im tuning a dodge charger 2010, and disabling the neural network to modify the ve tables and nothing change with the A/F.
Help please?

SO you did disable the ANN? If you did then it sounds like the perimeter might be mapped wrong.
yes sir i did but there is no change effect when changing the VE table, Can you please help me .

Do not disable neural network. Injector scaling is the proper way.
injector scaling is the old school way of tuning for commanded.. (Alot of "Branded" ford tuners still do this coz its the easy way)
It would be good to get the VE trims in set, that way you have command of every moment the engine is running.

The Neural network in these cars does not work anything like a Ford. These cars are totally different. The VE tables do not follow percentages and will throw trims all over the place. Will work one day and not the next. It is a very very Complex system!
Fuel enrichment is the fine tuning. This is on VVT cars, older non VVT cars can use VE tables and definitely the proper way to tune them.
Let them disable it and learn themself. It was told 100 times and they dont believe that disabling is the wrong way with the given options to tune.
Would be helpful to understand what mods were done that is creating the need for tuning.
The neural network is above my head on how the ECM makes the calculations. I have try to study it and would take some very complex equipment to truly data log and make satisfactory adjustments requiring many many HRS. Do to the fact that the ECM VVT has to make such fast adjustments, it actually makes the adjustments before the event happens and cks to make sure it did it correctly. Since it is not a mass airflow it takes tons of time to write the software because it is relying on math calculations that are above most I tried to load the formulas but it is too big. I can email it to whoever and see if they get a better grasp of it
All forced inducted mopar vehicles I tune, I tune with Neural Network disabled.
Alas the stock VE table in HP Tuners needs to be adjusted, but thats the reason we tune cars.
IF as said above, fuel trims alter on a daily basis, that also means you are keeping Barometric pressure adapt active, which would definitely change the fuel trims although you did spend hours tuning a VE table one specific day.

VE tables absolutely do no not respond to percentage changes. If remove or ADD 5 % from the VE table on neural network it will not move 5%. so you are guessing what your target is
I tried on the last 3 2015s and none of them responded to VE percentage and trims do not follow. It is a multi tier calibration. Can you explain to me the way the neural network works than?
I'm wondering why the original poster hasn't chimed back in after talking with support?
That sounds very weird.. You should know in order for the fuel trims on the mopar ecus to update it does take a good amount of time unless you have the starscan tool where you can reset them..
