Re: S100 shift cut parameters

I gathered data at 100Hz for the gearchange parameters during the garage testing. Ok, it's with no throttle, and at idle speed, but it gave me the opportunity to play with the data in Excel.
And i remembered to reverse the data!
The blip command is set for 30ms ahead, and you see the barrel voltage start to move 20-30ms after the downvalve has actuated - i.e. 60ms worth of blip. I think I have the blip set way too long (100ms) as it's still going after the barrel has started to move.
I've got an anti-push setting of 50ms which I'll remove for the time being until I've got some real on-track data to check against.
What determines the length of time the downvalve stays open? Is it until the gear pot is within the start voltage of the next gear's central position?
I realise that data from driving (i.e. with high revs and loaded gears) is likely to be different from what I've seen in the garage so will have to wait until Prescott.
Now to put the wheels back on and back on the ground to check the dog/barrel movelent to see how it fits with the shift cut start point value I've got.
