Hello,

I usually have enjoyed 60 roll race, but recently I found some issues during drag race.

On 2-3 upshift, there are huge dip of spark advance as you can see the pic attached while no problems on 3-4, 4-5, 5-6

fts.

The engine tq source is "Trans S". I think the issue is dealing with it.
When I disable "upshift on Tq Reduction" in Tq management of TCM, the issue has almost gone, but it is quite risky.
