    Removing the "Use table for training" checkbox tells the Neural Network Trainer that Neural Network output values in that area do not matter. This allows it to focus on areas which are actually used,...

    Can you upload the HTT file here? I'd like to take a look at it.

    My point with that post was that if you make changes to the camshaft angles in "Engine > Airflow > Variable Camshaft", you should also write the new min-max ranges in "Engine > Airflow > Neural...

    I'm glad my answers helped you out!

    As for tips, I think the main one is that the neural network trainer always tries to minimize average error across all tables. That means that some areas might...

    The neural network uses the camshaft angles defined in “Engine > Airflow > Variable Camshaft”. If those values are modified, the values for min/max intake and exhaust camshaft should also be changed...

    The Neural Network FAQ explains this in the "Do I really need to modify all 25 VE tables for FCA vehicles?" section.

    For best results, all tables that are marked for training should be filled in with accurate data. You can do a regular log using VCM Scanner and then filter out fuel trims by intake and exhaust cam...

    Yes, those 5 tables look right for a FCA vehicle where the intake and exhaust cam angles are linked together. Make sure to uncheck "use table for training" for the tables you're not using before...

    Tokens are universal. You can use them to license neural network training for any vehicle that supports it.

    To access the Neural Network Trainer, open a tune file which supports neural network training, and click Edit -> VE Neural Network Trainer.

    We added 2 new parameters with the latest VCM Suite Beta(4.9.389). "2077 - Intake Cam Angle from Open Position" and "2078 - Exhaust Cam Angle from Open Position". PID 2077 should have the same value...

    I asked one of our engineers who specialize in GM tuning about this. Will post an update once I get a reply from him.

    The activation function is something that's part of almost any neural network, not just the FCA/Dodge NN. zhc's explanation of the activation function was pretty good and probably as good as it can...

    The neural network is used to estimate Volumetric Efficiency in some Dodge and GM PCMs. As far as I know, their TCMs don't use neural networks.

    Training a neural network is a resource intensive task. Running a neural network, not so much. The ECU's can run the neural network, but they can't adapt to changes made to the engine. That's why...

    As far as I know, all Dodge/FCA vehicles have the same activation function and we don't recommend changing it. Doing so can result in unpredictable behaviors in the neural network.

    Hi, I don't think I understand the original question, do you mind rephrasing it?

    During training both the neural network weights and the biases are changed.
  19. All inputs to the neural network are normalized...

    All inputs to the neural network are normalized between the minimum and maximum value. That means that if you set the PRatio range to 1 - 1.01, all pratio values below 1 will be considered as 1 and...

    It is up to the user to decide how they want to modify the VE tables. They can use fuel trims or any other method they like.

    The Neural Network Trainer is intended for all FCA and GM vehicles...
