Default DBW Tables... Am I doing it right?

I've finally gotten a new laptop! This means I can get back to trying to learn all this tuning business...

Anyway, I've tried to modify the DBW. I wouldn't say it's a drastic change, but it is a change nonetheless, and I want to make sure I'm even modifying correctly before I flash it on to my ECU.

For the "Requested Torque A/B/C/D/E/F" tables, I've simply made it more linear.

These are the changes I've made to those tables:



As for the "Target Throttle Plate Position B/Maximum", I've started slow. I've simply tried to make the modified table a "smoother" stock table. See picture here:



Opinions?

You can try setting a direct 1-1 relation, makes the car very responsive and direct but you have to have good foot control to make it drive smooth. feels very much like a cable throttle.

"cable throttle" is essentially what I'm trying to achieve, so I'll definitely give this a try at some point!

I haven't had good luck with this approach. I find using similar to stock values people tend to work the best, maybe ramping them up a little. Similar to what Bamofo posted, just a little less aggressive at lower throttle.
