Stall out issue when braking and turning M6 truck
i'm having an issue with my truck (in my sig) stalling while turning at low speeds or turning while braking. Never had an issue before cam heads and intake, now me and 2 other professional tuners have not been able to figure it out. We have tried to play with the throttle cracker and followers to no avail. i used the russ k config to tune the base idle airflow so that should be set right, i'm kinda stumped. (I'm not a professional tuner, just a guy trying to learn how to tune my own stuff)

Didn't work for me the other day either. You might have your pcm locked to your HPtuners box only

Need to log Idle Adap (STIT) in the PID's and see what its doing when youre coming to a stop and at idle in gear. Also could be dipping into a lower RPM section of the Map sensor that its not use to. When I tune vehicle I use the scanner special functions and keep lowing the idle to get down into the first column and try to tune as many ranges as I can so when the vehicle comes to idle and under a load and falls into these sections it doesn't bog down from hitting a section that hasn't been tuned yet.

An admin helped me this should work, had master ID on the previous tunes

Can view the file now, but heres what I would do. Put all your air flow tables or even the stock tune back in it. Fail the MAF and set codes properly. tune the VE table first. Then go back with a cold start and dial in the Base Idle airflow and log your Idle Adapt (STIT) pid. Use the vcm commands and keep lowering the idle in gear and also turning the steering wheel to put a load on the vehicle to hit all cells that you can in the 400rpm row of the VE table in case it ever falls in that range it knows the fuel is right and doesn't bog down when coming to a stop and turning. Once you fix that problem then move on to tuning the map sensor.

Changed the Torque management>inertia, Torque managment>Accessory torque, and Torque managment> friction tables and it seemed to help during this log test it never actually stalled which it would do before, lowest i can see is 500 rpm before it would dip into 200 rpm most times. Guess ill try adding to these tables a a bit more.

Did you ever get this sorted out? I am having a similar issue, and not much luck with it.

not really clutch pedal switch is hooked up has an nv4500 trans segment swap and still has the issue although it doesnt stall very often anymore it still drops rpm down to 200 ish when power steering puts a load on engine. Going to try a new PS pump here soon if thats not it then im lost lol
