I would experiment. The OEM GPS is crap and I wouldn’t let it limit what you try. I don’t have experience with a QS to be able to say what is appropriate.My question was a little misleading I think. I am setting up a QS, not an airshifter. I went back and looked at a datalog. Best I can tell it takes about 63ms before it's actually in the next gear, with no activation delay. I adjusted to 65ms kill time with a 10ms activation delay. I think that may be a good starting point.
Thanks to everyone for the advise. Sorry to the OP for the highjack.
