Is there a 1/4 mile timer on my 2017 Z51? I can't find any mention of it in the owner's manual. I found the 0 - 60 timer, but that's all.

No. The "0 to 60 timer" can be set to measure elapsed time from any speed to and speed but there is not a way to measure elapsed time for covering a specific distance.

The "Performance Timing" overlay for the PDR does display 1/4 mile time.

Oops! I forgot about that part.

Cool, how do I activate it?

Hasn't anybody used this timer?

I have used it a few times while using launch control, however, it's a little tricky, the slightest movement will start the timers, so I hit the Start recording after my brakes are locked up. One other thing is it does not account for roll out as done on a drag strip to times will not match what you would get under real timing lights on a prepared strip, however it is close if done right.

Great. Now could you give me the steps to activate it?

Information can be found starting at page 148 of the user manual.

Ensure you have a formatted SD card in the slot in the glove compartment.

Find the PDR Camera in the center screen.
Select it.
First choose video overlay.
Select "Performance Timing".
See right column on page 152
Back out to the main screen and select Start Recording only after you are setup for launch.

Hope this helps.

Thanks, I'm going to go out and try it.
