NGC4 Comp HRT throttle hang

[StupidJeep]

So Ive managed to develop a throttle hang on decel off the gas and only at around 1000rpm. I can rewrite the same tune into the Jeep and it wont hang but after a couple days it will come back. Doesn't matter whether I reset adaptives or not.
Looked at the usual suspects but but no luck figuring it out with the limited tuning knowledge I have.
Attached current tune and a short log. The last 30 seconds of the log really shows the hang. Yes the VE looks like garbage at the moment. I have had it lean, rich and cleaned up and it will still hang.

Any insight is appreciated!!

I also have a NGC4 jeep commander running a healthy 224/234 camshaft. Right around 1k-1500 i would get an annoying rev hang, especially between gears.

My solution although not elegant, was to reduce part throttle timing in those areas. I tried every trick i could with throttle control. Pedal follower, friction torque, small/large/model airflow.

I reduced my timing to 6-8 degrees at 0.20 aircharge between 1200-4000 rpm. and i would ramp it up 3-4 degrees per row until back into "normal" part throttle ranges. so at 0.30 im at about 12 degrees. I applied this to all VVT part throttle tables as well.

It honestly has eradicated my issue entirely.

sucks vvt spark cannot be disabled in the next gen controllers

thank god dodge released the hellcat tho...

otherwise we prolly would not be able to disable those tables in the gpec2a either


*there is a work around tho - what cannot be disabled can often be made identical : )

After making the changes that were suggested it still did a hang and a bit of surge at the same point a couple times. I wrote to the ECU again with a minor change to the trans for when 4-5 up shifts, so unrelated I would think to my original issue but it hasn't really hung for the last few days...
To what LaBrat is saying I didn't think there was air charge or vvt on the NGC4 os?

my NGC4 is on a 2010 Commander, so it has VVT. Sorry i couldnt be of more help!

Hello to all of you. I have the same Issue. My car is a 2005 300C 5.7 with a swapped engine to 6.1 and a CompCam 278. I tried so many things, changed the tuner, tried another Tuningsystem, but nothing works. At the beginning I had a NGC3 ECU, but this won't work at all. Now I have a NGC4 and everything is fine. But, if I drive the Car in the City, the last tuning file was flashed and some warm up cycles are done, the car hold the gas between 900 and 1200rpm. I need to brake the engine down to 900rpm to stop. Thats so ugly. Only if I lower the friction loos table, it works but the engine shakes badly at idle without driving. Can someone help me out? I do not want to reinstall the original cam.
