2019 300 5.7 - Stalling and Stumped

[Jayuhr]

First post, asking for help. Sorry if frowned upon.

A little background: Being new to the area I wasn?t sure who to go to in regards to having cam install/tuning. Went to a local shop who did great work, but tuning wasn?t right. Found Satera tuning about an hour and a half away so have been there a few times and working remotely with them.

2019 300 5.7 30,xxx miles
JLT Intake
Kooks LTs, Catless Mids, Flowmaster 44s
MMX Cam 218/232

The issue I?m having seems to be somewhat common, but not finding any resolution. When coming to a hardstop or occasionally switching to R or N the car will bog down and stall or nearly stall below 600 RPM. At this point the vehicle does not feel safe to drive with my wife or daughter present as I've had to stop quickly in traffic and completely stalled out.

Have had a few revisions done through Satera and we?re still having the issue. Wanted to see what others? thoughts were and/or resolutions found.

I?ve attached a couple logs showing the issue and current tune.

Greatly appreciate any time or effort given to assist.

I deal with the older stuff, but am very familiar with their(MMX) cams

1st thing I would recommend, Engine>Idle>General>Stopped VSS , raise it to 5MPH, it lets it go into Idle mode quicker, when coming to a stop.
2nd thing, Engine>Idle> Minimum SetPoint, Table 44225(reverse) raise that to 600, tables 35520,35523 (P/N and Drive under Min Setpoint) raise them to 600, see if that helps (* side note)
3rd thing is Engine>Torque Model>Loss>Friction , the 512-704RPM cells, look a little high to me, try X .95 those cells

FWIW Sultan is one of the best tuners that posts here,

*Side Note
We did a 2014 Ram here 3 weeks back, 5.7 8spd, forged pistons, higher Comp ratio, with a cam based on MMX's Chopstick, same duration @ 50 220/232 and LSA110 , but lift was higher, (Ours/MMX) .605/596 .605/559. our tables 44225/35520/35523 were all set to 712RPMs

In my experience even thought MMX says that cam works with the stock 8sp convertor, I feel it's on the edge, and once in a while it "bounces" off the stall and causes a TQ request that confuses PCM , but I don't think that's the case here because you say it's not stalling out all the time or surging at Idle in Drive.

I'll give this a shot in a bit. Jeremy over at Satera tuning has a pretty good reputation, but we all miss things or make mistakes at times. My other guess could be a potential vacuum leak. Noticed that on decel the o2 sensors are registering super lean so it starts to dump fuel when it doesn't need it. Thanks for the info on Sultan - still learning my way around this platform and community!
