My Video is Designed to get users on the best strategy, which is using the Staged setup, hence my comment about having the "Exit When Vehicle Speed Exceed" value high for people using the Staged control.johnfelstead wrote: ↑Sun Jan 20, 2019 4:19 pm I have just been watching the Syvecs Help video (which are all very helpful) for launch control setup and something doesn't make sense based on how my launch was setup.
My setup uses the following:
launch ramp mode = hold timer
stage parameters = not used, just uses main tables for control
exit speed = 1.6kph
the speed reference is the gearbox speed sensor
Now based on the help video, Ryan says this is too low and should be set high enough to not switch off launch control until a speed you want it to be switched off is attained. So in my case i would think the shift point to 2nd would be a good option to aim for, say 84kmh
The way it was explained to me previously was the hold timer starts once the exit speed is reached, so the exit speed is the start point for the hold timer to start counting, and not the speed launch control switches off.
The question is, who is right? Is launched switched off at exit speed or is the hold timer triggered at exit speed and launch then works until the hold timer has finished its count up to the max value?
What starts the hold timer counting up if its not exit speed?
If you are not using the Staged control then you should with a Clutch switch instead of just a Speed Exit... as the Torque Reduction tables need to be different for when 0 Load is applied against the Engines Torque (Stage) compared to when clutch is clamped and the drive-train is in the mix for best results..
The Launch STAGE Exit is based on the Thresholds in the Staged Area for Hold time and Exit Speed. When the launch switch goes to off the Hold Timer would start and this as well as Speed is used for the Exit of Staged Torque Control to Main Tables.
