I'm wondering how I can ever change these numbers on the dash, Best/Previous/Current. I've run Track PDR for 0-60 and 1/4 mile. Nothing I do seems to ever make them work.

On a side note, is it normal for my Tranny Temp to barely go above 100? This was after 1 hour driving.

Scroll down to the LAP TIMER screen and then right to the RESET button. Play around there. Timer values are also displayed on the STATUS display you have pictured.

Info on all of the DIC displays:

Yeah, trans temp doesn't go up much when just driving around. I seldom get to half scale of the display. M7.

Great info. Thanks!

So looks like this diagram doesn't completely apply to me as I have no option for Lap Timer. Still have no idea how to make these numbers work. Does no one have a clue?

OP. Your picture shows that you are in Track display mode, Performance, Status display. Push the down arrow under your right thumb and check out the other displays. One of them should be Lap Timer. Push the right arrow and you should see RESET and some other choices. Once you start lap timer, you can scroll back to the Status display. IIRC you can push the button inside the 4 arrows to advance lap by lap. Play around with it.

I've done nothing but play around with it. Thing is, I don't have lap timer. I have performance timer, which I've used before, but it does nothing to change those 3 dash numbers. I've looked at every single thing I can change and nothing seems to indicate using those number in any way.

OK - sitting in a cold garage with 8" of snow outside I see the following in my 2014 Z51 M7 built April 2014:

In TRACK display mode:

Scroll down to Performance Timer:

Lap Timer

Scroll down 1 more time to Lap Timer:

Lap Timer

Press the right arrow with your right thumb:

Lap timer / scroll right

Select Start Lap Timer (up arrow, SEL), display changes to this with CURRENT time running (stopwatch next to mode T apparently indicates that a timer is running):

Lap timer running

Press SEL to end lap / start new lap:

Now past first lap. Current time running


Scroll down to Lap Timer:

Back to Lap Timer screen

Push right arrow:


Select Display Lap Times:


Lap Times displayed


You can select STOP LAP TIMER when you want to. BEST, PREVIOUS, and CURRENT times will be displayed until you select RESET LAP TIMER. Notice stopwatch symbol is no longer visible with timer stopped.


This is how the Lap Timer works on my 2014 Z51 M7. You don't say what year / model trans you have.

OK,

I remembered some old threads discussing missing timers. Just searched C7 General for "timer"

Looks like you are out of luck if you have a PDR (PDR was not available until 2015).

This Service Bulletin says no Lap Timer if car has PDR:

Apparently some 2016s didn't have the Performance Timer - but could have it restored:

It sure seems dumb to have the dash numbers like you do that have no function - unless driven by PDR. You could set a start/finsh line and circle the block a few times to try the PDR lap timer and test this.

Anyway, I now know more about the Lap Timer in my vette than I did before.

Enjoy your car.

When you have PDR it automatically tracks lap times using gps when you are on the track.
