Can timing

[Party340]

Thanks that's what I figured. Problem is, I'm pretty sure on the NGC4 (pre-2012, I believe) you have to disable VVT to fully disable the ANN and be able to tune the VE tables (else it goes into Chrysler black box land). This is per some of my experience on this car and I believe one of 300C's posts. In fact, when I first went in to HP tuners, it had the NN shown as disabled when it clearly wasn't.

Sounds like I might play with lockpin, or at least have a bit of compromise between the two. Dodge makes nothing easy.

I believe that you can use the neuro network trainer to tune with the VVT on (black box land). I have a 2009 and I've skewed the injectors to keep the VVT on. I'm going to try the trainer when the weather cools off. Has anyone tried the trainer on the 09 - 12 Challengers? Seems like it would be well worth it for only 50 dollars.

Hello, I have the same problem. Exhaust cam shows 134 degree, and intake cam 241 degree. So I am pretty sure mechanical cam timing is correct. The car ( 6.2 challenger) has an compcam with phase limiter but the error p0016 is present, cranklearning does not help and I cant delete this error. How can I solve this problem? with this error the whole vvt system is disabled

Are you sure the cam is in time? Thats the dtc saying the cam is not in time with the crank.

[boostcrap]

if it is not in time won't the desired angle and the measured angle different?

[james1595]

Im not 100% sure. Do you have any misfires or does feel off? How far does the vvt go? Perhaps you installed the limiter incorrect

[boostcrap]

vvt wont move, because desired angle is always 133 degree

[james1595]

Its hard to tell, you have one saying the position is 133, and another at 134, while desired is 133.5. Do you have vvt disabled in the tune? Or its enabled but have it at 134 through the tables? I know my car has a limiter but vvt is disabled through the tune and it stays at exactly 125 and never moves.

[boostcrap]

vvt is enabled, at the moment vvt tables are stock

[james1595]

It sounds like the phaser isnt working, which may be throwing the code because the computor is telling it to move, but its not

forget about intake you dont have to keep track of where ea lobe is as they are mechanically connected to one another

134 ECL is full adv for a stock cam. You dont have a stock cam. And you are saying you installed a limiter... How many degrees of cam travel does it allow?

[boostcrap]

Compcams claims it can move 7 degree cam/14 crank

[LilSick]

If cam was ground with massive oem 120.5 degree lobe separation, and properly installed, and could only be advanced or retarded 7 degrees, how could the ECL ever be advanced beyond 127.5?

How much lobe separation does cam have?

*made question bold

[boostcrap]

so lockpin setting is fully advanced?

[james1595]

No, lockpin is usually a few degrees retarded

[LilSick]

not on my 392

its almost exactly LSA

*which would be straight up

[boostcrap]

can anyone post a log? camshaft angle and duty cycle woud be important

[james1595]

not on my 392

its almost exactly LSA

*which would be straight up

Your lockpin is 120, but max advance is 134, so they are different

[boostcrap]

the challenger lockpin is set to 134 degree and max to 135 degree

[james1595]

Unless the hellcat is different, lockpin is 120, max advance is 125 for 5.7, and 134 for 6.4, not sure about hellcat, not at my computor to look

[boostcrap]

this is the stock rom. CAM TIMING.png


so vvt disabled is 134 degree and vvt fully advanced is 97 degree (stock cam) or vice versa?
