Can someone tell me how I can get rid of this tq man right after the shift? It lingers for a bit then I get my full timing. @ 1:14 and 1:17 WOT 2-3 and 3-4 shift as an example. Shift feels good, but there is tq man advance after the shift. Log and tune attached. Thanks in advance.

I had a similar issue but throttle closing. In your log you can see trans as the torque source during the timing pull. Guess it is either slip related or some torque value is exceeded. Log trans slip rpm and see if you have some slip, in that case you can increase oncoming clutch pressure and it may go away. If not some torque limit is probably exceeded. Yet I have not figured out the exact cause to why it shows up after shifts (basically as long as the oncoming clutch is active or slip is present) but I had luck lowering the MBT timing tables where needed to change the reported engine torque. I find it easier than messing with the virtual torque tables.Quote:

You can also see the airflow problem by comparing throttle desired airmass vs. cylinder airmass. Cylinder airmass is always higher because the turbo is forcing the air through. The throttle blade airflow equations assume there is always barometric pressure on the front of the throttle blade, but with a turbo that is not the case, so more air moves past the throttle blade than the computer is expecting.
It looks like there are a lot more bad shifts in this log.. 1:51, 1:54, 4:58, 5:00, 6:15.. all caused by the same problem.
Looks like your BARO is stable, so you must have done the breakout, which helps the VVE, but still doesn't control the throttle properly.
I fixed this by changing the Map config to TC-MAP-TIAP-BARO.

The driving and shifting is wayyyy better with this setup. I think it is a critical step when turbo charging any GenV ECU car.
Also, looks like you need to raise your peak torque from about 4800 rpm through 6500 rpm. Your WOT shifts would probably be fine if you just increased that.
Good luck!
