-do these use throttle delays or limits to prevent detonation?

any other info you can give me would be much appreciated



Cams run to the lock pin after start up. Not sure how much can be done about changing it at idle. I haven't fabbed up any "manifolds" for my 3.6l so its loud as hell for the 1st 30s and then the cam timing makes an obvious change and the decibel levels slowly drop by 2/3.

I haven't seen any setting the PCM as far as Oil pressure control in HpTuners or Diablo, so unsure about the when but I'd guess RPM and load.

Cam timing is used for psuedo-EGR like affect to combat detonation.
I don't see any Throttle modifiers associated with Knock.

I'm not aware of any Pentastar with a variable intake. I know my Jeep/Ram intake and my Caravan intake do not. im not sure of the 2016 and newer PSU engines


NO the 3.6L doesn't share the bellhousing with much anything but maybe a 3.5L


atleast as of 2018 they all have an intake runner length valve

what are you using for an ECU? it sounds like you are able to read from it?
fly by wire throttle?
what donor vehicle? what all came from the donor vehicle?
where is the O2 sensor? does your ECU require the after cat sensor?
any other trap, pitfalls, or dragons to be aware of?
