I created the NN files in VCM and ran them through the trainer and the output were tables very similar (some nearly the same) to the set of tables I get with completely different cam and training values.
Furthermore, now in the NN VE table editor in the drop down for intake and exhaust I have 5 values that say 130 and 5 that say 100, yet the tables are all different. If the NN trainer is actually considering cam values in any meaningful way, I'd expect these 25 tables to all be the same when it creates the initial tables.
So given the above behavior, how can I trust that when making adjustments to tables built with more dynamic values, that the tables indicated by a given cam position actually correspond to what the ECU will reference when the engine is running.
In the above experiment the car would be trying to run with 25 completely different VE tables, all labeled the same, with cams that never move. How does that work?
