The result is a MUCH smoother car overall and very good mid range response without the off throttle bucking that I hated in the stock tune. To be fair, I think the stock AVCS map also contributes to the low RPM bogging that the STI has a tendency to do along with a very jerky behavior. By modifying the DBW tables, I was able to rid the car of most of this. The rest will come from altering the AVCS tables.
The tables are as follows (entire stage 1 tune is still in progress):
So are you seeing 100% throttle angle at roughly 60% pedal angle for the most part?
