One more comparison

Same set of maps but for a 2>3 up-shift in sport/manual mode

Left is stock 330, middle stock 3.0SI and the right is my current setting.

Yes, I had to reduce the engine torque through the shift to keep the shift smooth. I get a kick but a soft kick.

I can probably push this a little more but frankly this is really time consuming. Nothing like tuning a DME. Think about it, The TCU has something like 18 shift maps to control when it shifts. Then you have up shifts and downshifts in D mode plus Sport/manual mode for each gear. Each shift has 2 main timing maps with matching pressure and torque reduction maps. Each tuned to torque and RPM.

And that's not even discussing the Torque Converter Lock Up clutch maps, All 14 of them. The Diesel guys are really interested in those.
