All good points. To SST159 there is no way to get any of the timing system info into a data log so we use some item in the car to start the run.

Here is what I think on the subject:

- As mention above, unless you have a 8 magnet collar, I would not recommend using the DS movement for the start point.
- Yes the G-meter is my #1 recommendation for the start point.
- I sometimes use the RPM jump when TB releases because it's a bit easier (that was the reason in the vid) and it really is the mechanical beginning of the run. If the valve body, or TB solenoid, is not releasing exactly the same this is how you see it.
- It's important to remember that this is not a permanent change to the log file - you can reset the start point at a later time.
- Sometimes if I am overlaying more than two runs I will purposely offset the start in the runs so I can see overall picture better.
