I have managed to set up a timer to record engine run time in the C127 however it resets every time I power off the display, is there a way to stop this happening or possibly a way to send that value from the M800 instead

Functions - Preserved Channels - Add.
That should do it.

Thankyou I'll try that this weekend

I tried that and it still reset when I powered the display off and on
I had the options set to preserve every ten minutes or when engine rpm is below 500rpm

I found an old post describing how to make this work with a counter, in that post it was mentioned that setting the timer itself as a preserved channel was more complicated, exactly what is involved?

Preserving channels in Dash Manager can be a little bit complicated because of the way the system works in the background. There are limits how often it will preserve channels and it isn't obvious from the outside when/if a channel is actually being preserved.

Below is an example C185 file (that's what I had on my bench, but you can do the same thing in any of the colour dashes) which will preserve a timer that runs whenever there is Engine Speed. It is preserved every minute or when the Engine Speed goes to zero.

A couple of things to note:

If you turn the Dash off before the Engine Speed goes to zero you can lose up to 1 minute of run time.

The timer will only run to 42949672 seconds, which is just under 12,000 hours.

Thanks Adrian I'll take a look at the file tonight

Any chance you could post screenshots of the relevant config

I have this working now, thanks for your help:-)
