Drag racing launching question/problem

[Pocket]

I've had this happen twice when at the race track. I go to spool up at the lights, and the guy in the lane next to me takes a second or two longer to stage than I was thinking, and suddenly my truck will upshift into 2nd gear before I've even launched.

So looking under the functions, there is a setting called "Upshift Speed w/failed VSS". I'm assuming that the reason my truck upshifted was because it thought that my VSS failed. So if I raise the RPM's across all the throttle positions in this map, will that prevent it from upshifting when I'm staging? Or is there another map I should be looking at?

My thinking is that if I raise this to an RPM that's higher than what I launch at, then there won't be an upshift while I'm staging. Am I correct?
