I know you cant adjust the torque heading in the throttle opening % table. I tried that, mostly because I'm used to GM ecus that do a lot more complex math with the requested torque and having the max be 400 vs the 320 that you can put in the throttle opening % table heading would make a difference on other parts of the tune. Doesnt seem to be a big deal with ours, just have to realize that if you just copy a sti request torque vs pedal position map to a wrx that you will be 100% throttle plate opening at 80% pedal. At least for 06.
On that vein, OP, look at your headings for throttle opening % requested torque should be the units on the column headings, any changes I make to open source in those dont stick so you can only really use 320 as the highest value in the requested torque table, anything above that doesnt really do anything. Just realized you have a 06 wrx so I can post my "stage 1" tune like around 10 tonight, and you're free to steal the throttle mapping, and anything else you want. It pulls all the way to my rev limiter at 7k.
