false knock, but nothing solved it. I of course tried different fuels, torco, etc.. Knock was still present. I figured my next step was to access the intercooler to check for oil contamination but put that off and just didn't drive the car much.
During the recent holiday sales I purchased a PMAS 120 intake kit just to test. I installed that along with an older monoblade throttle body I had sitting in storage that I hadn't tried yet. I replaced the dual 65mm throttle body and JLT 127mm Carbon Fiber air intake with the monoblade & PMAS parts. Contacted Lund for a tune revision & flashed it in.
I've run this setup for the past couple of weeks and NO KNOCK! It's actually adding timing now. I'm reading up to -3 on the knock sensors now! It idles so smoothly now that I caught myself checking the tach at stoplights to make sure the car hadn't cut off on me (it was somewhat rough before).
I'll definitely keep an eye on the data logs to see if it maintains this behavior as the warmer weather arrives....but man is it great to see the knock sensors adding timing for a change!
