knock sensor desensitizing

[2000_SS]

Tuning a 2012 Ram 5.7 with a mild cam and cold air after a MDS delete.

I've gathered a bunch of info on hemi tuning on here and have disabled the NN and got the VE dialed in. the truck has what i'm assuming is typical hemi false knock based on some testing. I'm logging voltage of the knock sensors and can see how it curves up with RPM as the engine makes more noise.

My question is when i try to desensitize the senors, should i make all 8 cylinders knock voltage the same, or increase each cylinder by the same percentage? I'm assuming the sensors "hear" individually cylinders differently, hence the differing voltage settings.

I have more questions, but i'm working my way through it on my own well enough. I just want to be sure i don't damage this engine. The owner is an older guy that likes to beat the living crap out of it...

do each cylinder by the same % , I have gone as far as 1.5% (50%) cut on the thresholds. I would only go as far as needed to cut out false knock each hemi i have done react differently depending on the fuel used. Only start cutting the thresholds on knock sensors after you know its false knock!!!!!

best done on a dyno, find mbt, then tune knock sensors to trip right at that threshold

Have to be careful doing this though... I've found particularly on Hellcats they will make more power and be faster knocking some right at the edge of detonation

mbt, is not the point of the highest power, in no way did i say it was, its usually a little before. I good calibrator will know what to look for when getting there. if you are picking up 10hp per .5degrees of timing, then pick up 6 on the next .5, then you have just passed mbt. the purpose of the dyno is to tell you where that is. if this is not a safe method, then please explain what the safe method would be

Got it lined out i think....Making 316hp 355ft lbs...totally stock 5.7 Ram with a COMP HRT NSR stage 1 216/222 @.050 cam.

Idle issues i'm having currently are when you rev it in P/N to, say, 2500rpm it will slowly drop back down to the desired idle. But when i rev it higher, like to 4500rpm, it will slowly fall back down and then just stall. It's not a drastic sudden drop in rpm, it just seems that if you rev the engine past a certain point, it's going to stall out. Is there a table that acts like GM's throttle follower/cracker airflow table? I'm guessing idle torque spark or idle torque throttle under Engine>idle>airflow need further manipulation?
