Hour Meter C125

[38D]

There does not appear to be any engine logs in the C125, unlike my C187 which has 4! I was going to use one of the 4 timers to track engine hours instead. Does anyone know what the max value the timer can hold? I need something that can hold ~1000 hours as this is an endurance racing car.

Here's a C127 example file, you can import it into C125 Manager by going to FIle>Open>Import and selecting "Compatible Dash Configurations" from the drop down.

This example uses a Timer to trigger a counter which is then preserved. Using a counter also means you can put in a reset condition if you need to.

So do I even need to do that? I finally found that a Timer can hold up to 42,949,647, but seems to depend on the resolution of the channel. If I allocate to Timer 1 (1 sec) and then preserve the channel, I set a max value of the timer to the 42M value which is >11,900 hours. This seems like it should work fine, or am I missing something?

You have to preserve the channel so that it doesn't go back to zero when you power cycle. It is much easier to do this with the counter than it is with a timer.
